  1. Recently I check Rohan Dalvi Procedural texturing and baking lessons and it really useful for learning Texture Baking. But the reason I bought this tutorial series was to get a better understanding behind the concept on baking. What I really want to learn is, how to bake lightmaps using Redshift, but there is little information on the subject. I check the documentation on the redshift website (https://docs.redshift3d.com/display/RSDOCS/Baking), but honestly, I don't understand anything even after I learned how to do texture baking. The process goes like this: 1. Creating an appropriate unwrapped UV channel that will be used by baking 2. Creating and configuring one or more bake sets 3. Setting up the AOVs 4. Executing the bake It starts for me at step 2, do I need to use the bake texture note? 3. Why do I need to set up AOV and how is this connected to the bake texture note. Am I missing some important information here? If somebody could explain to me step by step how do to create a Lightmap using Redshift? Currently, I'm using Houdini 16 and Redshift 2.5.32.
  2. With the help of both the Redshift community and resources here, I finally figured out the proper workflow for dealing with Redshift proxies in Houdini. Quick summary: Out of the box, Mantra does a fantastic job automagically dealing with instanced packed primitives, carrying all the wonderful Houdini efficiencies right into the render. If you use the same workflow with Redshift, though, RS unpacks all of the primitives, consumes all your VRAM, blows out of core, devours your CPU RAM, and causes a star in nearby galaxy to supernova, annihilating several inhabited planets in the process. Okay, maybe not that last one, but you can't prove me wrong so it stays. The trick is to use RS proxies instead of Houdini instances that are in turn driven by the Houdini instances. A lot of this was based on Michael Buckley's post. I wanted to share an annotated file with some additional tweaks to make it easier for others to get up to speed quickly with RS proxies. Trust me; it's absolutely worth it. The speed compared to Mantra is just crazy. A few notes: Keep the workflow procedural by flagging Compute Number of Points in the Points Generate SOP instead of hard-coding a number Use paths that reference the Houdini $HIP and/or $JOB variables. For some reason the RS proxy calls fail if absolute paths are used Do not use the SOP Instance node in Houdini; instead use the instancefile attribute in a wrangle. This was confusing as it doesn’t match the typical Houdini workflow for instancing. There are a lot of posts on RS proxies that mention you always need to set the proxy geo at the world origin before caching them. That was not the case here, but I left the bypassed transform nodes in the network in case your mileage varies The newest version of Redshift for Houdini has a Instance SOP Level Packed Primitives flag on the OBJ node under the Instancing tab. This is designed to basically automatically do the same thing that Mantra does. It works for some scenarios but not all; it didn't work for this simple wall fracturing example. You might want to take that option for a spin before trying this workflow. If anyone just needs the Attribute Wrangle VEX code to copy, here it is: v@pivot = primintrinsic(1, “pivot”, @ptnum); 3@transform = primintrinsic(1, “transform”, @ptnum); s@name = point(1, “name_orig”, @ptnum); v@pos = point(1, “P”, @ptnum); v@v = point(1, “v”, @ptnum); Hope someone finds this useful. -- mC Proxy_Example_Final.hiplc
  3. I assume I'm missing something obvious. When you have multiple redshift rops how do you specify which one is used for IPR rendering? The Render View only allows you select from Redshift_IPR ROPS. So I'd like to have a Redshift_IPR ROP for each Redshift ROP. How do you explicitly define this connection between the Redshift_IPR ROP and the Redhsift_ROP? The "Linked ROP" attribute doesn't seem to do anything. I'm a little lost. Please help. Thanks
  4. Stark Houdini Palm Tree FX

    Link to Course In this 3 hour course I show you how to setup a system for dynamic and unique palm trees. No two are alike. I start from the very first leaf and go all the way through to rendering with Redshift in the most efficient way possible. At the end you will understand how to make your own trees and take these concepts and apply them to other setups that will bring your skills to the next level! Includes 13 Chapters and the final Houdini file. Also the assets to follow along. Full HD
  5. I have a dynamic volume that I want to render with redshift. It is not a pyro sim but when rendering the density changes as a function of time, so by about frame 100 it has dissapeared. I want it to stay the same. I cant find an attribute in the redshift volume shader related to time. Can anybody help me? I basically want the render to be the same on frame 1 as it is on frame 500. The volume is generated via a point cloud that is rasterized. THanks!
  6. Hey, I took advantage of some of the price drops on GPU's lately with the release of the 20 series cards from Nvidia. I Got an evga 1070ti ftw2 card for 429$( also has a 20$ MIR to drop final cost to 409$). I put this into my machine that has had an evga 1080ti FE card in it since I built it a year and a half ago. I wanted to share the "real world" test results in case anyone else is wondering if it is worth it to pick up another card. The PC is running win10pro, 64gb ddr4 ram, intel i7 6850k 3.6ghz, primary drive is a samsung 960 evo m.2 ssd and a secondary crucial ssd, 1000 watt evga gold G3 psu, Houdini 16.5.268 and redshift 2.5.48 ( i think ) etc... I ran a redshift test on a scene that is a decent size pyro sim, rendered 60 frames at full HD with fairly hq setting. With just the 1080ti in the pc, the render took 38min17seconds. With the addition of the 1070ti, the render took 25min26seconds for the 60 frame sequence. Adding the second card took almost 13 minutes of the sequence render time. I would say it is worth the roughly $400 bucks. With the option of enabling/disabling gpu's in the redshift plugin options, I ran a single frame of the render and here was the result: with just the 1080ti - 26 seconds for the first frame. With just the 1070ti - 34s, with a little boost to the gpu settings on the 1070ti using the evga overclock software - 32 seconds( not enough for me to want to keep it overclocked beyond how it arrived). With both gpu's enabled - 15 seconds. I think I would be willing to buy another 1070ti while the sale/rebate is going on if it will reduce the render time a further 13 minutes. I'm assuming it would, but maybe I'm not adding something up right here. If adding one 1070ti to the machine cut 13 minutes off the render, wouldn't the addition of another 1070ti take another 13 minutes off the render time.? It would be incredible to drop the test sequence render time down from 38 min to 12 min for roughly $800 in hardware upgrades.! I ran all the PC's parts through a component checker online and even If I add a 3rd card, it should still have about a 100watts of buffer on the 1000w psu. Would probably want to add some more/better case fans if increasing the GPU count from one to three.! Anyways, thats what adding an extra card did for me. E
  7. Hi I was playing with this wool effect .otl and it works for the main thicker geometry but I cannot get the fine fluff / strands with Redshift. I have enabled OBJprams on the strands and enabled render as strands in the redshift settings but the finer fluff that he is getting with Mantra does not show with Redshift. Anybody want to save me hundreds more minutes trying to figure it out? Thanks! Video: https://vimeo.com/243011851 Otl file: https://www.dropbox.com/s/6eg0uyhzqm1fdr6/Create_Wool.otl?dl=0 Ps: If there are better methods for wool/felt effect I’d love to know!
  8. Hi, Has anyone seen much information about the latest Nvidia cards that will be coming out end September in relation to GPU rendering.? I have been waiting for the specs on these cards for months, and finally they have been released, but of course all the articles so far that I have seen are still somewhat speculation on performance and "leaks" of specs that may or may not be real and all are geared towards gaming. I must say, some of these leaked tests aren't too impressive, like 5% performance increases on the new GTX2080ti over the old 1080ti, but I would have to assume that's because the software doing the tests isn't taking advantage of the RT and tensor cores. I am disappointed that on a $1200 card, they still only have the same 11GB of ram as the 1080ti has, although it is faster/newer ram, I was hoping for more ram.! Have there been any statements made by redshift or otoy about what speed improvements will come form having a card with "RT and tensor cores"..? Just wondering because I will be needing another 2 gfx cards in the next month, and the 10 series cards are having great price drops recently, some 1070ti's are as low as $399. If these new flashy RT cores are going to be a huge performance gain, then I will probably hold out for at least the 2070's. Any info would be great. Thanks. E
  9. I'm emitting smoke with colors. After adding and creating dop fields import with density, vel and Cd channel for rendering the colors are not visible in the render. When I'm visualizing them as color channel everything works fine. How can I make volume colors visible in Redshift render?
  10. Droid_v1

    Hi all, Here is a quick doodle in Houdini + Redshift + DAZ. Any comments are welcome. Cheers.
  11. Hello everyone, I am new to houdini, and I am trying to do something I think should be simple, but I can't wrap my head around how to set it up correctly so that it works. I want to transfer a point attribute from points generated on a source mesh, back onto set mesh or ideally into a redshift shader (RS_material) to control the opacity. I am trying to use the super cool tutorial below, and use the points generated to drive the reveal of a mesh through the use of the opacity channel in the redshift shader. I can't seem to understand how to set this up so that the parts that need to see each other can, and do I need to convert the attribute into something that can go from 0 - 1 and / black to white? I'm just a bit lost and im sure I over complicate things, so if anyone would please just point me in the right direction at least, it would be much appreciated. Like what is the general basic order I should of this? mesh - generate points - I can see the attribute in my geo-sheet but now what? attribute transfer I can't seem to use correctly Thank youuu !!!
  12. Houdini Lighting Artists - ETC LA

    Hey guys, we have a big need for Houdini Lighting artists here at Electric Theatre Collective LA. Any referrals are also welcome!
  13. I want to scatter some trees as instance .rs files on my ground. I have a trees that contain around 130K points. I have scattered them on a grid, using redshift proxy files and instance. +My apporach: export each tree as .rs import on redshift proxy node. instance proxy scatter on grid the end.... rendertime fuqqen slooow(or is it)? +My comptuer: 32gb ram graphic cards one nvidia 1080 gtx and one nvidia 1070 gtx I have 1000 trees scattered, when i try to render the trees up close, one frames takes around 2 minutes to render, is this slow? When I checked out Atoms video on how to do something like this, he had a much faster render response, but his obj/rs. files was lower on points as mine objects are. Is this the main reason or am I using the redshift instance wrong? I'm not using his workflow, i import each .rs file on separate nodes. Thanks for any help at all I want to optimize my scene, but unsure if i need to reduce my points on each obj/rs or if i can do something else to reduce rendertime. SCENE FILE: redshiftProxy_v01.hiplc
  14. Redshift Object Id's

    Hey All, I'm trying to figure out why I can't get Redshifts puzzleMatte AOV to work.. I understand the workflow in Redshift for Maya, as its pretty easy to set an objects ID.. where as in Houdini I'm not quite sure where to set the SOP's object ID. I've even tried Material ID right in the RS_Material node and still no dice. What is the proper workflow for something like this? Do I create a wrangle and set the ID in there? or is there some sort of parameter that i need to create in the interface? The issue is I'm not sure what variable (if it is at all) Redshift is looking for on the points? prims? detail? I'm a bit lost, and there doesn't seem to be any tutorials or posts about this! Cheers, -J
  15. What's the latest Houdini + RS versions people are successfully running? For me it's Hindie 16.5.439 + RS 2.6.12 (built for Hindie 16.5.268). Any more recent production or daily build of Hindie doesn't launch on my setup (Ubuntu 18.04 + Nvidia TitanV GPU) and any more recent RS version simply won't render. Get strange results in RS Renderview especially.
  16. Hey all, I have started using redshift a few months ago and so far i like it a lot.! I currently have one 1080ti 11gb gpu in the machine I am using it on. Would like to get either another one of those cards since the gpu prices seem to have dropped lately back to something more reasonable, or get 2 1070ti 8gb cards. I have heard that the performance diff is only like a 20% gain for the 1080 over the 1070's, so might be better off with getting 2 of the 1070's. The main question is though, what happens when you hit the render button on your redshift node for a sequence inside houdini if you have more than one gpu.? If I had 3 gpu's, would it automatically render frame one on the 1st gpu, frame 2 on the second, frame 3 on the 3rd and so on..? Would it render the first frame across all 3 cards simultaneously by breaking up the frame to submit to the different cards, is that even possible.? Do the extra gpu's only get used if you use a distributed rendering software like deadline or by launching RS renders from command line.? It seems like you have to launch from command line in order to get the other gpu's to render, but I have never worked with a machine with more than one gpu installed. If I were to submit a 100 frame render from within houdini by clicking the render to disk button on my RS node, would it only use the main gpu even with other gpu's installed.? Any info from artists using multi gpu systems would be great. I didn't find a lot of info about this on the redshift site, but might not have looked deep enough. The end goal would be to have the ability to kick off say 2 sequences to render on 2 of the gpu's while leaving my main gpu free to continue working in houdini, and if its time to end the work day, allow the main gpu to then render another sequence so all 3 cards are running at the same time. I will most likely need to get a bigger PSU for the machine, but that is fine. I am running windows 10 pro on a I7-6850K hex core 3.6ghz cpu with 64gig ram in an asus x99-Deluxe II MB if that helps evaluate the potential of the setup. One last question, sli bridges.? Do you need to do this if trying to setup 2 additional gpu's that will only be used to render RS on.? I do not wish to have the extra gpu's combined to increase power in say a video game. I don't know much about sli and when/why it's needed in multi gpu setups, but was under the impression that is to combine the power of the cards for gaming performance. Thanks for any info E
  17. Greetings on behalf of the Principium team! We are a group of seven third year students from NHTV University of Applied Sciences in Breda, the Netherlands. We have been working on this cinematic short film project for 19+ weeks, from it's conception and storyboard to the stage you see now. We hope to complete and release this short film in July, 2018. We're using Houdini and Redshift for Houdini for various effects in the film, some being crucial narrative points, and others being to add juice! We want to bring you along on the last two months of our project, and share our progress as we near completion! Feel free to give any feedback or comments, we look forward to hearing from you!
  18. I’ve got a simple voronoi fracture sim with added edge detail (from Jonny Farmfield's example). An object from two Boolean’d spheres falls and breaks on the ground. Everything is working great except I can’t figure out how to get my RSNoise bump texture to stick to my fractured pieces. I’ve tried to do everything suggested from my search results, but it’s not working. I tried to create a vertex UV attribute as well as a rest SOP to no avail. I’m quite certain it’s something simple. Always is. On a side note, I am creating three point attributes from boolean and fracture groups to pass to my redshift shaders, inside, outside, and ainsideb. This works great and is picked up by RS even though I’ve not specified that the attributes get passed through my assemble SOP. When I do pass them though explicitly they get all jumbled up and don’t correspond to the right points anymore. Does redshift just figure out these attributes on it’s own. They aren’t even listed in the Geometry Spreadsheet yet work correctly. I didn’t want to assume this behavior as it might be messing up other attributes needed for the noise to work. I’ve attached a file. simple.edge.displace.v7.hiplc
  19. Hi ! I am working on RBD in Houdini 16.5.268 and I render it with redshift 2.5.56 I have some problems during the rendering : we see the edges of the fractures ! I tried a lot of things without managing to get rid of it. It works fine in mantra, no artefact. My geo has UVs, Normals and rest position. Do you have any idea of how to correct that please ? Scene is attached and some pics of the results. PS : I also had other problems while rendering rbd in redshift. In some scenes, applying two different materials with different displacement values on inside and outside groups of an object results with a gap between inside and outside faces. In other scenes, the displacement of inside surfaces flicked. It seemed that it was moving along time, I didn't find out why. I read the redshift documentation and watched several tutorials but maybe I don't work the correct way with displacement in redshift, could someone help me ? Thank you very much ! Have a good day ! no tessellation no displacement tessellation no displacement no tessellation displacement tessellation displacement mantra displacement material MAT_prob_v01.hipnc
  20. REDSHIFT AOV EMPTY

    if I render with redshift my aov are always empty, whether zdepth, gi, diffuse raw....
  21. Redshift_Mesh_Light

    I'm practicing on Redshift from Rohan Dalvi tutorials but i stuck where he using geometry light or known as Mesh light, it doesnt work for me the mesh is there and linked with the RS_light node but nothing happen
  22. Hi guys , Recently I followed some tutorials and made this guy. but when I start render at Redshift, It is too thin that I can't see. Just like this T_T When I rendered it in Mantra, It looks like has thick wire rightly, but I don't like this look. So I wanted to render this man in Redshift and looking for some clever guys giving me some tips about it. Sorry for my poor English ! and Pleas help me ! Thanks for read and have a good day
  23. My houdini version is 16.0.736 ,I read the official document the plugin 16.0.705 can compatible with Houdini 16.0 version 705 and above. But I failed. Just like this.

  25. Hey magicians, I'm trying to render millions of particles, I'm using a method I saw in Peter Quint videos using the wedge rop, my issue is when I load lots of instances, pc gets super slow. PQ recommends to use packed disc primitive to avoid this, but when I use, I can't read attributes other than P on the instance redshift, so I can't apply things like motion blur. Any recommendations to solve this? Thanks!
