redshift Rendering Ramp Color created in VOP in RedShift
MantaRay posted a topic in Lighting & Rendering
Hello. I tried to render the color ramp I made in Vop with RedShift, but it doesn't work.The red attribute vop in the attached hip is the one. I'm still a beginner in Houdini and don't know much about RedShift render, but I was wondering if you could help me. Apply ramp color.hiplc

Hi all, First of all, please let me know if somebody else asked this question and got an answer, I looked for an answer here and didn't find any, someone has asked on SideFX forum but nobody answered. anyway, I have a scene with hundreds of thousands of points in it that I wanna render as instances. It works fine when I render with Mantra, the @instancepath attrib works just fine, and it does work with Redshift too but it's very slow and it just freezes when the number of points goes up, even 1000 points would take forever to render with RS. So I was wondering if I'm missing something. Thank you, E -
Hello all, I’m a relative noob and while this seems like it would be do-able, I have no idea which nodes I would need to invoke. I would like to map a repeating (but not tiled) texture on an object that already has an underlying material / texture. (So for example, knots on a tree trunk, or pimples on a human face.) The way I imagine this might work is that once I’ve used Scatter SOP to scatter some points on my base object, I would somehow translate those point coordinates to UV coordinates (Not sure how to do this). Those UV point coordinates could then be used along with a texture’s 2D matrix to map its pixel data per point (Don’t know how to do this). I would also imagine I could use a pscale value with some randomization to vary the sizing of this repeated texture (again, not sure at all how to approach this). I'd also imagine I'd want to use some kind of multi-layered shader with alphas in order to preserve the base layer material properties. I should note that I’m using Redshift here, as I imagine this might make a difference as it might have a few more limitations compared to native Houdini texture/materials workflows (though maybe not?). Preemptive thanks to any responders! NpF -
I would like to have light 1 from frame 1 to 10 and light 2 starts at frame 11 for example. Cheers

Hello, Any idea why the Redshift camera option 'enable photographic exposure' doesn't show in the Houdini default render view? It shows in the redshift render view, but is gone when I export. cheers

Hi Guys. I downloaded this FBX file a while back and it's been great. It's a Mark VI ship that's textured. I brought it into Houdini and mantra reads it well. The only problem is I'm using Redshift for the scene with water and I'm not sure how to get redshift to read the shaders or how to connect them. I can't seem to find any useful tutorials on this either. A couple years ago Grand Master Atom was amazingly helpful with a script that he wrote for redshift to read downloaded shaders but I can't get that to work anymore. I think the recent updates over the years broke that script or something. Anyone know how to connect so redshift reads the shaders? Pierre Mark_VI_Patrol_Boat_Dirty.hiplc -
Hello magicians. I want to share with you the result of studying l-systems. Behold the Moss Incredible aka Sphagnum! Redshift shading. And yes, it is growing. Available on https://gum.co/fZROZ https://gum.co/qmDmg Thanks! akdbra_moss_grow.mp4 akdbra_moss_var.mp4

Greetings all! I’d like to know if it’s possible to pipe any one of the Maxon/Redshift noises into a SOP node in order to displace geometry on a mesh (rather than having Redshift handle the displacement at render time). I need to do this for the following reason: Maxon/Redshift has the specific noise I want (don’t want to spend a lot of time trying to replicate or approximate using one of the SOP noises). I will need to generate vine growth along the object I will be displacing with noise, so unless I’m mistaken, using render-time displacement is not an option. If there’s some workaround to this I haven’t considered, please enlighten me!!! Preemptive thanks for any responders! NpF

Hi all, i'm trying to render volume with redshift but my render look lowres compared with the viewport on the left. Could somebody please help? Thanks! nebulaR&D_v01.hiplc

Hello guys, I have this Bendangle attribute that I am using as a color in my redshift material. I don't have any issue when I convert it to a Cd attribute and then use the RSUserColorData vop node, but because I want to import two attributes, I couldn't convert them both to Cd as I would have two different attributes with the same name. So I am feeding my attribute (RSPointAttribute) to a RSColorConstant to my material and this happens (screenshot). this effect turns up. What am I doing wrong? Tx

Hi ! We use redshift for render and everything is ok, but We'd like to use some machines without GPU to simulade DOPs or generate geometry in Hqueue The problem is that since these machines don't have GPU, they obviously fail to load redshift dlls and OTLs. Hqueue gets an error and fails to process this hip file. None of redshift OTLs is used or involved in simulation somehow, but hqueue fails anyway just because some unknown operators present in scene. I used to solve this problem in linux by installing some nvidia libs into system, but i can not solve it under windows this way..... And the question is : Are there ways to force hqueue to ignore this type of errors and process hip file any other advices will be appreciated thanx in advance!

What should I do if I want to combine color and attribute in rs mat? Like using bind in mantra The first one was done in mantra, the second one in rs, but I can't do what I want

Hello guys, You see in every tutorial how to remove noise on a render by adding more pixels per samples. I like noise, but I only want it on the background lighting and not on my geometry. How can I do this? Cheers!

Noob question XD Like when I manually create some attribute for the shader, @emit @brightness @width or other attribute, how can I transfer these attribute to Redshift ?

Hello, I am just starting with Redshift within Houdini and I have gone through the basics. I have a sim that I exported as an alembic and I used the unpackSOP to recover my point attributes and prim groups, all on the same mesh. How would I go about applying a different colour or texture on those groups. How can I use the point attribute to drive a particular color? Thanks a lot

Hey guys, i have a question regarding redshift instances on high particle counts stuff rendered with redshift: Everything is working well with a "s@instance=..." wrangle. Then if i try to get the Cd attribute to change the instances/particles color it get super slow, is it a normal behavior or is it somehow a way to avoid it/doing it more efficiently ? For example if i don't use instances but standard redshift particles, even with changing the Cd in the shader it is super fast, it only happens when instancing.

Hi guys, I have a magazine prototype I've put the front cover on using a redshift texture sampler. I can't find out how to make the material respond to light though - it stays the same brightness no matter what. This is probably a very silly, easy to answer question but I can't make it work...still inexperienced in all this. If anyone has the answers please let me know!

I need to get clean glowing Volume Lighting AOV in Redshift. First attached image is what I have in renderview - it's precisely what I want. Second one is what I get once I have my EXR. I dont need all this smoke. How do i fix it?

Hey guys, help me out. I, for the life of me, can't figure out what's wrong with my render options. I set up my fire the way i want it to. Viewport looks nice. Then I try to render it as PNG and get this ugly result. What should I check? My Volume option for lights is on. Global Illumination is Brute Force.

Hi, I'm trying to render the deep aov with redshift, but when I export it as an .exr in nuke through the deepread node, it says that I don't have any data regarding the deep layer, when I render the pass in Houdini it's just black, but it should somehow get the informations about the geometry location in viewport, am I missing something important related to the camera or the objects/matte exclusion in the redshift rop node?

Hey guys! I'm trying to setup deadline for a couple of machines for rendering in houdini with redshift. Deadline setup is ok. Caching and mantra rendering jobs finished successfully. When it comes to redshift job, deadline also receives it and distributes. But the rendering process happens very fast and there are no render output files in the output directory. Also while deadline saying that the job is rendering the video card doesn't seems involved. Did anyone have a chance to encounter such kind of problem. Any help appreciated.

Hi, i've been trying to export my fur from Houdini to be rendered into maya with redshift through rop alembic, but when I cache the nurbs they don't render at all, so I tried to convert the fur with a polywire and exported in fbx. It works, but it's still a polywire, what am I supposed to do to maintain the original fur? (Tried to install redshift in Houdini for a proxy export, checked the .env file with the correct path installation, but the plug-in won't show off in the houdini shelf). Should I try to cache in bgeo and make the hairgen a digital asset with Houdini engine or there are other ways to make this work? I'm using Houdini v. 18.5.408 and redshift v. 3.0.31.

Hey guys, I have a very strange behavior with Redshift Motion Blur, some frames are rendering correct, and some are not. The interesting thing is, when stopping butch rendering and rerender frames with mistakes, they are then correct, but frames that were correct could have this issue again. I tried everything, but no successes I have Houdini 18.0.391 and Redshift 3.0.20 Please download Hip and the Zip file with Frames to see what I am talking about. Hope that someone could help me with that issue Thanks a lot Maksym Particles_Redshift_MotionBlur.hiplc Particles_Redshift_MotionBlur_issues.zip
