  1. Redahift Z depth

    Hi I'm trying to render Z depth for a smoke in Houdini via Redshift, it's look like working fine with object, but somehow not working with a Pyro smoke. It's look like Redshift doesn't "see" the volume, any idea why? Thank you
  2. Shading Techniques III

    Check out the course at: https://www.cgforge.com/course?courseid=shading-techniques-iii Thanks for watching!
  3. Hi guys! I installed Deadline recently and normally I have a multiple RS Rops where I define the render folder path with a string parameter in a null node. The thing is when I submit the render job to Deadline with the expression that I use for output I'm getting this error: (Syntax error - extra tokens detected in expression (/out/Redshift_ROP_HQ_PMs_DWAA/RS_outputFileNamePrefix)). I 'm defining the folder paths in the null like this: $HIP/render/ And the rest of the expression on the RS Rop is like this: `chs("../RENDER_PATHS/render_folder")`$HIPNAME/$HIPNAME.$AOV.$F3.exr Somebody knows how I have to change the output expression in order to get the render correctly? Here is a screenshot from the expression: Thanks a lot!
  4. SBSAR Files for Redshift

    Hey party people, Has anyone developed a solid worklflow for getting .sbsar files to work with redshift inside houdini? Did some research on it, but it seems like I am not the only one struggling with it! Excited for your opinions Cheers, Felix
  5. Hi guys! I've been hitting this wall project after project. I am not good at scripting, but i was wondering if a script or a function could be done, or if it's a crazy idea. Well, usually when I recieve a model from a modeler, the guy has already assigned materials to the model, that houdini will read like shop_materialpath. Ok, now, if the model has 10 or 20 different shop_materialpath, it's really painful to check 1 by 1 the names and make 1 by 1 the shaders with the same name under the mat context. Do you think there is a workaround in scripting to make this process automatic? What is your workflow about this subject? Have a good day guys, if I get anything working I'll post it here, since I think it could be a really cool tool for everyone!
  6. Houdini Redshift build advice

    Hello wizards, I am about to build my first PC ever, I have no clue on hardware specification stuff, I have like $3000-$4000 budget and I want to invest my money wisely that's why I need your help. I would use this PC for Houdini and Redshift mainly, mostly motion design and a little bit of simulations, and i want to be able to upgrade this setup overtime. I also dont know if I am missing something important. This is what i came up with: Processor AMD Ryzen 9 3900X, S-AM4, 3.80GHz, 12-Core, 64MB L3, con Disipador Wraith Prism RGB Motherboard Gigabyte ATX X570 UD, S-AM4, AMD X570, HDMI, 128GB DDR4 for AMD RAM Corsair Vengeance LPX DDR4, 2400MHz, 32GB (4 x 8GB) GPU: Gigabyte NVIDIA GeForce RTX 2080 SUPER Gaming, 8GB 256-bit GDDR6, PCI Express x16 3.0 HDD SSD Samsung 860 PRO, 2TB, SATA III, 2.5" Liquid Cooling Raidmax TORNADO RC240 Case Corsair Carbide SPEC-054 Power source Corsair CX750M 80 PLUS Bronze, ATX, 120mm, 750W I appreciate any tips!
  7. Hi all, Excuse my lack of understanding, however I have attempted to google with no avail. I have an alembic file that I've imported however I cannot for the life of me work out how to assign/apply a material to it - using the material node doesn't work. I've read about unpacking or converting the alembic but this doesn't alter what I'm seeing on the render. There must be a simple solution? If it helps, I'm using Houdini 17.5.173 and Redshift 2.6.41. ~ If anyone has some ideas please comment! Thanks
  8. What should I do to move houdini particle attribute(ex: motion blur, pscale) to maya redshift? I made particle in houdini to rs and moved it to maya redshift
  9. Hello! I want to change Redshift 's emission weight parameter by attribute, but this parameter does not have input to connect it. So, I tried to create attribute of the same name of the parameter , which is emission_weight, but it does not override it. Please help me!
  10. Hey guys, I need to send a large point cloud which instances geo to the cloud to render. The problem I'm having is the instancefile attribute is absolute, and once the project is uploaded to the cloud render environment the path is no longer relevant/correct. Redshift does not seem to expand strings at render time, so $HIP or $JOB do not get evaluated afaik. I've also tried setting the path to a node within the .hip file. For example, this will work: M:/_Work/_Personal/sandbox/rs_proxy_relative/rs_proxy/teapot.0001.rs But this will not: \$HIP/rs_proxy/teapot.0001.rs Nor will this: /obj/teapot_rs/OUT/ I've attached a super simple setup where I get instancing working using an absolute path (it references the output of the RS Proxy Output SOP). Is there any way to get Redshift to to instance from a path that is relative to the project folder, or a node within the .hip file? Or has anyone had experience getting Redshift instances rendering on Gridmarkets? Thanks all! Note: I've also tried using the instance obj node (see v002 hip attachment). BUT the issue I run into with this is it maxes out my GPU's VRAM at render time, whereas using an absolute path with instancefile renders just fine with the ~6m points I need to instance on. rs_proxy_relative_v001.hip rs_proxy_relative_v002.hip
  11. I am reaching the final stages of a personal project of mine and I was wondering if this render times were okay for the setup I have since I swapped to redshift 3 days ago: 1070 ti 8gb ryzen 9 3900x 32gb ddr4 3200mhz It takes 40 to 50 minutes to render the following (no DOF nor mortion blur): NOTES: The scene consists on bolts and sparks with incandescent material + the emisssive sword, 2 Volumes (you are looking at the smallest one which is around 8million voxels) + 3 mesh lights inside the capsule (bolts, sparks and a scorch on the impact area of the bolt) and 3 others spread around the scene (the Highlighted ones) EDITED: NOT EDITED: These are my settings: In all mesh lights I copied the override sample values because I dont trust it xd and all have 64 bounces for volumes too. I hope more experienced artist can help me out with this one if you find something odd in my project. As always, thank you very much EDIT: No, I wont be using the Optix denoiser and this is how the noise on my scene looks:
  12. Brand new to redshift and am trying to recreate something that seemed to only work in mantra. Basically just want to take a heightfield and control the materials on the heightfield with a layer mix per each element (debris, bedrock, etc.) which was easy enough to do by binding in the attributes as the bias. I've been looking around and it looks like instead of a bind you need to use a pointlookup and there are a few different substitutes for the layer mix in redshift it seems. Simple sample file attached. Why doesn't it work? RSPointLookup.hiplc
  13. Good day to you Houdini magicians out there! I have been following the Particles IV Tutorial by Steven Knipping (the one with the cherry blossom petals) and as i did with the previous tutorials i always found a workaround to get it to work with Redshift... except for this one and it makes me go nuts. On the surface level everything is working as intended, except for the materials. I've tried applying the shaders on the actual instancing items, even stuff like applying the material onto the instance itself.The materials are also set up to read the Cd attributes and i checked that the Cd attribute isn't replaced or erased somewhere. Can somebody help me? Did someone out there stumble upon the same problem and found a fix. If needed i can provide the .hip file. I know it's not a too big of a problem but it's bugging me really bad. I am thankful for every bit of help!
  14. Hello! I need some help to understand how to use some string expressions, I'm using Redshift ROP and I want to change the render paths on some AOVs using the Custom File Prefix from each AOV. I want they will be saved on the same folder like the main output path but with other names. So, I'm using this string for the main render path: RS ROP output file name prefix: $HIP/render/$HIPNAME/$HIPNAME.$AOV.$F3.exr And I was trying to use this expression for AOV custom path: `${chs("RS_outputFileNamePrefix"):h}`/BumpNormal.exr Because I saw in this link that this expression should return the directory from the entire string without the file name and extension but I'm not getting the file directory using this expression like this. In conclusion, I'm looking to set the render path only one time and the AOVs with custom path can load it and use other names or formats. Thanks a lot!
  15. I am tring to assign either .tiff or .rstexbin files to my character that i am using for RBD. when i assign the textures to the character, they seem flat even though i assigned the displacement map. The character have at least 4 UV sets per texture it seems. is there an easy way to create all of the groups needed since the character has at least 12 different objects that were merged together before being packed. I unpacked the geo and could se the uv sets that were all layered on top of one another. i have 25 different texture maps and i am having to select the polygons individually and then group them to use a material sop to assign to the group. if there is an easier way about this please let me know. I have attached url for the textures and the hip file. https://drive.google.com/uc?id=1mjLxLb2AWJcL2qAZTXe0fIVlP860Ku78&export=download DinoCharacterHelp.v01.hipnc
  16. Hi all, I'm very new into Houdini, but I'm loving it. There are certain things that they must be quite simple to do but I'm not finding the way. This is importing a png sequence to use into the diffuse channel of a Redshift material. If anybody can help it'd be amazing. Cheers, Sebastian
  17. Heyo guys (and gals), I've run into a slight problem setting up my new workstation in that Redshift does not seem to be working properly. I am able to search for all the Redshift nodes in Houdini and even place down some of them (mainly the Redshift IPR node in ROPS) but for the wast majority I get this kind of error: The attempted operation failed. Invalid node type name Traceback (most recent call last):File "Redshift", line 1, in <module> File "/opt/hfs17.5.460/houdini/python2.7libs/roptoolutils.py", line 9, in createRenderNoderop = hou.node('/out').createNode(rop_type, exact_type_name=True) File "/opt/hfs17.5.460/houdini/python2.7libs/houpythonportion/ui.py", line 850, in decoratorreturn func(args, kwargs) File "/opt/hfs17.5.460/houdini/python2.7libs/hou.py", line 8586, in createNodereturn _hou.Node_createNode(args, kwargs) OperationFailed: The attempted operation failed.Invalid node type name So seems to me like Houdini has access to create the nodes but is missing the definition for the nodes (in laments terms). Anyone encountered something like this before and have some advice on how I can fix it? Any advice is greatly appreciated. Thanks for the read! Stay safe out there!
  18. Hi guys, I'm pretty new using Redshift as an render engine and I have a problem that I know how to solve. I've created a large column of red smoke, but when I render it always appears an annoying shiny noise. I've tried to increasing samples of all the lights to 8192, the gi sample have the same value and I've also override the volume samples to 16384. The uniform samples are: min samples 16 and max samples 128. What can I do to clean up the render? I've tried to increasing the uniform samples but doesn't seem to show any change and increase the render time a lot. I've attached and image to show you this shiny noise on the volume. Thank u in advance!
  19. Hey guys, I try to export particles to maya with a redshift proxy but when I try to export it, the proxy appears empty. I tried using both the Output Proxy Sop and the Redshift Rop and both give the same result. Is there anyone who know why this would happen ? Cheers,
  20. Hey guys. Any idea how I could get render time displacement, based on values of points that I scattered on the surface? This is a simple scene of what I`m trying to achieve. Basically I have sourceprimnum and uv values on points and I just need to transfer those values to UV maps I think so I could use them in redshift to drive displacement. I tried using geomerty to bake displacement maps in COPs and it works, but original geometry is would have to be subdivided too many times and would get way too heavy for what I`m after. Any ideas how I can do that in render time? I`m gonna use Redshift, but that doesn`t really matter. Cheers Janis displacement2.hip
  21. Hey Guys, after adding a RS camera tag to my camera in Houdini. My ocio fails, it worked absolutely fine before I added it. Plugin Version is 3.0.13 Houdini Version 18.0.0287 Hope somebody can help me, cheers, Lucas

  24. Hello Peoples, its my first Time typing in a forum, but i am looking forward to meet the right people here, because in my social area nobody wants to speak with me about Houdini. Haha. As the title says, i want to know how i transfer the pressure/stretch/bend attribute to the final Render Geo and make the Stiffness or the Stress visible in my Rendering. Has anyone a clue? And sorry if there is a topic already. Thanks very much
