  1. Is it possible to use point normals for displacement shading? I'd like my grid to displace in the same direction as the normals are in this video. Houdini Tutorial #7 (Point Normal) - YouTube
  2. I would like to take this value out so I can create a colour gradient out of it and use it in my texture thereafter. I know how to do it with the stress attribute as it appears in the constraints attributes, but I do not have a Bend angle attribute in my solver. Cheers!

  4. Hey everyone, so I've set up a scene with a principled shader and it rendered fine when I exported it to ifds and rendered it on our farm. But then I needed an extra AoV for an attribute to mask out parts of the object that has the shader assigned. In order to get that to render, I opened the principled shader and did a simple bind->bind export setup for that variable which then rendered fine locally. But from then on, no matter what I tried when exporting the scene to ifds, the object with the open principled shader would always render as if it has no material assigned. I tried forcing VEX shader embedding, which made the ifds quite a bit bigger and made me hopeful, but to no avail, all I get is grey shading. For now, I render the mask as a constant material in a separate mantra node but there has to be a way to output an attribute in an AoV when using the premade shaders. Any help is very welcome!. Thanks in advance, Paul
  5. Hey guys. This shading effect was originally made on Redshift. Does anyone know how to achieve the same effect on Mantra? . I’m new to Houdini and this is way beyond my knowledge. Any help would be much appreciated. Here's the hip file just in case. LiveScalingBulletsSetup01.hip
  6. Hello and welcome to this post. Synopsis: In nature, we see a phenomenon called tropism (the way a leaf orients itself towards the sun). I need help building a rig that will simulate this effect. These are the objectives: Create a source object acting as the reference point for tropism Get the leaf to orient itself in relation to the source Additional challenge: It would be ideal to shade the front and back face of the leaf with a different texture. What is a neat VOP setup which would simulate this? Here is a basic HIP file to begin messing around with. leafShading_Orient.hipnc
  7. Building a fur shader

    Just out of curiosity, can I build a fur shader using VOPs? https://www.sidefx.com/docs/houdini/shade/build.html
  8. I saw this video where you can turn geometry into displacement. https://www.youtube.com/watch?v=rwzo8LD4Tac I want to know how I can turn modeled geometry into a displacement shader. I'd like to turn the modeled geometry on the right into parameters for a displacement shader for the plane on the left shown in the picture.
  9. Hi everyone, so I have been working with some renders of particles that have a material assigned to them with 0 opacity. The problem comes when I try to render out as well a Deep Camera Map and bring it to Nuke. Using the usual workflow with deep images, I am able to see the particles only when I use the DeepToPoints node in Nuke - prior to that I don't even get an Alpha nor I can see them. Is there any way I can export a map for the deep so I can make holdouts with this? Thank you!
  10. Shading Techniques III

    Check out the course at: https://www.cgforge.com/course?courseid=shading-techniques-iii Thanks for watching!
  11. Hi everyone, did a pyro sim along with a collision object. When I up the density from 1 to 4 in the pyro shader, the voxels are getting visible (attached an image to the post showing the issue). Is there any way to prevent that or soften the voxels on the outside in a post process or something? Cheers, Christian
  12. Hi people, Disclaimer: I'm pretty new to houdini and I'm probably using it in a way more basic way that most people. I really like the basic Color SOP node, using that to apply a color to geometry. However, if I want to apply a texture map to geometry, I've been using the UVQuickShade SOP. My question is - if create two cubes and apply a color 1,0,0 using Color SOP to one, and I apply UVQuickShade using an image that is constant color 1,0,0 to the other, why do the two cubes look different in the viewport and in renders?

  15. Hello, my name is kalata and I am an experienced Houdini Artist. I also have solid experience in 3Ds Max, Nuke, After Effects and Photoshop. You can check my demo reel here: https://www.behance.net/gallery/96292145/Procedural-Apartment-Blocks https://www.behance.net/gallery/93554753/Procedural-Neighbourhood-Generator
  16. Hi, I try to offset a texture with a For Loop in a shader. In the example file you can see I iterate 5 times and offset the texture 0.1 units with each iteration. Is it possible to combine all of the iteration steps and show the result of that in the rendered image? Like in the attached picture where I painted in the desired result with red. kind regards Jon forLoop_VexBuilder.hip
  17. Hi Guys, is it possible to go ROP > COP > ROP I have a displacement from COP {noise} baked to texture, I would like to shading Color based on P.y but after displacement. Is there a way? I basicely using the same noise for Cd as for Displacement just shifted with ramp into some colors. The only way I found is "ramp from attribute" {from displacement Cd} and than take it back to COP and write textures. But the color is point color so I have to subdivide the mesh way to high.

  18. Hello, Here is short video showing how volumes can be used to shade and texture semi-translucent organic things. Volumes For Organic Assets This approach allows to achieve close-up realistic organic look for semi-transclucent assets where SSS or colored refraction is not enough. An object with UV's is converted to signed distance volume with UVW grid. Then volume is used to set density and perform uv lookup in rendering. This way density can be adjusted by depth. I.e. not so dense near the surface and very dense at the core. Or not very dense, then dense patch like island of fat, then not dense again. UVW grid is used to texture volume. Different textures can be used at different depth. This approach allows very flexible yet powerful way to place any texture at given depth. Texture X at depth Y. I.e. big veins are 5mm under the surface. This approach is best for close up organic hero renders where SSS or refraction are not looking good enough.

  19. Material Builder to Layer

    Hey guys, I'm trying to get a custom material to export a layer properly so I can combine other shaders. I've attached the .hip file below. This is the material I built. As a simple example, it works as intended. However, there's no layer yet: So, I dove into the principle_core shader and was able to (unsuccessfully) create a pbrdiffuse node, plug that into the layerpack and then export the layer for mixing: But unfortunately when I assign the layermix to the object, I lose the ramp. It seems to take just the first input of the ramp: It's probably very simple, but this is driving me crazy. Any ideas? material_help.hipnc cw
  20. World Space Position?

    Hi everyone, I've got a problem that has me stumped. In my setup, I'm flying with a camera through a volume that has its density modulated via a couple of noises in the mat context. But whatever I do, I'm unable to make the noises stick to their position, it seems like the P attribute from the globals node is always in camera space. I must be missing something obvious since a lengthy internet search didn't give me any meaningful results. I've attached my file, to observe the problem just render a frame and then jump to another frame, the camera will have moved but the noise pattern is in exactly the same place. Thanks in advance Paul world_space_noise.hip
  21. Hi all, I am working on a project that has pages of a book flipping with camera on top. Audience will be able to see the content on pages. I have already created animation of pages flipping. Problem is to assigning 10 different / unique page texture content wise to 10 pages of animated book. What is the best solution to do that. I am using copy and transform to define no of pages. Any pointers will be helpful. Thanks in advance.
  22. Check this out guys: The bumps on top of the tentacle are done with displacement. In fact the same displacement map across the tentacle. How can it be, that the amount of displacement seems to be inverse to the thickness of the geometry? I would expect the displacement to be uniform across the geometry, regardless of the geometry on which it sits? Can anybody make sense of this for me, please?
  23. Hi, is there a way ro reach texture from Agent materials? opdef:../..?clothing_`padzero(3,ch("../../texture"))`.jpg I need just slightly edit it... Thanks BK
  24. Hey! Could someone help me understand this? I have noise going into the vector displacement of a principled shader. Why do I have change the amplitude of the noise in z-axis to affect the y (up/down) position? If I do the same at sop level I can just adjust the amplitude in the y value. I tried messing around with the transform vop, but I didn't get anything working. Thanks displace.hiplc
  25. Looking for a way to apply a flat and fast shader to particles and also be able to control size, color and opacity over life as you could do with trapcode particular after effects plugin or x-particles. Thx!
