Hi, I've some experience with VEX in SOP land but I'm new to Mantra shading and I want to get better at writing vex shaders. What would be the modern way of doing that? In particular, I'm not entirely sure if I could simply write my code and hit compile (the way I would with OSL in RenderM...

Hi. Is any variable that stores information about wire existence in shader editor? I mean, I need the variable that is 1 when the texture is connected to base_color slot and 0 when there is not. What I'm trying to achieve is the arnold texture preview in the viewport. I created a texture t...

So a few older tutorials I have been following have people dragging the Checkerboard from the Material palette onto an object. I thought maybe the checkerboard just was no more since the material system changed, but I recently saw a Houdini 17+ tutorial where someone did the same thing. My material... -
Help a brother out, I'm getting headache by trying to figure this out. At this point assuming it's a limitation of the software. I've been getting more into procedural texturing and shading and sometimes want to blur those textures for example to use as a mask. This far I haven't been able to fi...

Hello! I'm trying to control frequency of Cellular noise with distance from the middle of the UV map. There is some weird distortion on the noise, and I'm quite sure now my whole approach to this is wrong. Any ideas how this could be achieved? Thanks in advance cell_noise_freq_by...

Hello, Everyone. recently I meet a challenge: is how to let a lot of textures in the different grid, and it does not have the same one. I tried to input the stamp value to MAT or SHOP, But it doesn't work. If anyone knows how to fix that, please help me, I will be deeply grateful. 1. The firs...

Hi, probably very stupid question and basic, but can't figure it out by myself and internet... How to bring Material from "Material Palette" to a "Shop" ? I want to take "Principled Shader" and other shaders to Shop... Hope Its clear. Bretislav

Hi, can anybody confirm or invalidate my suspicion that op: expression in shaders context (mat or shop) cuurently doesn't work? I know syntax has been a bit inconsistent between different Houdini versions but right now in 16.5 it doesn't seem to work at all for me. i tried: op: /obj/copnet... -
I want to make a shader using attribvop or, simillar shader thing in SHOP. I made simple hip file and attached. If you guys have time to answer, thank you all shopTest.hip

Hey Guys, Im working with a particle simulation and I cant seem to figure out how to get the colors generated in the particle sim to apply to the shader being applied to the instanced geometry. Any help would be awesome. OT111_0010_glitter_v001.hip

I have primitive groups set up in SOP level, something simple like a box with a voronoi fracture applied with the inside and outside primitive groups. How can I access this primitive group in shop context? I am trying to compare whether or not a shading point belongs to a specified group so I can cr...

Hi, just a quick question: some SHOP nodes have a geometry input. like pcopen, intersect, etc. I'd like to point these inputs to the geo node existing in the scene rather than file on disk. Same thing like bringing in the COP result into the shader by typing `op: obj/copnet/OUT`. But it seems t...

Hello i think it must be a general question, but after many tests, I have achieved nothing, so in geo context i have Cd attr (red color on box) How import color into my material vopshop network the final image should be a half red/white cube in attached file simple example of what I mean...

I have a question about noise texture I use rest POS to give noise material If the size is very small there will be flashing Now I don't know how to solve, Or other way to make this kind of small dot I hope that the master to help me rest noise.hip

Recently I am using quite a bit the amazing inline and snippet vops in shop context to write volume cvex shaders. Really amazing stuff cause I can pretty much copy and paste the code from an Attribute / Point Wrangle node in sop context. Question 1: what is the difference , advantages , disadva...

Hi guys! I got 2 questions for, I think, advanced Houdini users(or for everyone else). I've created standart material in SHOP(Clay, for example), and I turned to OpenGL tab. I want to see as many graphic information as it could be done. So, I set normal map texture in its field - and noth... -
Hello. I tried to search in this forum but I found no answer. Some tutorials in which they use Houdini 12 they have an element in the Material Palette called "Reflective". In Houdini 13 this doesn't exist anymore. Is there an equivalent? Thanks in advance. -
Hi all, This is a double post from the official forum because I got no response after one week there. I want to make a custom SHOP in HDK. The SHOP should be able to accept a series of custom VOP (limited in this context) and retrieve the information from the network of children VOP. Then...
