Hello, I have a few questions about vop nodes in mat context. I have no trouble with vops in sop, but things seem to fall apart in /mat (FYI I am working inside a material builder). 1. Is it possible to access @ptnum and @primnum? It doesn't seem to work 2. Some binds just don't seem to work. If I do the same bind in /obj vop context, it works perfectly, but binding it in /mat material builder doesn't. Why would it not work in the /mat context when the nodes are the same? 3. If the vop asks for a file and I use op: to get data from a node in /obj, it does not work and says error finding geometry. But if I do the same thing in /obj in a vop network, it works perfectly fine 4. In /obj in a vopnetwork, you can access the input from the geometry vop global parameter node. If the vop node asks for a file, you can wire it into opinput 1. How do you do that in /mat? What if I want to access the geometry to which the shader is applied? It's asking for a file, but I just want to use the geometry to which that shader is applied. Thanks

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 first image is my failed work, I just want to get the second image result. but it clearly, I failed... I only get the first result.

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/OUT op: "/obj/copnet/OUT" "op: /obj/copnet/OUT" op:`opfullpath('/obj/copnet/OUT')` and many other mutations of the same thing. anybody? thanks, D. file attached just for case copReferencing.hiplc
