Hscript Instances + Shader Defined In Otl

[hoknamahn]

Hey guys!

Maybe someone knows is it possible and how to solve this problem. I have some custom SOP and a shader defined inside it. I'm trying to use HScript Instancing to instance a bunch of that SOPs. All parameters which I pass as point attributes works fine excepting one - the name of a shader. I create the string type point attribute with name shop_vm_surface that point to shader. It doesn't work. But if I write a shader name in the Shading tab of object that works fine. So the first question is how to create a pointer to the shader properly (if it's possible). Other question is how to create a properly reference to shader that defined inside OTL.

Not quite sure if this is your problem but it can happen that you are trying to render with a shader that Houdini has no idea that it should be sending the shader definition to Mantra. So if you look under the Specific tab of the MantraROP you should see a parameter called SHOP References. Set this to Declare all SHOPs and Houdini will inform Mantra about all shader definitions in your hipfile regardless of whether you're using them or not.

That was a "Use indirect references" flag Solved.
