Maxscript find specific vray material in the scene

Question

I cant seem to get array of some types of vray materials. For example i can get default VRay Mtl with

mat = for m in scenematerials m.category == #VRay collect m

but if i try to collect #VRay2Sided or #VrayBlend it returns an error. Do they have different flags and if yes, where can i find full documentation of vray material flags?

Answer 1

I got it. VRay2Sided and VRayBlend are standard category so to get them you need to write

mat = for m in scenematerials m.category == #standard collect m

And if you are not sure which category some material is just type it in listener

materialName.category

and it will print out its category
