Hi
I'm new to Maxscript and I would like to create a script to select all the object in the scene which have a raytrace map in their material (diffuse or reflection slot)

I already tried a few things but failed. I think it can be done with one single for loop.

select (for o in objects where o.material ... = raytrace () collect o)
=> I wonder how to reach the material maps after o.material


Can anyone help me?

Create a box, assign a standard material to the box and type:
show $.material

You'll find out all of the properties a material has, this one looks interesting!
.reflectionMap

If you put a raytrace material in the slot and type
classof $.material.reflectionMap

It spits out

Raytrace

evaluate:
(classof $.material.reflectionMap) == Raytrace
true

True! Perfect! You'll also want to check the classof $.material for RaytraceMaterial to get the actual RT Mat.

^ Use these to help you figure out these problems in the future :)

If you're using VRay Materials, then calling .diffuseMap will throw an exception, use the method described above to find it's properties! Also check for isProperty $.material #reflectionMap to see if it exists so it doesn't throw an error.

Best of luck Scripting,
