Create VRay material

Passion3D

Hi all,

I know my question doesn't directly pertain to C4D, but maybe someone here will have the answer.

Creating a c4d material is simple, mat = c4d.Material(c4d.Mbase), but how to create a VRay material?

Thanks

Hello,

sorry, but this it NOT how to create a "c4d material".

Cinema 4D has multiple, different materials. All materials are based on BaseMaterial. Thus, any material can be created using the c4d.BaseMaterial constructor and the appropriate ID:

# create Cheen material
material = c4d.BaseMaterial(c4d.Mcheen)
doc.InsertMaterial(material)
c4d.EventAdd()

The Cinema 4D standard material is a special case. It can be created using BaseMaterial . But there is also a dedicated class, that can be used as well: c4d.Material.

# create standard material
material = c4d.BaseMaterial(c4d.Mmaterial)
material.SetName("first material")
doc.InsertMaterial(material)

# create standard material the other way
material2 = c4d.Material()
material2.SetName("second material")
doc.InsertMaterial(material2)

To create a VRay material, you need the ID of that material to use it with c4d.BaseMaterial. I don't have VRay here, but you can easily obtain that ID from a already created material using GetType().

# get the currently selected material
mat = doc.GetActiveMaterial()
if mat is not None:
    # print type ID
    print(mat.GetType())

You find more information in the C++ docs: BaseMaterial Manual

best wishes,

Hi Sebastian,

Thank you for your response. I found the identifiers of the different VRay materials in the file c4d_symbol.h.
Everything works.
