Hi,
First off I'm new here, and also very new with python.
I'm trying to create a pretty basic material using python, but it seems not so easy.I have two questions:
How can I add the Art shader to a channel?It's not listed in the SDK shader list.
So it's probably not like I'm just missing the right word here, is it ?> matt[c4d.MATERIAL_USE_LUMINANCE] = True

Turns out it's quite tricky to import materials from the content browser too.> fn = "preset://somefolder/Cube.2.c4d"

From my understanding, I have to make a virtual base document and then import it from that.
How does that look like in code ?I only need one to work, but I am very interested in both!

Hi Myosis, first of all, welcome in the plugincafe community!
Even if shader didn't get a proper symbols name, each BaseList2D get an ID. And symbols only refer to this ID.
So if you want to know the current ID of an Art shader. Simply create a shader in a material, then drag and drop the channel where the shader is into the console. Press enter and it will print you the ID.
For the art shader, it's 1012161.About bitmap do the same technique, simply drag and drop the parameter into the console to know the parameter ID.
Then you can create it using the following script
import c4d def main() : mat = doc.GetActiveMaterial() if not mat: return # Create the bitmap shader bmpShader = c4d.BaseShader(c4d.Xbitmap) bmpShader[c4d.BITMAPSHADER_FILENAME] = "YourTexturePath" # Create a art Shader and insert our bmp shader artShader = c4d.BaseShader(1012161) artShader.InsertShader(bmpShader) artShader[c4d.ARTSHADER_TEXTURE] = bmpShader # Then insert our art Shader into the active material, and use it in the color channel mat.InsertShader(artShader) mat[c4d.MATERIAL_COLOR_SHADER] = artShader c4d.EventAdd() if __name__=='__main__': main()
As you already figured out, in python the only way to load stuff from content browser is to use LoadFile/MergeDocument.
If you have any question, please let me know!
