I'm trying to change the preview of a material from the normal sphere object in python. I found some documentation on it in the C++ documentation under MaterialPreviewType but i'm not sure I have the knowledge to implement that yet. Can anyone help or point me in the right direction? Thanks!

MaterialPreviews are a CustomGui / CustomDataType which is not wrapped for Python. Basically

you would read/write it with mymaterial[c4d.MATERIAL_PREVIEW], but as i said it is not wrapped.

Thanks Little Devil, that seems a bit beyond me at this point. I'll take another look when I understand more about Python.

Is the material preview type still inaccessible from Python?

I'm afraid the Python API still doesn't support the MaterialPreviewData type.

And is there any way to access the general c4d settings to change the default material preview ?

Nevermind, got it :)

one can change the global settings by accessing the world container. Please notice that "custom" material preview scenes have to be set differently than default material preview scenes.

worldContainer = c4d.GetWorldContainerInstance()  
# set a default value  
worldContainer.SetInt32(c4d.WPREF_MATPREVIEW_DEFAULTOBJECT_MAT, c4d.MatPreview2Torus)  
# or set a custom scene  
worldContainer.SetInt32(c4d.WPREF_MATPREVIEW_DEFAULTOBJECT_MAT, c4d.MatPreviewUser)  
worldContainer.SetString(c4d.WPREF_MATPREVIEW_DEFAULTUSERSCENE_MAT, "Cylinder (GI)")
