Thanks Maxime! I'm relieved it's a bug, I was looking everywhere for functions to manually fix the OpenGL preview. I will try with this approach.

Hi Maxime,

The PSD file is just a test file, so at the moment it's a very simple layered file. Four layers, everything completely rasterised, no text or effects or anything special. Here's the code I'm using - you'll need to replace "/MyPath/test.psd" with a path to your PSD image.

Than you so much for helping!

    # Create a new material from scratch
    mat = c4d.Material()
    mat.SetName(matName)
    doc = c4d.documents.GetActiveDocument()
    doc.InsertMaterial(mat)

    # create a texture shader and assign it to the color channel
    
    # enable the color channel
    mat[c4d.MATERIAL_USE_COLOR] = True
    # create a bitmap shader
    texshader = c4d.BaseShader(c4d.Xbitmap)
    texshader[c4d.BITMAPSHADER_FILENAME] = fileName
    # provide the layer set information
    layerSet = c4d.LayerSet()
    layerSet.SetMode(c4d.LAYERSETMODE_LAYERS)

Hi,

Newbie here so forgive any breach of protocol etc!

I'm trying to use python to assign PSD layers to individual materials, then apply these materials to a texture tag on individual planes (this can be used to create a pop-up book effect for example). The material previews look fine in the material window, and perfect when rendered with the standard renderer, but in the C4d view panel they all appear as the PSD layers all merged together (see pic attached of viewport vs rendered, with the material previews below). I suspect I'm missing a command to create a specific viewport or OpenGL texture from the material, or from the shader... Does anyone have any obvious suggestions or pointers?

Thanks, Yan.
