Add a texture to each face of a Custom3DItem Cube in a Scatter3D plot

[AKuederle]

Hey,

I was trying to render a Custom3DObject inside a Scatter3D plot (QtDataVisualization).
This object (a cube) needs a custom texture, with a different color on each face. The object allows to add a texture file, but this texture is repeated on every face and not stretched out over the whole cube. So far i could not find an example to see if it is possible to do that. Therefore, I am not sure, if something is wrong with my Texture, it is just not supported, or I could not find the option.

I would be happy for every advice!
Best Regards
