Bitmap loader not working on material preview (4096x4096 images)

Corona Corona for Cinema 4D Issues

I can’t see the texture loaded in the material preview, but I see on an object when I apply the material.

Looks like a bug…

Moreover, if I load a bump texture without bitmap loader it doesn’t have effects on render.

I never use the Corona bitmap loader and bumps work fine for me.

The shader preview not working is indeed a known issue.

As for the “bump texture without bitmap loader”, what exactly do you mean? In any case, try it in A6.3 now, as we fixed a lot of issues related to bump-mapping.

Thanks!
