Hi,

I sent a video. That's better than sample scene.

Thanks

TomG:
Well, the example scene is generally better than a video, because then we can try to reproduce here and test fixes here to see if it has resolved it (if we can in fact see the same problem here), just as an fyi. With a video, if we don't have a scene that we can reproduce the issue, then any fixes have to be rolled out, you have to install, you have to test, and only then do we know whether the fix correct the issue ;)

OK, I sent the example scene.

Hi everyone! Sorry to revive this thread, but it seems that this issue still stands.

I am having trouble with the material preview as well. Standard C4D materials generally preview super accurately, but Corona materials go black or grey and make the scene difficult to navigate in many cases. Basically, anything more complicated than a diffuse material will render the incorrect color/shading. It would be helpful to not have to open another window (IPR, etc.) to see these materials while I am simply modifying the model. I like Corona because it makes rendering simple, but these material previews make the workflow more complicated when I am trying to achieve a particular effect. Rendering on the CPU always takes more time than the viewport preview, and many times I am simply trying to accurately place a material on a surface. If I have to render every time I want to adjust a material in a large scene, it is actually faster to use a C4D material first, make adjustments in the viewport, and then convert to Corona material. But this is not ideal, especially if I have to make a change after converting to Corona material. Then, I will have to create a C4D material again, find the appropriate texture, replace the Corona material, adjust the C4D material to my liking (or the client's liking!) and then replace again with the Corona material. This is many steps that should not be necessary in the workflow. It would be very helpful and save me a lot of time if Corona materials would preview more accurately.

Best,
Clayton
