The issue does not happen when I first open the file. After working with the materials for a bit it starts to happen. I then have to quit the program and open it again, at which time things work normally again for a while. I cannot reproduce this at will, but it happens regularly. Not only with this file. I have the same thing happening in other files too. I will make another video when it happens again.
Another thing that happens is that when the object I want to make adjustments to is selected in one of the Rhino viewports (perspective is what I use most), the viewport inside the Material Editor is empty, and I can not get the object to display. The only way to get it back is by quitting and restarting the program. I also cannot make this happen at will, but it happens regularly.
I don’t remember about the lights. I may have worked on that file since I made that video. However that issue with the many materials keeps happening also. As you can see in the video the stainless steel material is nine times in the Model Materials. That is also one of the issues, I did not duplicate that material consciously. The program seemed to do that. I think other people have posted about this issue also.
There are now still two stainless steel materials in the model materials section. I would like to delete one of them, but I can’t figure out how to do that. Is that even possible? I would think that it should be possible.
That is not what I expected. I thought I had matched the material to both sections, so that when I make changes for one, it is applied to both.
