Materials are not visible in the materials sidebar in Rhino 8 Beta

Simple question. Where do I find the list of materials that I uploaded for my drawing in R8 Beta. I only see the last one I uploaded and no others.

Hi Joe -

I’m not sure what “uploaded” means in this context.
When you run the Materials command, a panel should appear that has all materials that you have in that model.

Uploaded means the materials I chose from a folder to use in my drawing. I find this process of using materials much less efficient than in R7. I clicked on materials in « panels », which then opened in Render but the materials window did not open, I had to click on materials a second time to have access to the window where I could select my materials.
