@🧯Billy Hughes No one forced me. I tried this solution because I no longer have the flamingo plugin to rhino.
I run windows7 in a virtualBox with rhino on it. When I was a student at a design school over 2 decades ago I had the plugins for rendering. But since then I have mostly used rhino for my own production and thus I never needed the colors and materials.
I have a construction company now and mostly just use rhino for making simple 2D drawings for construction.
