I keep trying to create a glass texture by following every youtube tutorial I can find. They all say just turn the transmission up to 1 and turn the roughness all the way down on a principle bsdf node. But every time I do exactly that my surface just turns solid black. I think it's because I have version 2.93.1 and everyone on youtube uses 2.8.
I noticed that when I DON'T turn roughness all the way down, the texture appears to be like glass. However, I don't mean to be picky, but I'm not happy with it. I want more of a plexiglass look. I'm hoping someone can give me some tips on the look I'm going for and also explain why my objects look black.
