I'm a beginner in Blender and am doing the BlenderGuru donut tutorial(doing the cup portion of the old one and geometry nodes sprinkles of the new one), but wanted to do something more by adding a Homer Simpson pic on the larger plate(surrounded by donuts on the edge, but irrelevant to this). Problem is I can't find why…
The Material Preview usually casts no shadows so you can't see this and because you set the alpha of the image to control the complete alpha of your material your plate would be transparent outside of homers head. So i assume you have some geometry copied and must have accidently elevated this a bit. You don't need this if…
