I'm totally new to Blender 2.8 and trying to learn from Youtube videos. It is going well, but I have this problem.
I have some LEDs (imported as STL files) and they look okay when the render is set to Eevee, but they totally disappears when set to Cycles.
In the material I can change between off and "on". If I turn it "on", then it is actually shown in Cycles, but I cannot get the off version to work.
I hope this is a simple beginner mistake somewhere, but I cannot find it!
Kind regards, Claus
