I am drawing an optical setup with the laser beam, now I’m using a cylindrical transparent material to simulate the beam, how can I remove the shadow of this object? thanks
Tap on the Environment tab, then the little gear (settings). At the bottom of that window, you can turn off the shadowing. I’m recalling this from memory, so I may have omitted a step, but it’s in this general process.
As of now, only the ground plane shadows can be turned off, the way @McD mentioned, the shadows of bodies cannot.
