I would like to make tree inside glass sphere but I can’t handle with the light. I don’t want that shadow under the sphere. I’m quite new in 3D world and stil learning Blender so I’ll be greatfull for any advice that can help me.
I’m guessing you have a “floor” underneath the sphere. Lose the “floor” = lose the shadow.
If you are using the “floor” for the background color (dark blue) just move it far away from the sphere (GZ-10 ??) so that any shadows cast end up outside the camera shot.
Post moved to a better topic place.
Thanx for advice. I’ve moved “floor” little lower and made small change of light position. Right now I can focus on finishing inside of shpere.
