Reply To: Shading issue with boolean operation when joining tank main gun and shield

@kroneborge I do not understand your model and don’t know how and why you used a Boolean.

You have too many Vertices where the cylinder connects to the cube and too many edges on the cylinder (result from Solidify?).

Anyway, the boolean is too far away from the edge to cause any shading artefacts. (Or did you perhaps boolean the shield to the cube???)

This is what I would have done:

I tried your way, as far as I could see, but I couldn’t reproduce any shading issues on that edge.

Could you post a link to your .blend file (upload it to Dropbox or Google Drive or other cloud service)?
