I'm working on a Lego project where I build models out of Lego bricks in LDD and then import them into Blender via various hoops - inside Blender I then optimize them before loading them into Unity for a small game.
The problem is that Lego has so much geometry inside a big model, because it consists of many small bricks that all have studs and at least 6 sides.
I'm thinking that there must be some kind of tool that can raycast all around outside the model and then delete/group/select all internal faces. Do any of you know of such a tool or where to find more information on this subject? Even just a more correct term would be helpful for my google ventures :)
Thank you! <3
