I got some meshes that intersecting each other by a large amount of their surface. To save polygons, I tried to merge them so that the unused faces which are inside those meshes will be deleted and all that remains are just the seen faces from the outside.

This is just a simple example. The original meshes are much more complicated and thats also the reason why the boolean modifier doesn’t work. It just produces crap when I try to use it.
Thanks and best regards.
