However, since A7 now also renders meshes, there's no problem with concave blocks - so why no extrude feature after all?
Because WED does not build with meshes. It builds with CSG. They are completely different animals. What really needs to happen is WED and MED need to be ditched and a completely new editor that is completely based on meshes (polygons) needs to be created.
well i have still problems with concave blocks!
I get an error with NEWEST WED Version about :
MAP DOESNT ALLOW Concave blocks!
That is because you build in WED using BSP correct CSG objects! Study and learn (like I have already said) if you want to understand how this all works. If you want concave blocks, then build your level geometry in a 3D program and import it into WED. WED only allows you to build, in the editor itself, using BSP correct CGS objects.
