Please help me decide - to stitch or not to stitch. (We are planning to use this model in Unreal 3 game engine.)
You can see the situation in the pictures. There is a wall and an arch. In the first case the arch is stitched into a wall, which leads to the formation of additional triangles. In the second case, the arch and the wall are two different meshes combined into a single object, thus reducing the number of triangles.
There are conflicting opinions at the moment on what is best in this case. Any suggestions?
