When I was in 3DF class at Full Sail University I learned some very important optimization techniques to save a couple of polys on 3D models but the unfortunately I’ve forgotten most them.
In the class I learned how to model in quads. They said every vertices matters when meshing out a model. Don’t add any vertices if you don’t need them.
Say I wrapped two edge loops around a model. How could I merge them on one side while keeping the quad topology consistent?.. This is an advanced technique and sadly I forgot how to do it.
Any help on clearing this up would be awesome!
