Unity Game Optimization - Third Edition

Reducing geometric complexity

This tip concerns the GPU frontend. We have already covered some techniques on mesh optimization in Chapter 4, Optimizing Your Art Assets, which can help to reduce our mesh's vertex attributes. As a quick reminder, it is not uncommon to use a mesh that contains a lot of unnecessary UV and normal vector data, so our meshes should be double-checked for this kind of superfluous fluff. We should also let Unity optimize the structure for us, which minimizes cache misses as vertex data is read within the frontend.

The goal is simply to reduce actual vertex counts. There are three solutions to this:

• First, we can simplify the mesh by either having the art team manually tweak and generate meshes with lower polycounts ...
