I'm getting very large build sizes. Upon inspection in the editor log I found these stats: Code (CSharp): Textures 365.2 mb 4.3% Meshes 6.2 gb 75.1% Animations 565.3 kb 0.0% Sounds 149.9 mb 1.8% Shaders 7.0 mb 0.1% Other Assets 16.0 mb 0.2% Levels 1.5 gb 18.2% Scripts 11.6 mb 0.1% Included DLLs 13.5 mb 0.2% File headers 961.4 kb 0.0% Total User Assets 8.3 gb 100.0% Complete build size 8.3 gb Following that were probably several hundred if not thousands of "Built-in Mesh: Combined Mesh (root: scene)". I believe this comes from static batching. Some of my scenes have many thousands of trees. I tried a build with static batching enabled on the trees. Mesh size was 7.4Gb. Disabling static batching on those trees reduced the mesh size to 6.2Gb. Now for obvious reasons I don't want to disable static batching on everything. Is there any way I can reduce the size of these combined meshes?
