![]() ![]() Looking at “Combined Mesh (root_scene) 43” Tl dr: We’re going to see a LOT of artifacts. Unity automatically combines meshes that don’t have components attached to them as an optimization tactic.All meshes get triangulated at some point, regardless of what software you use-Unity just does it to them when they are put into a build so that the player doesn’t have to calculate it themselves. The meshes have already been triangulated by Unity.Some important disclaimers about the limitations of extracting assets from builds: When optimizing models for games, people can pull off all sorts of weird tricks to keep the experience smooth. ![]() There are some cons to this, such as the lower resolution & accuracy of the light, but the render time it saves is absolutely worth it. The detail you see is caused by an image called a normal map, which tells the renderer how to make light bounce off of the plane to fake displacement without adding any geometry.
