There appears to be a hard limit of 4GB of textures in the standalone build. If your project has more than 4GB of textures, then some of the textures in standalone build will be messed up. While this limitation may be acceptable for mobile projects, this limit is completely unacceptable for PC projects. There are currently two threads in the forum about this bug: https://forum.unity3d.com/threads/textures-messed-up-in-windows-build.440675/ https://forum.unity3d.com/threads/texture-problem-graphical-corruptions-need-help.395985/ Can somebody from Unity please comment on this bug? Thanks.
