When I run my map on my phone the textures all get dropped to super low res and many of them get covered in little multi-colored dots. Where do I control the texture compression settings for android, and what setting might be the culprit for the rainbow colors?
Click on your texture in your project and in the inspector at that bottom there is a “texture format” setting that controls quality and compression. Note: you get even more options if you select “Advanced” Texture Type under Texture Importer in the same panel as the “texture format”. Click the ? button at the top of the panel for a detailed explanation of each texture format setting. Good luck fighting those rainbows.
I had this same issue and I fixed it by going into the Build Setting and changing texture compression from “default” to “snapdragon”. I have a snapdragon processor so I’m not sure if this will work on other processor types or not, however.
