Good evening! I just have started to work with Unity/beginner. I created a Test-Terrain for testing my own Textures - now I`m wondering, why I only can load/apply 32 textures into the Terrain Textur Field. When I place more then 32 textures and I try to paint - it all turns out black. Thanks for your help! I have Unity 5 / free Version.
To be honest, I’m surprised you can get 32: I thought SM3 had a limit of 16 texture samplers, although I guess the terrain shader is splitting the render into multiple passes and then blending them.
If you want more than that, you’ll need to write a custom shader that batches the textures into more passes.
