8 Textures for a Terrain?

Scene & World Building Terrain

Are there any tools out there that make applying 8 textures to a terrain procedurally easy? Is it even possible? If I understand terrains well enough, the standard is 4 textures because the splatmap only has 4 channels’ worth of information, right? I think I remember reading somewhere on these forums that any more then 4 textures means the terrain would have to be drawn more than once. I’m assuming that’s because a second splatmap is used for the extra textures, correct? And if that is true, then I could use 8 blended textures on a terrain at the expense of the terrain being drawn twice?

Am I on the right track here because I’m willing to have my terain drawn more if it means I can get 8 textures in there somehow? Anyone know how I could do this?

Your assumption is correct, to have more than 4 textures, you need additional splatmaps.
But Unity supports multiple ones of them as you assume, so feel free to add more textures and unity will take care of it :slight_smile:

Ok. So, what is the best approach to importing two splatmaps to be used? I am using Tom’s terrain tools to import one splatmap. If I wanted to import a second to be used, would I have to modify the scripting somewhere, or is there a simple function such as Terrain.SetSecondSplatMap() (I know, but it would be handy).
