At the Set Heightmap resolution dialog we have access to 7 options. AFAIK, the 3 first are the dimensions for the mesh, and the 4th, Heightmap resolution, is for controlling the resolution of the terrain mesh. But what do the other 3 exactly do?
Is the Detail resolution used for a detail map? If so, where can we add in the editor a detail map for our terrain?
And what about the Control Texture Resolution and the Base Texture Resolution?
Thank you in advance,
It’s nothing you add manually, but rather it’s built when you paint detail objects on the terrain.
Control texture is the splatmap used for the textures…the higher the resolution, the smaller the “pixels” are when painting textures on the terrain.
Base texture is basically the same thing, but applies to the flat color substitute for the textures that’s applied when textures are far enough away.

Thank you very much. So, is there any way to use in Unity a detail texture for the terrain, so that it is shown multiplied over the terrain textures, but only near the camera ? I mean like the detail textures used in other engines?
In a way it already sort of works like that, where you have plain colors in the distance and normal textures closer up. But no, there isn’t a way to have a detail texture on top of that. You can use detail textures in Unity, but not with the terrain engine.

Thanks for this explanation. I had not paid attention previously to the difference between the settings for Control and Base textures.
A trick I learned from this: you can increase the resolution of the base texture to improve details on machines with low end GPUs. Improving this resolution has greatly improved the appearance of the terrain on my end even for this lowly GeForce2 MX.
Unfortunately I was reckless and experimented with this on a work in progress and lost all my texturing. Arg! How stupid!
