Terrain engine - texture stretching

Unity Engine
1

When I’m using the terrain engine and I begin to create cliff walls I’m noticing that the texture I’m importing stretches. It seems that the displacement with the sculpting tools enlarges the polygons, thus causing my textures to stretch along the walls. When I use the default texture that comes with Unity, the green/gray rock texture, it looks decent.

What solutions can I do to decrease the stretching look? Is there a way to subdivide the entire terrain mesh to add more polygons to the walls? Maybe I’m doing something incorrectly…

Any advice would be appreciated. Thanks!

That’s a drawback of heightmaps, since the polygons are on a square grid which cannot be changed. There’s not much you can do about it as a general thing, but for specific areas, you can make an extra squished texture in the direction of the cliff, so when it’s stretched out, it looks more normal.

You might also try changing the tiling scale on the splat import to not be square – that should have the same effect as creating squished texture in PhotoShop or whatever.
