Texturing very large mountain-like Mesh

I’m trying to create a very large wall for this game I’m working on. It is absolutely massive, and it needs to be 1 uniform mesh. How would I go about texturing this? I know I need to use a tiled texture, but it needs multiple materials, and it is unclear to me how I’m supposed to paint for instance grass onto rock or ice on something that ISN’T a terrain. This is its own static mesh that is separate from the terrain. How would I go about painting multiple materials onto this large static mesh?

Thank you!

5-Way Material Blending Should get you started.

You might also want to work in mix maps to make the transitions between materials more natural. Some examples.

I hope that gets you pointed in the right direction

Hi Majkl,

Try Vertex Painting and it’s called Mesh Painting , you will need a lot of vertex here is the link in the Docs

Hope i helped you .
