So I modeled a mountain in Blender, and I import it yo Unity. The problem is I can’t make it act like a terrain. Is there a way I can texture paint that mesh? I can collide with it just fine, but I can’t paint it. I tried to assign a Terrain Component but it doesn’t paint on it. Any help?
Your best bet is to paint it in Blender, then use the texture from that.
You need to map texture coordinates in Blender. Go into edit mode, select all vertices, and press u to unwrap.
