Creating Rich Terrain Shaders in Blender and Godot
This video demonstrates a technique you can use to create large terrains on premade meshes using tiling textures. By scrambling the tiles, you can get rid of the repeating tiling artifacts that show up with simple texture mapping, and by using layers you can build up different biomes on the same mesh. It also includes normal and roughness maps to give your terrain extra realism.
It starts by showing how to create a node network in Blender that you can use to render in Eevee and Cycles. It then demonstrates using a shader library I developed to create the same effect in Godot.
