damn cute textures on your map i suggest going mad plotting objects on them, instancing really works and blender is a great scene composer.
thanks, I usually place my objects and stuff on them inside Unity because I know a lot more about it than Blender and can hide/cull objects not in the camera frustum really easily and use a script to combine objects with the same texture/mesh into 1 draw call.
But if I could figure out a way to do it in Blender and cut down on my materials or combine textures I'd be interested. I was just working through marking seams to split up the meshes UV, but am a beginner.
I'm making these for mobile so trying to learn the most efficient ways. In the past I made tiny tile-able meshes and just repeated them to form hills, valleys, etc but had lots of overdraw and multiple draw calls. Now in Blender I've been trying to keep the terrain around 1k-3k verts/tris with 1x 1024 texture.
