I don’t feel like using unity terrain,so i’m building my own with blender.should i go for say 16x16 chunk 100 times,or 128x128 with 2 big chunks? I guess the 16x16 offers more options with occlusion culling right?Thanks

Big mesh means lots of vertices and tris, which takes more disk space, hence “big”. Unity only allows meshes of no more than 65536 tris, or you will need to divide them to submeshes(Unity automatically does this, but sometimes the results aren’t good). Go for 16x16 chunks.
