i have some trouble with the terrain, i have three 5000 * 5000 * 650 Terrain, but the texture paint brush is much to large with Brush-Size 1. compared with a real object its like an airplane. but i need much smaler detail resolution for that, that i can paint little Gravel-Ways etc...
I also tried "Set Resoltion, but when i set the heightmapt Resolution (this is the correct setting for my problem, isnt it?) to 4096 it automaticly changes to 4097 and when i click ok it tells me:
Heightmaps above 4096x4096 in resolution are not supported
what can i do to solve my problem?
