Hello All I work with RTB. Happy with it and not. But at this moment learning still blender. Maybee in the future combi work with blender and rtb. My problem is, if i us my 3d grass objects or trees, they came when i am driving in assetto a little bit to late (laggy). I think the problem is the kb or MB of the textures. What's an optimal KB size of a texture to come asap on the map in ac? I hope you understand my english. I am working on Gubbio Hillblimb.. Track is ok. I can make models in blender. But at this moment they aren't perfect in the game... Any help realy appreciated.. Best, Fab PS: Also a problem is, how to desing the map with more than 4 textures.. That's a RTB issue at this moment..
