I have some new problems,need some help if this happens to someone,i created some grass xpacks,and i create short track to test that xpacks and its work fine on that track.But when i try to use that grass on my main project after loading screen RBR chrashes on desktop. I was have same problem with some large objects,with some houses and i was think RBR crashes because that object was complicated,because is not simple object like grass or tree,it was same thing,on test track,that object work ok in RBR but in my main track same thing it crashes?? Everything in that xpacks is regular,power of two,dds with alpha channel,etc,but in main project RBR crashes and in other dont crashes,have someone same problems ???
