Thanks for your answer.
Actually setting the smooth flag doesnt solve the problem, just increase the compiler time.
And about the hiRes just in the pro version, i just cant believe this can be true. I hope there is another way to workaround this problem.
I dont understand why hiRes its only available in pro version, but its harder to understand either why the commercial version should have this stupid ligthmap resolution.
Someone knows how to solve this question please?
