I´ve read threw the whole forum,
threw wiki,
threw directx9 sdk help,
threw nvidias developer site,
threw atis developer site,
threw the manual of gamestudio,
threw all aums,
I made several downloads with a few hundred mb,
but I found no solution.

So I told my problem here, at the place of the experts.
I don´t want to describe the problem in every part of the forum again.

It is not a question about 200 textures on a terrain,
it´s only a question of one stupid detailmap on a terrain,
like it was possible before (and, I know, is still possible)
with detail_size.

Hello, experts?! Anybody out there?
