Hello everyone, can I ask you if you want have improved compilers of Uncle Mike ( UMHLT ) and it should up to -/+32768 and it can fix for hidden texture holes. Why not? Link
So sadly because it works only -/+16384. If you want get source from Github but ( only Xash version ) If you want check and merge different code from UMHLT of Xash version and SC Compilers.

Than modified ( UMHLT ) SC Compilers build clean bsp for SC 5.0.x without hidden texture holes.

I hope you have to get success without stupid texture holes.
