The new scenario assembling philosophy of this old project: MDL scenarios only. Since even with .dds textures some textures can't go past 4096x4096 in resolution, i found out that you can actually break the meshes in several pieces and export each one individually. They look almost seamless in gamestudio, and can have both backed shadow and complex bump details from a heavy render. Those shots still have the old player character, but he'll be replaced by a newer model very soon.
