its not my business but i have an answer: SH 1 has a problem with transparency of some textures, i think bcoz that no one did a texture pack release until now, i see one TP on a russian video but sincerely its a horrible one, posterized as hell. there is someone else REMASTERING it in YT but til today there is nothing available. The Fog effect works like a revealing curtain, if you put the textures without transparency everything popping raw on the screen, there is some textures with this problem, i tried many levels of transparency, alpha channel added with the photoshop method, nothing, its a beetle HW problem, i read something in forums somewhere, its a unsolved thing, i need to do more tests, maybe is not the upscaling itself or transparency, maybe its a COLOR depth wrong handling, i forget to mention the palleted texture hell dumps.
