Hello, I'm looking for someone to help me. I would like to mod the game so that I can have "Very High" ground textures only without the bump/parallax maps on them. The way they morph as you crawl and move over them is distracting and kind of taking me out the game. I would like for only the ground bump maps to be removed and not any others. Does anyone know how I could accomplish this? Thank you.
