I am currently working on a mod that adds a few new custom test-drive backgrounds for the creature editor. Everything's going fine for the most part, but I am encountering one major issue. For whatever reason, I cannot get my transparent textures to appear transparent in the game. Here I have a background which is a 'night time' version of the default background. Note that the trees and shrubbery are surrounded by black boxes.
I have tried both the alpha and exclusion settings in the blender rw4 material setup, as well as tinkering with some custom properties, but to no avail. I am definitely certain that the DDS texture itself has transparency, as it displays properly within Blender. If someone could please help me figure out what is going wrong, I would appreciate it very much.
