SetCineFilterTexture with custom texture?

[MasterWarlord]

Hey, I have a functioning trigger that blanks a player's screen out for a few seconds. It works fine with the base game cinematic filter textures you're supposed to. I wanted to flash a custom texture over the screen, but the game wasn't having that. It just shows a brown filter out of the screen for my texture, instead of plastering the image over the screen like I want. My texture is being registered, because the brown color is unique from the usual cinematic filter masks. Any suggestions?
