Fx textures not showing up in game

so I added a number of fx’s to our PW haks ,
they were added to our 2Da files
they show up fine in the the toolset but when I go to look at them in the game they are missing textures . Verified that the proper DDS files were in the hak for the fx .
Any ideas why this is happening?

Could it be that the F/X is using TGA files of the same name? I’d open the F/X files in the editor and check.
