Custom Fade Filters

So i imported my own blp file but when i try the filters it just fades black, i even tried the preset Panda-n-cub filter but that shoes black too, whats the right trigger to get the filter to show??

you have to change the coloring of the filter to 100% red 100% blue and 100% green in the trigger editor.

make sure your picture was not saved 1st as a gif. Make sure it is always tga. And dont have to be blp.
