Mirage Source 4

[Clu]

i just downloaded this and uhh, when i try to map, if i go up to the higher layers, well the layers work, but the invisible color doesnt, like it just copies black onto the overtiling, so basically you cant map 0.0, or is the invisible color not black and some other colour?

[edit: im a giant tool, and just realised it was the tile set... sorry blech, yay for retarded mistakes., thank for the help though.]
