Im having trouble to get the textures with transparency to work.
I have created a texture, in PNG format. I'm using a PK3 file instead a WAD, so there is no software changing the PNG image.
All seems correct, and The Gimp shows the transparency correc, but when in game:
-> If i set the image background transparent, the texture is not shown
-> If the image background is black, the texture is shown, but the black scale is not interpretated as transparency scale, so the game shows the black scale as a normal color.
Im trying this with 1.30, and i think i'm missing something, because other maps with similar textures are shown correctly...
Even when i use those map's transparent textures on my map, i got the same problem as when using my texture, so i think the problem should be in the map.
I tested the map on GzDoom, and work fine.
What could be the problem, then?
