I know there is a lot of problem with atf and alpha... my problem go , i think, with the fact that there is no alpha blending in ATF format ( i think)
I'm in a isometric engine and when there is 2 tile that are suppose to merge correctly, there is a black line between them.
I searched but i didn't find , or didnt understand, any solution.
If there a solution to make better alpha with atf and fix those kind of problem ?
P.S : everything work perfectly without ATF (just png)
