Hello! Hmm.... I know that it's somehow possible. I figured part of it out, but I'm still not successful. Here's what I've done so far:
1. Created the plant image with the background removed.
2. In Med, selected the texture file in the Skin Settings menu.
3. In the Skin Settings menu, under "Texture Format", I selected 32bit + Alpha.
Since my .tga file has a built in alpha map, I really expected it to work without any other steps -- but it didn't. Maybe there's still a problem with the paintshop pro style alpha maps? I continued by doing:
4. Created a separate image with the alpha map in blacks and grays.
5. After checking the "Alpha" checkbox in the Texture Format section under "Skin Settings", I was able to select the "Alpha Texture File". I thought that might work, but it didn't seem to do anything.
Any ideas?
Thanks!
