RTF is a global modification that replaces all towns in the game.

Ha, the last time someone asked such a question in the Modding section, I started preparing screenshots and wanted to share what I knew, but I got lazy))) Now the screenshots came in handy.

One line in the material is responsible for transparency; usually, we write AM_ALPHA_TEST there, but there are also other settings.

AM_TRANSPARENT is a setting from the Ghost; as you can see in the corresponding screenshot, there is a problem: a transparent texture is overlaid on another transparent texture (like a face on a hood), resulting in an unsightly spot. I once made a Ghost and, frankly, I got tired of erasing all the textures of the underfolds or the reverse sides of clothing on the sleeves, hem, and shoulder cape.

AM_OVERLAY_ZWRITE is from the Genie Vizier; it's a strange thing. You can see that there are holes in the hem where the polygons overlap... the Genie has the same bug; he has piercings on his nipples, and from some angles, you can see that the square creates a hole.

AM_OVERLAY is a strange thing; it's as if the unit has been turned inside out.
