Hi OpenMods devs,
I've seen that your tank/fluid alpha textures are not working as intended (https://i.imgur.com/HFSbYme.jpg).
GregoriusT, the dev of GregTech, also had this alpha texture problem, but he was able to fix it.
I though this would be of interest for you guys: http://forum.industrial-craft.net/index.php?page=Thread&postID=182222#post182222
If not, just close and ignore.

Yup. This snippet was for blocks (which automatically solve transparency issues out of box). Tank liquids are rendered as tile entities, so face sorting is unavailable.

The solution was no solution, pls ignore this.
