Is there any interest in a comprehensive tutorial covering these? There is very little information around, especially about wet textures. A lot of what I've learned has come from trial and error but I've gotten it all down. I could explain how to create all three textures properly, how to import them into the game, use them in your map, and how to export them into a u file right.
"You damn kids, back in my time we made the items, maps and games ourselves with an unwieldy engine using counter-intuitive crash-prone tools and we liked it so much we built communities around this which nowadays look like cults because they're quasi-parallel societies based on the same old games." -Hellkeeper
