Many thanks for trying to put me on the right track. Unfortunately, that was not it. I've also tried replacing the black, white, transparent and widget textures from the same folder. The semi-transparent blocks remain...
I just discovered the game a few weeks ago on Steam! What's more: I haven't even played it yet!!! But as I can see on the web, it's one of the nicest action RPG games out there. And I just LOVE the settings (sunny mediterrean landscapes), but... I don't much like plain old, stuffy mythology. So I needed to add a special flavor for my enjoyment
This is why I am now in the process of making a "ambient mod" for TD:IT, putting everything in an Atlantis setting. It's the same game, but now every name and place refers to something from Atlantis.
I would love to post some screenshots, but I'm unable to make them (with the prntscrn key), and I don't see a button here to add images
I modified the whole UI and intro and menus, etc. to get a good Atlantis feeling going for the player (I'm probably going to be the only one playing this mod, everyone already finished it long ago, so by "player" I mean: me. LOL)
Anyway, the mod is a pure hack 'n slash, so gone are all the typical rpg elements like masteries, potions and such. As is the HUD (the only thing visible that remains, are those semi-transparent greyish backgrounds of the quick bar slots)...
Thank you very much, again, for trying to help me.
