I would never update a mod without renaming it (creating a second version etc.) because naturally builders would be pissed off. I honestly don't know what the problem is you are experiencing. But I can only suggest the thing others have already pointed out: restarting the game. When the game doesn't show Alpha Channels (transparency) it doesn't necessarily have to be black, it can also be a pattern I think. So that's mabye what is confusing you...
That's a serious question? Anyway...if you wanna know: It's Eminem - Till I collapse I think. Those are some very beautiful textures rafale, thx for sharing ^^ Btw. Igntul has a new track with a new mod of mine that he modified...a horror themed mod. Check it out: Track Info - TMX
I just saw in the french TM forum that rafale made a new mod (medieval themed), looking pretty neat on the pics...can't test it ingame right now though. Thought here was the best place to post this as rafale had posted here earlier already... Trackmania :: Voir le sujet - [Mod] medievale
