Hey Guys,
I also just started skinning,
my try is the Kenworth T-600 at first. (Forget TITAN

)
Here you see a skin, that doesn't seems to be available for your truck,
I replaced the purple/black one with this fancy one for testing.
Here some shots:
I still have some problems with the Alpha Channel,
but I think I can sort them out.
A problem (don't panic, it's the only one yet) is:
By using a replaced skin, you can't use FlipFlop/Chameleon effect on it (what you can buy on Truck Stops).
The game crashes to desktop, if you try.
Reason: By using FlipFlop/Chameleon effect, the original skin appears, I think that causes the error,
the game can't or won't handle... why so ever.
But I hope, its a small problem for you guys
All other functions, like upgrading your truck are still working like a charm.
I'll need some time for a whole costom skin pack,
to early for a fix announcement...
just lay back guys, I'll give a shout for release.
