I've solved my problem. The reason was i have two separate folders with LFS: LFS and LFS.zip, don't ask me why. When I put in the second one my skin, it finally works. Sorry for my stupidity, thank for trying to help.
Yeah, step by step. I have no idea whet went wrong. In the skins folder i Have a for example UF1_DEFAULT.jpg skin, and UF1_GDYNIA.jpg skin, but in the game menu I can see only skins provided with game. Are the capitlics important in files naming?
I read the tutorial, where creating my own skin seems to be very easy. Well, I tried to prepare it step by step, but no new skin appeared in the game menu. What did I wrong? Just had painted over a XXX_default.jpg, renamed it and saved into /skins folder... It doens't work
So what are they for ? It is frustrating to join such server, simply waste of my time . How to recognize in list of servers wchich of them are not dedicated for racing?
Sometimes when I connect to a server and chosse a car and the I try to leave garage, the message is displayed in left upper corner: "agentmarek tried to steal LX6"?
