Custom Cartextures?

This is for users who are amazing with cartextures...or anybody who knows how to use it.

How do you make custom cartextures for nolimits?
because I want to have my trains look more with the ride instead of using the default textures.[:D][:)][:p]

paint.

any image editor will work. And instead of "Save" Do "Save As..." and name it something unique.

Photoshop or any layer based program able to deal with alpha textures would be the best

Load in the default texture (found in the cartextures folder), select parts u wish to *paint* over... etc
