Editing and creating car textures

Can anyone tell me how to create or even edit an existing car texture with either Adobe Photoshop, 3ds Max or any other compatible program. I have bothe 3ds and adobe but have no idea where to begin. I especially want to edit or create a car texture for spinning coasters such as Spinball Whizzer at Alton Towers and others I make myself using that coaster type.

I do not think that 3Ds Max can help you create a cartexture, as it is for making 3Ds, not pictures.

All a cartexture is, is a picture, that has the parts of the train car placed in the proper locations.

I am bad at making cartextures still, so I can not offer much help.

search on the internet for nolimits cartexture templates, and there are ttorials all around, just load up photoshop and load the template and the rest you will learn yourself

I'm pretty sure that I have posted a tutorial on this in the articles section. take a look in there.
