I have modified snow tracks to look like dirt tracks, but they dont align and they are not transparent :mad: ! Please check whats wrong:
http://files.filefront.com/th0rn3+texturespk3/;10742124;/fileinfo.html
Its really getting on my nerves. And yes I have added it to shaderlist.txt and it has an alpha mask
Will credit in the readme!
hmm u know, I just used those snow trucks on dirt and they are transparent them selfs a bit, so u don’t need to change anything, they’re looking ok on dirt 
first line in your shader, just write it w/o .tga:
textures/th0rn3/dirt_track
your tga files also don’t need an alpha channel and can be saved in 24 bits format and make the area around tracks black, like in default snow_tracks
and after all that, I took a look on your texture and the tracks were blue instead of orange, that u wanted 
; so better to take the default from snow_sd, or try to play with colors(I think it uses colors of RGB-channels), but here can’t help u so much, not so good in those: blendFunc GL_ZERO GL_ONE_MINUS_SRC_COLOR
oh yea and no need for credit, don’t think I helped u so much
