Well i saw a tut on this site on how you can change the color of a car, I have been looking around without any luck. Was hoping someone could point me into the right direction, i just want to change the colors on some concept cars. IE, 08 Syline GTR.
render the body and copy it on a new layer, then ctrl-shift-u after that just go to image-adjustments-viarations and at the top slide the bar to coarse and then pick ur colors
Bah....this kind of techniques are call photochopping basically use the pen or pologonal lasso tool to select the entire car, then deselect the lights windscreen etc that u dont want changed then go to Image > Adjustments > Hue & Saturation and play with the settings... Hope this helps if not there are whole communities of photochoppers out there that can help u I did an example 4 u
there are plenty of different ways to actually change the color but the best way to select the parts you want changed is with the Pen Tool
