I'm currently working on a repaint project that requires me to have the back sides multi-colored, with the split being in line with the windows on the sides. However, due to the back sides being curved, I can't seem to figure out how to actually make a straight line right there. Simply making a straight line directly on the texture is obviously not going to work, but doing so does show that the curve is not even the same on both sides.. which is a bit annoying.
I just can't seem to hit the right angle for it. Whatever I try, it just seems to be jagged (the image below is an example to illustrate my issue, obviously it's going to be more smooth).
Are there any veterans out there that can share some tips with a newbie in this field, on how to deal with this?
