Skin Colour Banding Problem

Hi all, I am currently making a Me262 Skin, which has been going pretty well so far. I’ve got to a point when I want to start weathering.

However, I am finding that i have colour banding. which i can’t figure out how to get rid of in the game. I am not sure its because the game can’t handle it, or something in the file size/ format etc that is the issue.

In addition I have been trying to make my own normal map but that’s a completely different subject entirely.

Then I would have results in-game with this.

I have tried different formats, tga, dds, png, jpeg etc but all the same.

The only other way I can think of possibly resolving it is to start from fresh, but grab some of the stencils I have made.

If anyone could help it would be really appreciated.
