So I can move most of the layers, but what about changing the colours of the layers?
Click on the layer you want to edit. And just paint. I would recommend to edit every "paint area" layer.
The layers which can be paintet (should be painted) are always the latest step of the folders, do you know what i mean? For example:
If every layergroup is "closed, there should be two things:
-Car template 2.0 (with an eye, so its seeable)
-Car non edited (without an eye, invisible and not needed)
You go on the + in front of car template 2.0
There should pop out a longer list, start with: Not recommend to paint. (in it there is the exhaust and the Underbody texture)
Under not recommended to paint, there is: Helmet
Click on the + in front of it.
helmet 1 should pop out. Press again on the + in front of helmet 1
The overlay and some paint-areas should pop out picture. Clicking on Paint Area Visor.
Now you can edit the visor of the helmet.
