How to camouflage a mech/ make see through decals:
Create the camouflage you want to use and add it as you would an insignia so that the entire camouflage is covering your mech.
Next take the camouflage layers and merge it with the other visible camouflage layers (only if more than 1 layer was added).
With the camouflage layer selected change its mode to Multiply.
Now hide all layers except for Paint and the camouflage layer. Right click the camouflage layer and select Merge Down.
Make all the layers visible and remember to set Paint Layer Mode back to Multiply.
