Hi Wildbat,
Really great detail on the 190! How do you go about making those larger screw holes? They look very effective as well.
Yes, that's a good tip. I play around with the blend modes a lot, particularly for highlights and shading FX (in EAW we have to do all these ourselves - no fancy game engine to do all the lighting FX for you!).
On panel line and rivet layers I actually prefer to draw them as Raster layers and then convert them to Brightness/Contrast Adjustment layers. This gives a lot better results particularly when you have backgrounds with highly varied brightness - like D-day invasion stripes for example.
Everyone has different techniques, and it's great to have a board like this where we can share and learn from them.
Chompy.
