Thanks
Cowl flaps only done one side at the moment.
All about exagerating certain things to ger a simulated 3d effect. For eg the ailerons, trim tabs (done usian gaussian blur of solid line).
Rivets are 3 seperate single dot layers.
1) Black rivets
2) White rivets
3) Copy of white rivets run over with an eraser brush set to 25%. Do multiple passes you get left with the effect of some being lighter than others. (looks like paint worn off them). Set opacity slightly higher than the original white layer.
Can't remember who first thoguht of it, someone here, but it looks great.
Paint chips is the bit I haven't quite got the hang of yet.
