@ all : thanks !
@ Roi Danton : the weathering on this one is light. I use some (not all) of the layers from the flanker's template, and add my own, three layers per colour (one for the general aspect, and one for the structures). I intended to make a look "used" but not dirt. I'm happy with the result here, but I can progress a lot...
The alignement in some parts is really good because I've made a pattern. For the rest, I think it is good. Actually, I work on a Mac, so I must reboot each time I want to test my modifications...
@ Cosmonaut : thanks for the pictures. I knew the first one, that I used to choose the colours. It's the first time I see the second, and it's obvious that the scheme is grey, not blue... But looks better in blue (?).
But most of all, I wanted to thank you a lot for your "cdds tutorial", which is really well done and very useful. Great work !
