I found this a few minutes ago, and i found that this is a very useful video for modeller like me or anyone wanted to know more about Weathering with Pigments.
I for one never used pigments before in my build, just because i dont know how to properly apply it but after watching this video, i'm definitely going to try it on my next armor build....
In fact, watch all of his video, all feature a very nice and easy to follow tutorials regarding modelling especially on how to apply all those techniques that you read so much about on the internet.
He also have a blog at http://armorfarm.blogspot.com.
thought i share it.. :)
