I can't paint all that hot, although I aspire to one day. This was an article that was published in No Quarter Magazine about 3 years ago and I thought it was pretty interesting as it's a very good 3-d effect without cutting into a model or using salt chipping. Some of the better painters here I'm sure are familiar with this already and can do this, but thought I'd post it for the paint impaire people like me
A lot of these techniques used to be found on www.brushthralls.com which is basiclly privateers in house modelling/painting crew. But looks like they removed a lot of the old articles.
