There are very few people to trust in this industry when it comes to online training (or any form training for that matter!)
Viscorbel is one of the few exceptions and has proven this once again with a out of nowhere “Holy Grail of Tutorials” focusing on micro swirl scratches seen in almost every material to some degree but especially noticeable in car paints. It’s always been a near impossible task to simulate this effect so head over to his page and take a look for yourself.
Hopefully he releases a more in depth video break down of the process in the future.
