Trying to steal Vray's thunder.
Have a look at a new tutorial, which shows how you can quickly create 3d content from 2d images.
Polybrush is a 3d tool, which is being developed by Arseniy Korablev. It’s a very interesting and flexible software, which basically allows you to paint in 3d. Sort of like ZBrush, but a little different. To make these differences more evident, Arseniy constantly uploads new tutorials, which help to better understand the advantages of this service.
For example, this little tutorial shows how do you work with references in Polybrush. Looks really interesting.
You can download the tutorial here or watch them online.
