We have one character artist at the moment who is mostly inactive.
Another skilled character artist is definitely the position we are in most need of right now. So don't hesitate to apply if you think you have the experience/skills and are interested in being part of the project
Currently PBR is not technically supported (at least not fully) in the Source engine and requires a lot of graphical programming to implement anything resembling it from what I'm aware of. So we currently are not using it. Although we would love to.
Of course, do you have any email for share my portfolio?
