Hi Yuriy! It should follow the same idea. We introduced this in Roassal because we needed it. It will be the same in Roassal3d. I have just committed this. Another question, have you experienced some problem with the rendering? Milton sees a black window, whereas there is no problem on my desktop and laptop. Milton has a Windows PC. Have you seen Woden/Roassal3d running on a windows?
