original picture size 1500x1000 px
I tried to exported some sh3d models to Kerkythea free renderer.. Settings there are huge. But it was too much for my graphic cards
... So thanks to sh3d for this free rendering. I read in some review that sh3d have not good rendering. I can only say it's not true. It's cool for amateurs. You can make very nice pictures here too. Maybe not pure photorealistic /but I am sure it is possible but not by my skills and comp/... It's very simple and very well-arranged....
