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....
