Mclelun has posted a series of 'paint overs' that all use a Blender render as their starting point. Using a slider you can explore the 'before and after'. Pretty cool!
Sometime I used 3D render as a base for my landscape painting, especially those involving man made structure. In this entry, I will share with you some images of before and after paint over. So you can get to know, how much painting I had done on them.
Lots of comparison images below. Might take sometime to load on slow connections or PC. Refresh page if images are not load. Drag the slider to see the differences.
