What is Yafray? I’m looking at blender pictures, and get this word… YAFRAY. Well, What is it… What does it do… and Where can I get it, cause it looks cool…

Blender’s internal renderer is a scanline renderer. The main advantage of a scanline renderer is speed - blender’s rendering is done exceptionally quickly.

However, it lacks in a few areas - it cannot do refraction or accurate reflections.

This is where raytracing comes in - it’s a different style of rendering that is more accurate, at the cost of speed.

Yafray is one of the many raytracers availiable (it’s short for “Yet Another Free RAYtracer”) and it seems to be, along with POVRay, to be one of the more widely used raytracers amongst blenderers.
