Playing with a new LDD rendering tool: BlueRender.
The images here are a part of a larger image. The one on the left by POV-Ray and the one on the right by BlueRender.
The full image took 30 minutes to render using POV-Ray, but only 4 minutes with BlueRender.
More info about BlueRender. Please note that this is a 0.0.1 version.
