Blender 3D: Designing Objects

Compositing the render layers

We have seen that the rendering in the Cycles Render engine is quite slow but of very good quality, while the scanline Blender Render engine is faster but with a lower quality.

Thanks to the Blender integrated Compositor and to the render layers, it is possible to mix separated and different passes of both the renderers, obtaining a compromise between quality and speed, for example, by over-imposing the glossy pass obtained in Cycles on the diffuse pass obtained in BI, and so on.

Getting ready

To mix different passes obtained from the two render engines, we must first apply some modification to the materials of the library file:

1. Start Blender and load the Gidiosaurus_shaders_Blender_Internal.blend file, which is the file ...
