We just added couple new nodes to library:
- Split Material node. It does reverse work to Make Material. You can take pre-made material split it to channels, modify and/or ignore them, and connect to Make Material and plug it to Material input in Surface node. Useful for learning how material works.
- Normal Pass node. It reads spot normal in world coordinates space and converts it to color space. It should be connected to Diffuse Shading input in Surface node.
- Normal Pass shader. Similar to Normal Pass node, but implemented as shader.
- Setup Normal Pass tool. It scans the all objects in scene, the all surfaces, and applies Normal Pass shader in one click.
