Compatibility
Host Applications: mental ray and RenderMan
Operating Systems: Windows, Mac OS X and Linux
Architecture: 32-bit and 64-bit
Overview
Reverse ambient occlusion is a novel technique that can be used to improve texture painting or to mask specific areas in a layered shader.
This shader works like an ambient occlusion shader but offers the option to sample the interior of objects as well as the outside.
Usage
minRAO may be used to generate areas of wear, dust and dirt for example to help create wear and dirt around edges and corners. It works well as an alpha mask with baked textures or in combination with the minLayer shader.
Examples
- Ambient occlusion is reversed to show proximity inside object
- Used to quickly add subtle subsurface scattering
Compatibility
minRAO is compatible with mental ray and RenderMan on Windows, Mac OS X and Linux (32-bit and 64-bit).
