Compatible Nuke versions: 6.0 or later
Compatibility: Windows
Useful for realtime artists and as an alternative to Crazybump and simlar applications that use 2d filters to calculate normals.
Resolution should be the same as that of the image input (1 polygon per pixel!) for highest quality at the cost of long rendertimes.
Use Half or quarter of the image resolution for previews.
