Height to SSbump Generator | Substance Designer Node (SBS)

NOTE: Support for this node is currently discontinued as Substance licensing isn't cheap and I've since moved on to paid work to be able to sustain myself. This node will continue on the "Pay what you want" model, however, please consider donating.

A generator for Valve's self-shadowed bump mapping, integrated into Substance Designer for a faster workflow.

• Featuring several parameters to control height, optional hard shadows, length, attenuation, and ambient light intensity.
• Results in near real-time using Substance Designer's GPU-driven RT shadow and ambient occlusion nodes.
• Sharper, higher-fidelity outputs than with Valve‘s command line tool.

Current version: 1.1.0 for Substance Designer 12.1.0 and onward.

Known Issues:

• Height map inputs using lossy or compressed formats like .jpg will result in artifacts caused by bad colour space conversion (Thanks to @glassbottommeg for the explanation). 16-bit PNG image inputs tend to generate the best results.
• Harsh changes in height will sometimes result in Peter Panning of ray-traced shadows. Unfortunately, this is a bug with Substance's RT shadow node that will hopefully be fixed in a future release.

Changelog:

• 1.0.0: Initial release
• 1.1.0: Added parameter descriptions, specular highlight control, corrected output gamma, and fixed ambient light intensity over brightening the output.
