Add more material examples (#257)
* Merge v1.1 development to main (#222) This changelist merges v1.1 development from dev_1.1 to main, in preparation for marking the release of OpenPBR v1.1. * Adding more material examples - Bumped MaterialX version from 1.38 to 1.39 on existing examples - Added new examples * - Added MIT Black * Color updates: - Updated all colors to ACEScg - All metals now have F82 as specular_color - Added a few more metals from Portsmouth's chart * Material updates: - Added SSS to Sclera and made it less red - Added LCD Display material - Added two variations of Light Bulb with different CCT * Material updates: - Added base_diffuse_roughness to Brick, Charcoal, and Sand - Made Velvet purple so it's more convincing * Updated roughness values * Removed a few materials that were less useful as examples * Renamed Polyurethane * Updated Blood material * Added Abbe value to Blood material * Updated IOR of Blood * - Updated coffee material * Split Honey into two materials, liquid and crystallized * - Updated Honey (Crystallized) roughness value --------- Signed-off-by: Adrien Herubel <AdrienHerubel@users.noreply.github.com> Co-authored-by: Jonathan Stone <jstone@lucasfilm.com> Co-authored-by: Adrien Herubel <AdrienHerubel@users.noreply.github.com>
