[Unreleased]

[1.2.0] - 2019-07-24

Changed

• Moved to repository

• Switched to changelog markdown

• Re-defined basecolor to be in sRGB color space

• Set default basecolor to be 0.9 (which is 0.79 in linear space, a very bright white)

• Re-defined "alpha" as opacity factor Already was treated like it in three.js implementations, but not in Unity. Trying to remove discrepancies.

• Re-defined RGBA texture mapping's alpha channel to be alpha (in terms of opacity). Used for alpha clipping/testing as well

Added

• Texture mapping ORM: combined occlusion, roughness, metallic texture

• Transmission factor and IOR to allow specular transmissive materials (glass) Note: No explicit transmission color. The base color is used.

• Added occlusion strength (used in real-time when occlusion textures are present)

Removed

• Removed obsolete specular factor Referred to the specular-glossiness workflow, which is not supported
