Description

• Cleaned up standard shaders (Lambert, Standard, StandardPBR, Unlit)
  • Moved runtime branches to proper features (using the variant system)
• Fixed feature set not supporting permutations
• Fixed parallax mapping implementation
  • Bitangent had to be inverted (* -1.0) to be left-handed instead of right-handed
• Fixed normal mapping (bitangent was inverted too)

To-Do

• Fix TBN needs to be right-handed for normal mapping, but left-handed for parallax both needed to be left-handed

Breaking Changes

• u_EnableNormalMapping (used for runtime branching) has been removed in favor of the NORMAL_MAPPING feature (compile-time). Projects using this feature will need to be updated to use the NORMAL_MAPPING feature instead
