Changelog
9.1.0
- Add new blending mode add_multiply: requires dual blending and then introduces a new output.
- Rendering states (blending modes, culling, etc.) can be conditionaly enabled in function of parameter values (specialized uniforms only).
- New lib-alpha-test.glsl library that contains alpha test related reworked parameters and alphaKill function. Previous lib-alpha.glsl library is kept for compatibility reasons.
- UI group, description and label of most library parameters have been updated.
- New Absorption color channel support.
- Translucency channel default value is now 1.0.
- Added new parameter in Subsurface scattering ( lib-sss.glsl) to toggle usage of translucency channel as scattering mask.
- Updated asm-metal-rough.glsl shader to support alpha test, alpha blend, translucency and absorption.
8.2.0
- Engine parameter environment_rotation in lib-env.glsl is replaced by environment_matrix. Allows more complex environment transformations.

7.2.0
- Add a new lib-coat.glsl library to help handling coating layer in the material.

2018.3.2

2018.3.0
- Add a new lib-pbr-aniso.glsl library to help visualizing anisotropic specular highlight
- Add a new lib-sparse.glsl library to help channel sampling by taking care of mipmaps availability
- Update shader libraries interfaces to take care of this safe sampling
- Deprecation: The previous functions based on the vec2 texture coordinates and the texture sampler have been deprecated (please use new signatures)
- lib-pom.glsl: Add a applyParallaxOffset function to simplify to use of parallax occlusion effect
- lib-random.glsl: Add a Blue Noise random value generator and temporal alternatives
- lib-sampler.glsl: Split all channel sampling helpers to have both value interpretation and sampling helpers
2018.2.0
- Surface shader API change: the shade function signature has changed, see surface-shader.glsl
- The shadeShadow function is no longer used and can safely be removed from custom surface shaders
- Add Subsurface Scattering support, see surface-shader.glsl and lib-sss.glsl for details
- lib-pbr.glsl: the pbrComputeBRDF function has been removed. See pbr-metal-rough.glsl example to know how to use the library now
- New engine parameters have been added: texture_blue_noise, aspect_ratio, camera_vp_matrix_inverse, environment_exposure, environment_rotation, fovy, main_light and screen_size. See all-engine-params.glsl for details
- Add the description metadata to provide tooltips for custom shader parameters
