Changelog 3.8.0

This release mainly unifies default and PBR shaders and materials by merging them into one and supporting features from both. This means you can now use the default shaders and materials with both specular color & smoothness and metallic & roughness workflows. The default shaders and materials now also support emissive and subsurface textures. All contents of the PBR submodule are now obsolete and they will be removed in a future release. Please use the default ones instead. Shaders used for rendering gizmos were accidentally changed in the last release, so these have been fixed. Further fixes of model rendering on some Android devices are also included in this release.

GML API:

Core module:

  • Moved properties NormalRoughness, MetallicAO, Subsurface and Emissive and methods set_normal_roughness, set_metallic_ao, set_subsurface and set_emissive from struct BBMOD_PBRMaterial to struct BBMOD_DefaultMaterial.
  • Moved methods set_normal_roughness, set_metallic_ao, set_subsurface and set_emissive from struct BBMOD_PBRShader to struct BBMOD_DefaultShader.

Rendering module:

PBR submodule:

  • Struct BBMOD_PBRMaterial now inherits from BBMOD_DefaultMaterial.
  • Struct BBMOD_PBRMaterial is now obsolete, please use BBMOD_DefaultMaterial instead.
  • Struct BBMOD_PBRShader now inherits from BBMOD_DefaultShader.
  • Struct BBMOD_PBRShader is now obsolete, please use BBMOD_DefaultShader instead.
  • Macro BBMOD_SHADER_PBR is now obsolete, please use BBMOD_SHADER_DEFAULT instead.
  • Macro BBMOD_SHADER_PBR_ANIMATED is now obsolete, please use BBMOD_SHADER_DEFAULT_ANIMATED instead.
  • Macro BBMOD_SHADER_PBR_BATCHED is now obsolete, please use BBMOD_SHADER_DEFAULT_BATCHED instead.
  • Macro BBMOD_MATERIAL_PBR is now obsolete, please use BBMOD_MATERIAL_DEFAULT instead.
  • Macro BBMOD_MATERIAL_PBR_ANIMATED is now obsolete, please use BBMOD_MATERIAL_DEFAULT_ANIMATED instead.
  • Macro BBMOD_MATERIAL_PBR_BATCHED is now obsolete, please use BBMOD_MATERIAL_DEFAULT_BATCHED instead.
  • Added new macros BBMOD_ShPBR, BBMOD_ShPBRAnimated and BBMOD_ShPBRBatched for backwards compatibility purposes. These evaluate to BBMOD_ShDefault, BBMOD_ShDefaultAnimated and BBMOD_ShDefaultBatched respectively.

Sky submodule:

  • Moved macro BBMOD_MATERIAL_SKY from the PBR submodule into a new Sky submodule, since the PBR submodule is going to be removed in a future release.
