This release adds support for rendering models with baked lightmaps using secondary UV channel. Additionally fix of specular highlights intensity when using specular color textures is also included in this release.

Changelog:

BBMOD CLI:

  • Added new option --disable-uv2 (-duv2), using which you can disable export of second UV channel (if defined). This option is true by default (second UV channel is disabled).
  • The _log.txt file created during model conversion now describes vertex format of each mesh.

GML API:

Core module:

  • The first argument of BBMOD_VertexFormat's constructor can now be a struct with keys called after properties of BBMOD_VertexFormat and values true or false, depending on whether the vertex format should or should not have the property.
  • Added new property TextureCoords2 to struct BBMOD_VertexFormat, which tells whether the vertex format has a second UV channel.
  • Added optional argument _versionMinor to bbmod_vertex_format_load, which is the minor version of a BBMOD file that the vertex format is being loaded from.
  • Added new functions bbmod_light_ambient_get_affect_lightmaps and bbmod_light_ambient_set_affect_lightmaps, using which you can get/set whether the ambient light affects materials that use baked lightmaps. By default this is enabled.
  • Added new property AffectLightmaps to struct BBMOD_Light, using which you can enable/disable the light for materials that use baked lightmaps. By default this is enabled.

DLL module:

  • Added new method get_disable_uv2 to struct BBMOD_DLL, using which you can check whether second UV channel is disabled.
  • Added new method set_disable_uv2 to struct BBMOD_DLL, using which you can enable/disable second UV channel.

Lightmap module:

  • Added new module - Lightmap.
  • Added new struct BBMOD_LightmapShader, which is a wrapper for shaders used by lightmapped materials.
  • Added new struct BBMOD_LightmapMaterial, which is a material that can be used when rendering models with two UV channels, the second one being used for lightmaps.
  • Added new macro BBMOD_VFORMAT_LIGHTMAP, which is a vertex format of models with two UV channels, the second one being used for lightmaps.
  • Added new macro BBMOD_SHADER_LIGHTMAP, which is a shader for rendering models with two UV channels, the second one being used for lightmaps.
  • Added new macro BBMOD_SHADER_LIGHTMAP_DEPTH, which is a depth shader for lightmapped models with two UV channels.
  • Added new macro BBMOD_SHADER_LIGHTMAP_INSTANCE_ID, which is a shader used when rendering instance IDs for lightmapped models.
  • Added new macro BBMOD_MATERIAL_LIGHTMAP, which is a material for models with two UV channels, the second one being used for lightmaps.
  • Added new functions bbmod_lightmap_get and bbmod_lightmap_set, using which you can get/set the default lightmap texture used by all lightmapped materials (unless they override it).
