3.19.2

This release is the last step in preparations for a new deferred rendering pipeline - terrain now supports rendering of multiple material layers in a single draw call. Currently only the unlit terrain shader can benefit from this due to the limited amount of available texture samplers. Some new utilities and fixes are included in this release as well, like for example ability to capture directional light's shadow map from its position instead of from the camera's position, which is handy for certain styles of games.

Changelog:

• Added new property LayersPerDrawCall to BBMOD_TerrainShader, which is the number of terrain layers that the terrain shader can render in a single draw call.
• Added new property MaxLayers to BBMOD_TerrainShader, which is the maximum number of terrain layers that the terrain shader supports.
• Added new macros BBMOD_U_TERRAIN_BASE_OPACITY_0..BBMOD_U_TERRAIN_BASE_OPACITY_2, which are the names of fragment shader uniforms of type sampler2D that hold a texture with base color in RGB channels and opacity in the A channel for the first, second and third terrain layer rendered in a single draw call.
• Added new macro BBMOD_U_TERRAIN_BASE_OPACITY, which is a common part of names of the BBMOD_U_TERRAIN_BASE_OPACITY_[N] uniforms, which only append a number to it.
• Added new macros BBMOD_U_TERRAIN_NORMAL_W_0..BBMOD_U_TERRAIN_NORMAL_W_2, which are the names of fragment shader uniforms of type sampler2D that hold normal smoothness/roughness texture for the first, second and third terrain layer rendered in a single draw call.
• Added new macro BBMOD_U_TERRAIN_NORMAL_W, which is a common part of names of the BBMOD_U_TERRAIN_NORMAL_W_[N] uniforms, which only append a number to it.
• Added new macros BBMOD_U_TERRAIN_IS_ROUGHNESS_0..BBMOD_U_TERRAIN_IS_ROUGHNESS_2, which are the name of fragment shader uniforms of type float that hold whether the first, second and third terrain material layer uses roughness workflow (1.0) or not (0.0).
• Added new macro BBMOD_U_TERRAIN_IS_ROUGHNESS, which is a common part of names of the BBMOD_U_TERRAIN_IS_ROUGHNESS_[N] uniforms, which only append a number to it.
• Added new macros BBMOD_U_SPLATMAP_INDEX_0..BBMOD_U_SPLATMAP_INDEX_2, which are the names of fragment shader uniforms of type int that hold the index of a channel to read from the splatmap for the first, second and third terrain layer rendered in a draw call.
• Added new macro BBMOD_U_SPLATMAP_INDEX, which is a common part of names of the BBMOD_U_SPLATMAP_INDEX_[N] uniforms, which only append a number to it.
• Shader BBMOD_SHADER_TERRAIN_UNLIT now supports rendering of up to 3 material layers in a single draw call.
• Added new macro BBMOD_U_BASE_OPACITY, which is the name of a fragment shader uniform of type sampler2D that holds a texture with base color in RGB channels and opacity in the A channel.
• Struct BBMOD_MaterialPropertyBlock can now also override the base opacity texture using the new BBMOD_U_BASE_OPACITY macro.
• Added new property ShadowmapFollowsCamera to BBMOD_DirectionalLight, which if set to true, then the shadowmap is captured from the camera's position instead of from the directional light's position. Default value is true for backwards compatibility.
• Added new property EnableShadows to BBMOD_ReflectionProbe, which if set to true, then shadows are enabled when capturing the reflection probe, which takes longer to render. Default is false.
• Fixed camera exposure setting being used also when capturing reflection probes, which effectively caused the exposure to be applied twice, making the scene brighter or darker than it should be.
• Fixed method render of BBMOD_StaticBatch crashing due to using BBMOD_RenderQueue incorrectly.
