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.

3.19.1

This path release fixes BBMOD CLI not working on Windows.

Changelog:

• Fixed BBMOD CLI not working on Windows because of corrupted memory.

3.19.0

In this release terrain mesh is split into chunks of configurable size and you can control how many chunks to render from the camera's position. Using this you can create larger terrains and draw just a portion of them to save on triangle count. The terrain now also supports a color map, which multiplies the base texture. Terrain material layers were reworked as a preparation for a deferred rendering pipeline. Please read the following changelog thoroughly before upgrading to this version.

Changelog:

• Added new property Colormap to BBMOD_Terrain, which is a texture to multiply the terrain colors with.
• Added new macro BBMOD_U_COLORMAP, which is the name of a fragment shader uniform of type sampler2D that holds the color map texture.
• Added new property ChunkSize to BBMOD_Terrain, which is the width and height of a single terrain chunk. Terrain mesh is now split into chunks which consist of ChunksizexChunksize quads.
• Added new optional argument _chunkSize to the constructor of BBMOD_Terrain. This is the width and height of a single terrain chunk. Defaults to 128.
• Added new property Chunks to BBMOD_Terrain, which is a grid of vertex buffers, each representing an individual terrain chunk.
• Added new property ChunkRadius, which is the radius (in chunk size) within which terrain chunks are visible around the camera. Zero means only the chunk that the camera is on is visible. Use infinity to make all chunks visible. Default value is infinity.
• Property VertexBuffer of BBMOD_Terrain is now obsolete! It was replaced with the new Chunks property.
• Added new property Material to BBMOD_Terrain, which is the shader used when rendering the terrain. Default is BBMOD_MATERIAL_TERRAIN.
• Added new struct BBMOD_TerrainLayer, which describes a material of a single terrain layer.
• Entries in BBMOD_Terrain.Layer should now be of Struct.BBMOD_TerrainLayer type instead of Struct.BBMOD_DefaultMaterial!
• Added new struct BBMOD_TerrainShader, which is the base class for BBMOD terrain shaders.
• Shaders BBMOD_SHADER_TERRAIN and BBMOD_SHADER_TERRAIN_UNLIT are now constructed from BBMOD_TerrainShader.

3.18.1

This is a small patch release that mainly fixes dynamic batching that was broken in 3.18.0.

Changelog:

• Fixed dynamic batches rendering only a single instance of a model.
• Fixed method present of BBMOD_BaseRenderer, which did not reset the world matrix to identity before drawing surfaces.

3.18.0

This release mainly brings improvements to BBMOD CLI by adding export of materials to *.bbmat files and conversion from Y-up space to Z-up space. These are currently experimental features and they may not work in all cases. BBMOD CLI now also supports conversion of entire folders of models to the BBMOD format.

Changelog:

• Added new option --export-materials (-em) to BBMOD CLI, using which you can enable/disable export of materials to .bbmat files. This is an experimental feature and it is by default disabled!
• Added new method get_export_materials to struct BBMOD_DLL, which checks whether export of materials is enabled.
• Added new method set_export_materials to struct BBMOD_DLL, which enables/disables export of materials.

3.17.2

This small release mainly brings a new type of render queue that specializes in rendering multiple instances of a single mesh, where each instance uses the same material. This new render queue can render such meshes faster than the regular one. Additionally, submitting and rendering models now uses cache for node transformations, which decreases number of operations required before a mesh is submitted/rendered and hence increases performance. Building terrain meshes was also optimized.

Changelog:

• Added new interface BBMOD_IMeshRenderQueue, which is an interface for render queues that can draw meshes.
• Replaced arguments _vertexBuffer, _vertexFormat, _primitiveType and _materialIndex of methods DrawMesh, DrawMeshAnimated and DrawMeshBatched of BBMOD_RenderQueue with a single _mesh argument, which is the Struct.BBMOD_Mesh to be rendered!
• Struct BBMOD_RenderQueue now implements the BBMOD_IMeshRenderQueue interface.
• Fixed methods BBMOD_RenderQueue.DrawMeshBatched not setting uniform BBMOD_U_MATERIAL_INDEX.
• Added new struct BBMOD_MeshRenderQueue, which is a render queue specialized for rendering of multiple instances of a model, where all instances are using the same material. You can use this instead of BBMOD_RenderQueue to increase rendering performance.
• Methods submit and render of BBMOD_Model now use caching to increase rendering performance of models that are either fully static or fully vertex-skinned. Models that consist from both static and vertex-skinned meshes cannot utilize this cache.
• Greatly improved performance of method BBMOD_Terrain.build_mesh.

3.17.1

This release removes all RTTI mechanisms from BBMOD, as they were not used throughout the library and only unnecessarily increased memory consumption. All deprecated methods of BBMOD_RenderQueue were also removed. Some bugfixes and rendering optimizations are also included in this release. Please make sure to read this changelog thoroughly before updating to this version!

Changelog:

• Removed RTTI mechanisms from BBMOD: removed struct BBMOD_Class, macro BBMOD_CLASS_GENERATED_BODY and functions bbmod_is_class and bbmod_class_get_name! This means methods is_instance, implement and implements are also no longer available. Please make sure that you are not using any of these before upgrading to this version!
• Added BBMOD_IDestructible, which is an interface for structs that need to be manually destroyed to properly free used memory. Structs that previously inherited from BBMOD_Class and still need a destroy method now implement this interface. Structs that did not need the method but still had it, because they inherited from BBMOD_Class, now do not have the method and trying to call it will give you an error. To fix this, simply remove these calls.
• Optimized method BBMOD_MaterialPropertyBlock.apply, which was previously slowed down by using function variable_struct_get_names.
• Changed default value of property Mipmapping of all materials from mip_on to mip_markedonly to fix performance issues on some platforms. Please make sure to enable option "Generate mipmaps" in "Texture Groups" settings for texture pages that should have mipmaps.
• Reduced complexity of depth and ID shaders and possibly increased rendering performance on some platforms.
• Added new optional argument _depthBuffer to function bbmod_surface_check, using which you can configure whether a depth buffer should be created for the surface. Defaults to true.
• BBMOD no longer creates depth buffers for surfaces that do not need them (e.g. surfaces for post-processing effects). Likewise it also always creates depth buffers for surfaces that do need them (e.g. the application surface, cubemaps etc.).
• Removed all deprecated methods of struct BBMOD_RenderQueue!
• Added new render command BBMOD_ERenderCommand.SetGpuState, which sets the GPU state.
• Added new method BBMOD_RenderQueue.SetGpuState(_state), which adds a BBMOD_ERenderCommand.SetGpuState command into the queue.
• Added new render command BBMOD_ERenderCommand.SubmitRenderQueue, which submits another render queue.
• Added new method BBMOD_RenderQueue.SubmitRenderQueue(_renderQueue), which adds a BBMOD_ERenderCommand.SubmitRenderQueue command into the queue.
• Fixed methods DrawSpriteExt, DrawSpriteGeneral and DrawSpritePart of BBMOD_RenderQueue crashing because of wrong variable names.
• Fixed method BBMOD_Sprite.from_file_async passing Asset.GMSprite instead of Struct.BBMOD_Sprite into the callback function.
• Fixed method BBMOD_ResourceManager.load crashing when callback function is not provided.
• Fixed formula used in function bbmod_lerp_delta_time.
• Fixed gizmo, which still did not work in 3.17.0.

3.17.0

The main new feature of this release are reflection probes, which are used to capture surrounding scene at a specific position into a texture, which is then used for reflections. You can have as many reflection probes as you like, but currently only one reflection probe is used when the camera enters its area of influence. There is a smooth transition when changing from one reflection probe to other. BBMOD now also has material property blocks, which are useful in case you want to render multiple models using the same material and only change a few properties for each model. Using material property blocks should lead into better performance than creating a clone of a material for each model. Other noteworthy updates included are fixed Gizmo module, new commands for rendering sprites through render queues and new *Self/*Other variations of methods of vectors, quaternions and matrices, which instead of creating new structs store the result into self or a struct passed in as an argument, which makes them more garbage collector-friendly.

Changelog:

• Added an optional argument _format to function bbmod_surface_check, which is the surface format to use when the surface is created.
• Added new property Format to BBMOD_Cubemap, which is the format of created surfaces. Default value is surface_rgba8unorm.
• Added new property SurfaceOctahedron to BBMOD_Cubemap, which is a surface with the cubemap converted into an octahedral map.
• Arguments of _clearColor and _clearAlpha of method BBMOD_Cubemap.to_single_surface are now optional and they default to c_black and 1 respectively.
• Added new method to_octahedron to BBMOD_Cubemap, which converts the cubemap to an octahedral map.
• Added new function bbmod_vertex_buffer_load, which loads a vertex buffer from a file.
• For each method of BBMOD_RenderQueue that adds a render command into the queue there is now an equivalent function with an UpperCamelCase name (matching the command name defined in BBMOD_ERenderCommand). Please from now on use these methods instead of the original ones, as they are now deprecated.
• Added new members DrawSprite, DrawSpriteExt, DrawSpriteGeneral, DrawSpritePart, DrawSpritePartExt, DrawSpritePos, DrawSpriteStretched, DrawSpriteStretchedExt, DrawSpriteTiled and DrawSpriteTiledExt to enum BBMOD_ERenderCommand, which are render commands for drawing sprites.
• Added new methods DrawSprite, DrawSpriteExt, DrawSpriteGeneral, DrawSpritePart, DrawSpritePartExt, DrawSpritePos, DrawSpriteStretched, DrawSpriteStretchedExt, DrawSpriteTiled and DrawSpriteTiledExt to struct BBMOD_RenderQueue, which add respective commands into the queue.

• Added new member ReflectionCapture to BBMOD_ERenderPass, which is a render pass where objects are rendered into reflection probes.
• Added new method prefilter_ibl to BBMOD_Cubemap, which prefilters the cubemap for use with image based lighting.
• Materials BBMOD_MATERIAL_SKY, BBMOD_MATERIAL_TERRAIN and BBMOD_MATERIAL_TERRAIN_UNLIT now have a shader for the new BBMOD_ERenderPass.ReflectionCapture pass, so they are visible in reflection probes.
• Added new property RenderPass to struct BBMOD_Light, which is bitwise OR of 1 << render pass in which the light is enabled. By default this is BBMOD_ERenderPass.Forward and BBMOD_ERenderPass.ReflectionCapture, which means the light is visible only in the forward render pass and during capture of reflection probes.
• Added new enum BBMOD_EShaderUniformType, which is an enumeration of shader uniform types.

3.16.7

This release reconfigures Assimp and adds new options to BBMOD CLI and DLL to give you more control over model conversion.

Changelog:

• Reconfigured Assimp to do less post-processing on models by default, as the old settings could sometime cause issues and make the model unusable.
• Added new option --apply-scale (or -as) to BBMOD CLI, which applies global scaling factor defined in the model file if enabled. For backwards compatibility this is by default disabled.
