This release brings an upgrade to the default shaders, which now support the specular color-smoothness workflow, as well as dynamic shadows from the directional light. Some refactoring of materials and shaders inheritance was required to enable this. If you only used the default materials (
BBMOD_MATERIAL_DEFAULT*), then this change should not affect your project at all. If you have created your own materials, please read the following changelog thoroughly to be able to update your code.
BBMOD_Coloras an argument. The variant with separate arguments for color and opacity is kept for compatibility purposes, but it should not be used anymore, as it will be removed in a future release!
BBMOD_DefaultMaterial.NormalSmoothness, which is a texture with tangent-space normal vector in the RGB channels and smoothness in the A channel.
BBMOD_DefaultMaterial.set_normal_smoothness, using which you can set the normal vector and smoothness to a uniform value for the entire material.
BBMOD_DefaultMaterial.SpecularColor, which is a texture with specular color in the RGB channels.
BBMOD_DefaultMaterial.set_specular_color, using which you can set the specular color to a uniform value for the entire material.
BBMOD_DefaultShader.set_normal_smoothness, using which you can set the
BBMOD_DefaultShader.set_specular_color, using which you can set the
BBMOD_DefaultShader.set_shadowmap, which is used to set uniforms
bbmod_ShadowmapNormalOffsetrequired for shadow mapping.
BBMOD_Shader, which is now the base class for wrappers of raw GameMaker shader resources.
BBMOD_BaseShaderis now base class for shaders with BBMOD-specific code. General-purpose code was moved to
bbmod_camera_set_zfar, using which you can configure the distance to the far clipping plane passed to shaders.
BBMOD_BaseShader.set_zfar, which is used to set uniform
BBMOD_Light, using which you can enable/disable lights without having to call appropriate set/add/remove functions.
BBMOD_ERenderPass.Id, which is a render pass during which can instance IDs be rendered into an off-screen surface.
BBMOD_Animation.create_transition, which did not round transition duration, causing errors in animation playback.
BBMOD_Color.Mix, which used inexistent variable name.
BBMOD_SHADER_DEPTH_BATCHED, which are shaders used when rendering scene depth.
BBMOD_Renderer.EnableShadows, using which you can enable rendering of dynamic shadows. Only materials with a shader defined for
BBMOD_ERenderPass.Shadowsrender pass can cast shadows!
BBMOD_Renderer.ShadowmapArea, which is an area around the camera captured by the shadowmap. Only models within this area will cast shadows.
BBMOD_Renderer.ShadowmapResolution, which is the resolution of the shadowmap. Must be power of 2.
BBMOD_Renderer.ShadowmapNormalOffset, which is used to offset vertices by their normal vector when sampling the shadowmap. Configure this value to remove artifacts.
