- AssetManager uses static assets ID from path hash - PipelineFactory creates Vulkan pipelines using PipelineConfig structure depending on AssetMaterial and creation flags - AssetMaterial describes pipelines (e.g. used shaders) - Materials are described with JSON in sources with path references to other assets - AssetMaterial is parsed from binary file with asset IDs in references - compile_config tool compiles material JSON file to binary file with path references replaced with asset IDs - Allocator supports type's constructors with arguments - NativeFileSystem: fixed empty bufferSize and buffer trash
