The FXV2 shader system handles SPIR-V transpilation by using the shadlang_backend_spirv backend to convert Shadlang shader code into SPIR-V bytecode for Vulkan pipeline integration. This process enables runtime compilation and loading of shaders directly within the Orkid engine.
The FXV2 file format defines shader techniques, passes, uniform blocks, and Shader Storage Buffer Objects (SSBOs) for the Orkid engine. These elements are parsed during the runtime loading workflow to configure Vulkan descriptor sets and shader resource bindings.
Integrating FXV2 shaders into a Vulkan renderer involves using the fx_pipeline and vulkan_fxi_load components to parse the FXV2 file format and load the resulting SPIR-V shaders. This pipeline manages shader module creation and descriptor set layout mapping for the rendering engine.
The Orkid FXV2 shader system uses Shadlang, its own shading language implemented in shadlang_impl, rather than standard GLSL. Shadlang code is subsequently transpiled into SPIR-V for execution on Vulkan hardware through the backend pipeline.
Techniques and passes in the FXV2 shader compilation pipeline define multiple rendering stages and variants within a single FXV2 file. The pipeline processes these configurations to generate corresponding SPIR-V shader modules for each pass required by the Vulkan renderer.
FXV2 shader loading failures in the Vulkan runtime often stem from errors in the fx_pipeline or vulkan_fxi_load parsing stages, such as malformed uniform blocks or invalid Shadlang syntax. Consulting the shadman and fx_pipeline references helps troubleshoot format and interface mismatches.
