libd3dcompiler

Wraps d3dcompiler_47.dll with shims to run it as if it were a native Linux shared library. Primary use case for me is enabling cooking SM5/FXC shaders for Windows from Linux editor. Also includes Rust bindings and CLI for compiling to and inspecting DXBC shader blobs.

Usage

Requires d3dcompiler_47.dll be obtained and dropped in repo root.

CLI

d3dcrs compile shader.hlsl -e main -t ps_5_0 -o shader.dxbc
d3dcrs disasm shader.dxbc
d3dcrs reflect shader.dxbc
d3dcrs strip shader.dxbc -o stripped.dxbc
