ShaderReflectionInfo MayaFlux::Portal::Graphics::ShaderFoundry::get_shader_reflection

(

ShaderID

shader_id

)

Get reflection info for compiled shader.

Parameters

shader_id

ID of compiled shader

Returns

Reflection information

Extracted during compilation if enabled in config. Includes descriptor bindings, push constant ranges, workgroup size, etc.
