create_from_glsl_file()

bool MayaFlux::Core::VKShaderModule::create_from_glsl_file	(	vk::Device	device,
		const std::string &	glsl_path,
		std::optional< vk::ShaderStageFlagBits >	stage = std::nullopt,

	)

Create shader module from GLSL file.

Parameters

device	Logical device
glsl_path	Path to .comp/.vert/.frag/.geom file
stage	Shader stage (auto-detected from extension if not specified)
entry_point	Entry point function name
enable_reflection	Extract metadata
include_directories	Paths for #include resolution
defines	Preprocessor definitions

Returns

true if creation succeeded

Reads file, compiles GLSL → SPIR-V, calls create_from_spirv(). Stage auto-detection: .comp → Compute .vert → Vertex .frag → Fragment .geom → Geometry .tesc → Tessellation Control .tese → Tessellation Evaluation
