Is there guidance for the Metal Shader Converter?

The skill outlines the workflow for using Apple's official tool to convert DXIL (compiled HLSL) into Metal libraries for high-end gaming features.

Can this help with Metal buffer alignment issues?

Yes, it includes specific guidance on 16-byte alignment requirements for float3 and float4 types to ensure correct CPU-GPU memory sharing.

Does this skill support HLSL conversion?

Yes, it provides detailed mappings for HLSL types, semantics, and functions to their Metal Shading Language (MSL) equivalents.

Does it cover OpenGL view setup?

Yes, it provides a direct mapping from legacy OpenGL views like NSOpenGLView and GLKView to the modern MetalKit MTKView.
