@Graphics and Games Engineer . Thank you for your reply. I tried to make a example file in Reality Composer Pro and load it in the code as follow. let shader = try ShaderGraphMaterial.load(named: "Material", from: "Untitled.usda", in: Bundle.main) But, it throws an exception. Can you make a example for me?

Really it's helpful link. btw when can I expect a full sample code for this video? Actually I tried to create MTLCommandBuffer and MTLRenderCommandEncoder inside the renderloop, but I am not sure how to submit the command buffer.

I found at here.
