IN-60376 Shader graph inputs directly connected to outputs don't work

[Alex_StudioDrydock]

Directly connecting a shader graph property to an output doesn’t work; the graph uses the property’s default value instead of using the material property.

A workaround is to route the property through a swizzle (or any other kind of) node.

It appears the incorrect USD being generated is:

float inputs:opacity.connect = </MaterialX/Materials/USD_MyShader.inputs/_Property.outputs:out>

when it should be:

float inputs:opacity.connect = </MaterialX/Materials/USD_MyShader.inputs:_Property>

Yes; I see the problem. We’ll get this fixed ASAP.
