UsdPrimVarReader authoring inputs:varname as token (should be string)

[robp-sidefx]

There is an issue in

USD-Fileformat-plugins/utils/src/layerWriteMaterial.cpp

Line 67 in d00097d

{ { "varname", getSTPrimvarAttrToken(uvIndex) } },

whereby the value for varname is being passed along as a token, but should be a string (this is noted elsewhere -

USD-Fileformat-plugins/utils/src/layerReadMaterial.cpp

Lines 233 to 235 in d00097d

	// Supports both string and token type values for the varname
	// string is the correct type, but token was added to support slightly
	// incorrect assets.

)

Quick fix proposal:

-                        { { "varname", getSTPrimvarAttrToken(uvIndex) } },
+                        { { "varname", getSTPrimvarAttrToken(uvIndex).GetString() } },
