Hi,
I am new to MaterialX with houdini and I am trying to randomize the texture multiplier with Attribure Randomize.
How do you read the Vertex Attribute to assign the value?
I couldn't find the Mtlx node for it.

Thx

either usdprimvarreader or geompropvalue should work. The first one will only work with karma.
