Hey all, I'm trying to grab an array of uniquevals for a prim intrinsic string attribute set of values from packed-alembic primitives.

If I have this in my primwrangle:


I am expecting to see an entry per primitive of the abctypename and an array of all the unique values - however whilst the primintrinsic attribute is read fine the array is not - it is empty.

I am using Houdini 18.0, and the documentation for ‘uniquevals’ reads:

attribute_name
The name of the attribute (or intrinsic) to read.

Any help appreciated,
Marb

I know this is ages later, but I wanted to say that I was also just looking for a solution to this and couldn't for the life of me figure out how to make it work.

It can be temporarily solved before SideFx fixes it, first copy the intrinsic attribute to prim, and then uniquevals it.:P
