I need groom with rootUV，guides and group ID 3 attributes in UE5.
But I got problme about attribute when export the groom abc file from houdini.

after combine all the groom parts using 'merge'node,some of the attributes reset to default....but, you know ,the attributes are different from each group.you can't set them again after merge....
so far,this happened to width and rootUV attributes.
I got rootUV,lost groupID....got groupID,lost rootUV,sad...

do I have some other option with houdini to add attributes with rootUV,guides,and groupID correctly?
Is it a bug？
