I'm not sure if my workflow is incorrect but I have found something a little odd with transferring groups with the Assemble SOP.

I was doing a sim and needed to use the rbdconfigure to set the active area. After that node however, some of my primitive groups I use to texture were either empty or had the wrong amount of primitives in them.

I googled around and found that most solutions were to make sure the Assemble SOP was transferring the groups. However the only thing that got it to work was to make sure the Transfer Groups field was completely empty… I had to unlock the rbdconfigure HDA and clear the fields. Now I have all my groups and everything is working fine…

As I said, not sure if I did something wrong further up the chain but maybe this is a bit of a PSA for anyone finding a similar issue.

Do you have a repro hip file I could take a look at? That'd be really helpful.

Cheers,
Nick

not a file, but should be easy to replicate
as mentioned here, it seems to me that Unpack SOP always transfers the groups from packed to unpacked regardless of the Transfer Groups parameter

Thanks Tamte, that makes sense - it wasn't clear that the groups had changed when unpacking - it does seem like a bug with the unpack SOP. Would you mind logging a bug?
