Steps to Reproduce
We noticed we are unable to add attach tracks when there’s an additive transform track on actors/cameras. For those problematic assets they tried baking the 2 transform tracks and after removing the 2 tracks, and we’re able to get the attach to work. Would it be possible to get attach track work with additive tracks, or are we possibly using them incorrectly?

Was not able to repro locally. Waiting on some more detailed information. :slightly_smiling_face:

Hey Joshua, this workflow is unsupported at this time. I put in a JIRA for future consideration, but for the near term, the recommendation is to use constraints for this use case.

Thanks Shaun - adding some further context in here for posterity.

Specifically, setting the attach options to Preserve Current/All while also having an additive transform track is what causes this issue producing an empty attach track. If this mode is set to None, it functions normally.
