Hey I have been messing with Houdini and recently hit an issue I cannot seem to solve or find a solution too. It has to do with Relative References and References in general. So onto the bug Im hitting.

When I create a new scene and setup a Reference,(could be a connection between a node or a reference I expose to be able to control that attribute at a high level) the connects displays as Green in the tool bar. See Attached Image 1. However in my more complex of a scene that I have been tooling around with for a few days now all my References are now Bluish? See Attached Image 2.

I wasnt worried about this initially however it appears once this turned this Bluish color that the OTL no longer loads in Unity. It seems to work just fine in Houdini and updates as I have set it up to do so….?

Any Thoughts as to what is happening or what Im doing wrong?

they are Green when your timeline is on a keyframe for that expression and Blue when it's not
