Shit, sorry not scene change. Pose change. I set up poses in BodyLanguage, one of them has a OnPoseEnter trigger to set sim. Switching between poses does not trigger setsim properly, I get the message mentioned above instead.
I set up what should be the barest version of the scenario (otherwise blank scene, basic person, body language + simsetter, two poses, pose 1 triggers set sim, ui buttons to apply each pose) and wasn't able to replicate the issue. The plugin should only send this message if the variable "savedClothing" is null or empty, and "savedClothing" should always be set to the selected clothing item when Save Sim is applied, so off the top of my head I'm not sure what could be causing this.
Some extra troubleshooting steps:
1. Have you tried re-saving the sim in the plugin and then attempting the triggered load?
2. You said that applying the sim via the plugin's UI button works; did you try using the pose trigger directly after this, or alternate back and forth between the two at all to see if there was a change in behavior?
3. This feels like a dumb question, but you aren't triggering save sim as part of this, right?
Additionally: are you using the
Set Sim or
Queue Set Sim trigger when doing the pose change? Pose changes in general reset the clothing sim, so triggering
Set Sim at the same time won't do anything because it tries to apply the vertex position before the vertices are available to be set. I don't know if it would be related to the log message you're getting, but it's probably what should be done in this case anyway.
(Not sure if there's a way [functionally or policy-wise] to share the pertinent parts of the scene so I can poke at it directly, that would probably be the easiest.)
