UE4 not retaining BP settings with Hairworks?

Hiiii!

Have been struggling with issues with saving blueprints with Hairworks maps and settings. On loading the document settings seem to be lost and maps unloaded.

Also on loading the document am having intermittent collision issues.

Strangely this seems to be the case with Nvidia’s Hairworks viewer as I haven’t figured out how to save these settings either. I had kind of assumed they would be baked into the imported hairworks apx file?

Wondering whether this might have something to do with the engine build. It’s the new Hairworks integration (4.12.4) compiled from Github source. I’m a bit of a newb, so haven’t been able to merge the new hotfix with this version - would this perhaps fix my problems?

Thanks in advance if anyone has any clues or experience with hairworks and Ue4!!

in the Hairviewer, go to the Hairworks menu and choose save Hair. This saves your settings to the hair file you have loaded into the viewer. Then when you bring it into Unreal, you should have those settings.
