An interesting problem trying to use Blender particle hair with Daz models via the Daz Blender bridge (because Daz don't offer strand/particle hair with physics to the masses). Duplicated some mesh from the head to create a cap and added particle hair with dynamics. Nothings happens when you simulate. To debug I have eliminated all other assets from the file and also added a new UV sphere. With the same setup, hair dynamics on UV sphere works fine but hair on cap does not. Can anyone tell me why this is. File uploaded if you want to try it. Issue is the same in 2.83 and 2.92.
