Groom physics enabled?
If yes , have a look at your physic capsules for the head !
If there is no physic actor for the MH HEAD , create one ( right click on the MH head/ create physical actor) , tweak the capsules and add the "physical actor" to the BP Character / groom / physical actor.
Now you have collisions with the MH Head.
I can do a speedy tutorial for you if you need.

Or does your groom has no physics enabled?




It’s the cc3 character I posted the other day, physics groom rods enabled, using cc3 physics asset, and have adjusted the capsule. It looks fine until I move camera to edge of frame and some strands disappear, looks like strand culling. The hair is 3 pieces, base, ponytail and bangs. Physics not enabled on base as per his documentation, just on tail and bangs.

Will do some more testing when I get home from work.

Yo, that worked...:P
Is it normal the import time is significantly longer when "Import Morph Targets" is ticked?

yes , but only when importing the whole CC3+,  because of the CC3+ shaders , be sure you ticked "default frame rate" ...
when importing animation only , it is very fast ...
Fastest way :
1. import only the CC3+ with morphs enabled ( no animations)
2. import all your animations to the same folder with unticked "import Mesh".

Hm, so, we don't use "Custom Sample Rate 60" anymore??
I thought this was the "lightning speed trick"...
