Runtime spawned Characters w Morph Targets do not Render Materials, unless..

Imported characters with head Morph Targets, spawned at runtime, only render materials at runtime if the material option Uses Morph Targets is checked. However, these characters only have morph targets for the head, and were imported with “import morph targets.”

These character entities were created with Character Creator 3.04, prior I only had to toggle the “Uses Morph Targets” option for the head specific materials (Characters created with CC3.01 and UE4.21.1). Since I also upgraded from 4.21.1 to 4.21.2 it is unclear if these adjustments are related to CC3 or UE.

It is certainly a bug, since you should only have to toggle the uses morph targets for materials which actually contain them.
