We are running into an issue where when we add a skeletal mesh created using Character Creator 3 Pipeline Extension into Unreal where the apk build for Android ASTC crashes during launch on the Oculus Quest hardware.

At first we were receiving an error that the skeletal mesh had too many bones for our target platform, so I began using the Character Creator 3 Game Base Model feature which reduces models and prepares them for VR/AR. After importing this new model into a new VR project in the Motion Controller Map and packaging we had no errors returned. However, the apk crashes upon launch in the hardware. The VR template launches without the model, but once it is added the crash is introduced. Aside from the conversion done in CC3 to reduce the model, no additional work is being done to the baseline model in the software.

I suppose we are looking for more insight on building to the Quest from UE4 and implementing models generated from the Character Creator 3 Pipeline Extension. We are also using the CC shader plugin in our projects for importing the FBX skeletal mesh.

Thank you for your time and consideration. -Ernie
