Skeletal meshes do not render or animate properly on the Xiaomi Redmi 6 (PowerVR GE8320) when using OpenGL ES3.1.
This issue changed a bit from 4.19 to 4.20. In 4.19, the skeletal mesh seems to of collapsed on itself and does not render properly at all. In 4.20 and onwards, the issue seems to be mostly with animations.
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-66009 in the post.
