The change was made to avoid a crash
that could possibly occur with
Skeletal Meshes with more than 75
bones or more than 4 influences per
vertex. As such, these types of
skeletal meshes are no longer rendered
in Mobile Preview. These skeletal
meshes should render on ES3.1 however.
So how do we upgrade the mobile preview to ES3 mode? Limiting functionality and introducing a new defect was really the best way of addressing the crash?
