The followıng process has crashed Skeletal Mesh

The Problem is not the quality of model (is not mine, i take it on internet to test)

Is Why it work on Unity/UDK with animations included.

My question is why this happened on UE4 and on UE3 or Unity not?

If is necessary i have a model from same site i think from same “game” or modeller, and it work on UE4.
However for my purpose i try to remade it from scratch but is strange that model work on other engine and on UE4 not work.
Thanks Anyway :slight_smile:
