Sequencer character looks weird. Help!

My character looks normal in ue4, even when I import this into sequencer it looks good too but after adding animation to it, it looks ugly.

Now, here is a point. I made the character bigger than it was before, not inside UE4 but inside Maya. 2 images are attached to show you what the issue is. Please help me out. First one (Nice) is skeletal Mesh view and another one (ugly) is animation view

Edit: Here is the image link.

Problem was with virtual texturing. I turned it on and the problem is gone. Project settings>Rendering>Virtual texturing support>turn on or tick or mark the blank box.
