UMediaTexture

Implements a texture asset for rendering video tracks from [UMediaPlayer](API\Runtime\MediaAssets\UMediaPlayer) assets.

API > API/Runtime > API/Runtime/MediaAssets

Implements a texture asset for rendering video tracks from UMediaPlayer assets.

note: derives directly from UTexture, not from UTexture2D or UTexture2DDynamic maybe should have been UTexture2DDynamic?
