The game is using nanite meshes though. For general limitations and possible issues please read
this topic.
I've updated specific build to somehow handle editor assets or assets from previous engines, usually present in Movies folder. It allows to perform animations search or full scan from the root game folder without crashes, but preview or export of such assets is not possible anyway. There was already an attempt to handle them, but without much samples it didn't work well, which should be fixed now.
