Hey, I’ve spent a while developing a plugin for Blender, that among other things, can help process and batch export assets ready for Unreal Engine 4, augmenting the in-built FBX exporter. It’s called Capsule, and it can automate the export of hundreds of objects in a scene with a single click, with Export Lists, re-usable Export Presets, automated export organisation tools and a bunch of other neat things.

FEATURE LIST
Batch Exports - Mark hundreds of objects and groups in a scene for export, and export them all with one click.
Export Origin Editing - The plugin can automatically assign the origin point of your exports to the origin of your models rather than the scene, or whatever point you need it set to.
Export Lists - Get an overview of all objects prepared for export, and quickly change their settings from the list.
Export Presets - Create detailed sets of export settings that define how your objects and groups get filtered and processed into FBX files, and that can be simply applied to objects and groups in the scenes.
Tags and Passes - Passes let you export your objects and groups in multiple ways, creating a separate FBX file for each pass, whereas Tags let you define automatic filtering rules that make passes even more powerful.
UE4 Tools - The plugin includes a special, in-built Unreal Engine 4 preset that ensures exported models appear exactly as they do in Blender, while providing a few extra features, that I hope to expand on in the future.
If you have any issues in using it, or any other questions, suggestions or bugs, feel free to post and i’ll help you out
