uExport: A Simple Maya Tool for Exporting to UE4

I posted the skeleton of this a while ago in the post “Why does everyone write their own FBX exporter?“, many people asked me for the exporter over the years and I sent it to them. Since that post, uExport has become the way we get all characters into UE4 at Epic. It’s been crazy to see this little fledgling tool, developed largely in spare time to allow us to export non-A.R.T.v1 rigs (like the kite and deer in the first demo I worked on at Epic) become something we rely on so much.

It’s here on GitHub, there’s a lot more info in the readme.

Simple Runtime Rigging in UE4

This is something that I found when cleaning my old computer out at work this week after an upgrade. This is an example of using a look at controller and a blendspace to drive a fleshy eye deformation in UE4 live at runtime.

This is the technique Jeremy Ernst used on Smaug’s eye in the demo we did with Weta over a year ago. Create a 2d blendspace for the eye poses. Export out left, right, up, down poses and connect them:


Grab the local transform from the eye, and set two vars with it:


Create a Look At Controller and integrate the blendspace:
