We demonstrate the minimal setup required to use Unreal's Animation Budget Allocator. This plugin allows the equivalent of LODs to be applied to skeletal mesh animations.

In this article we delve into Blueprint Nativization, a relatively new feature of UE4 that offers significant performance improvements for many projects. Sadly, it often doesn't work out of the box - we've spent some time fixing and improving it for a particular project that we were working on. We have a LOT of changes to present here - some of which have already been implemented into UE4.

We found quite a large leak within Apex 3.4 (currently used in Unreal Engine 4, amongst others) - in a relatively short run of the title that we were working on, we saw over 150mb of leaked memory. Here, we present some changes that will fix this

We took a look at the inlining of a certain part of the codebase and were shocked with what we found... we then went about improving it

We present an optimization that removes a significant amount of memory churn from the animation code

Here we implement a scratch buffer to reduce temporary memory churn passing through PhysX
