With the fifth Preview release of 4.11 now available to download from the launcher, developers can now check out the new animation updates including; marker based syning for animations and Anim Dynamics Skeletal Control for Animation Blueprints (a brand new self-contained and simple physics simulation node allowing for dynamic motion to be procedurally added to skeletal meshes without having to use a full physics solution),
If you would like to download Preview 5, head over to the "Library" section of the Unreal Engine tab in the Epic Games Launcher select "Add Versions", and choose 4.11 Preview 5. If you already have a 4.11 Preview installed, simply hit the upgrade button.
As always, you can read up on the fixes included in this release through this forum post from Stephen Ellis, and be sure to have a look at on the known issues list to see what's still outstanding.
