BUG: Optitrack Unreal Engine 5.2 Retargeting Scale Bones Broken

Post by pdcsky »

Using Unreal Engine 5.2 with the latest Optitrack plugin.
I am able to get a live link feed - GOOD!

I'm also able to get the default mannequin of UE5 and talk to the live link - GOOD!

The animation blueprint for the mannequin is extremely simple. 1 Node.

In the Retarget Asset I have a custom OptitrackLiveLink Retargetting Asset.
Whenever I use a normal one, meaning an asset with all the default values and nothing changed, it works absolutely fine.

However there is an option at the very bottom called 'Scale Bones'

When I tick this, the mannequin completely breaks - BAD!

I don't believe this is how the 'Scale Bones' option is supposed to work.
In my mind it was going to scale the bones of the mannequin to match the bones of the Live Link skeleton.

Can you help Optitrack?

I ran into the same Issue in UE 5.3. Is there a roadmap when this will be fixed?
