Hi all,

I’m running into an issue when creating a Pose Driver node in my Post Process Anim Blueprint.

The Pose Driver compiles fine when there’s only a single pose, but as soon as I add a second pose, I get the following error.

In this example, my pose asset includes two poses, basically a “down” and a “default.” I realize the “default” pose isn’t strictly necessary, but I’m seeing the same issue with other Pose Driver setups that use multiple poses (e.g. up, down, left, right, etc.).

I’m working in Unreal Engine 5.5 with Pose Driver Connect. I used Asset Wrangler to generate the JSON and animated FBX files containing the pose data, and I followed the Pose Driver tutorial on this site exactly. This one:

Has anyone else run into this, or found a workaround?

Thanks!

Anyone looking for this Answer:

Switch “Solver Type” to Additive. I suspect the poses need to be solved additively in order for it to work in a post process Manner? If anyone knows the answer I would love to know.
