how to replicate blender combine animations in godot

Godot Version

Godot 4.5.1

Question

I’ve animated a model with NLA tracks in blender. When exported to Godot I’m no table to combine the actions to replicate the animations correctly. I’m not sure if this down to my export settings or how the add and blend nodes work in godot. I’ve posted a video on reddit showing my set up

I’ve looked at the documentation for how Combining animation strips in blender works and how both the blend and add animation nodes in the godot editor work. It seams this issue might be caused by the two functioning differently from combine in blender. However I’m not sure as this doesn’t have an impact of FK animated tracks, only IK animations. Both of the tracks I’ve combined use IK handles to control the hands.

Just in case it is relevant, I’ve made these animations with Extrapolation set to none and Blending set to combine in Blender. I’ve noticed my animations won’t export unless I have the following Active strip settings in blender:

Extrapolation: Hold

Blending: Replace

I’ve checked the exported animations in godot, they match the tracks in blender when one track is active. There has to be a way around this. Would anybody happen to know of a solution?
