Metahuman Fingers warp after exporting from sequencer HELP

I’m working with metahumans at work and we’ve created our own using the metahuman creator and that is submitted through perforce,

To make animations for this, i have my own metahuman character created in exactly the same fashion, to animate with the sequencer and control rig. this is separate from our engine, but the same version etc

In the level sequence when animating the hand position looks absolutely fine - no issues whatso ever. Once i’ve done my work with animating i then export the time character from the time line using these settings.

the exported result - does not reflect what I have in the sequencer, fingers visibly deform incorrectly and almost bend like noodles

i’ve even tried retargeting this result to the same character and same result

i’ve even tried importing and retargeting animations from city sample to our metahuman and the fingers are with in reason acting as expected

ive had someone online suggest its a virtual textures missmatch but i cant seem to find any documentation about this

Please help my baccon is on the line
