Thanks for your patience, Patrick, and thanks for the feedback.
All the best
I can't reproduce this here.
I took a plane and made it editable.
Use Fields - checked.
I placed a Sphere field in the list.
Unchecked the Filed option.
Deleted the Sphere Field (not needed)
The values stay the same.
Since you mentioned Deformed and Non-Deformed.
I can't tell you anything else without a Project file (reduced to the problem); only check with tech support.
You're very welcome, divide-load.
I'm glad you got it working for your pipeline.
My best wishes for your project.
Thank you, Bar3nd,
It sounds like you found a workable solution. If the per frame generating of data isn't slowing down the process, then that is certainly great.
You're very welcome, family-flow.
I assume it works for you.
My best wishes
I have answered in the old forum.
I prefer project files over images and screen captures.
FBX has no concept of Bend Deformers, hence the need to create a PLA for that.
