Why imported Skeletal Mesh's morph target name doesn't appear when adding in modify curve node in animation blueprint?

[janalteredverse]

hi

We are using UE 5.5 and Blender

we were able to see the morph target names from the skeletal mesh

but when we are already trying to get the names from the animation blueprint using the modify curve node, it doesn’t appear there

any advice on what or where did we go wrong? might be from exporting from blender or importing in UE? or other things?

any suggestions, comments, tips or answers are appreciated

thank you
