Static mesh Morph target error (error X3018: invalid subscript 'TexCoord_Unflipped')

Hello,
I got an error when I export a material from older to new version of unreal 4.26.2 Project. Problem causing from StaticMeshMorphTarget node when I’m using “MorphTarget1 WPO” and when I’m selecting “MorphTarget1Normals” then no error but got different output. But same material run perfectly on older projects which run on same version 4.26.2.

Error "[SM5] /Plugin/FX/Niagara/Private/NiagaraSpriteVertexFactory.ush(407,25-56): error X3018: invalid subscript ‘TexCoord_Unflipped’
"

  • did not find any options to add screenshots.
