The morph functionality fails to change when the skinned mesh contains more than one UV channel in a Customizable Object.
A sample project demonstrating this issue is attached.
The project includes two skinned meshes — one with a single UV channel and another with two UV channels. Each mesh has an assigned morph target.
Additionally, there are two customization instances: CO_Cube_1uv_Inst and CO_Cube_2uv_Inst.
When modifying the parameter 'Param', the morph updates correctly in CO_Cube_1uv_Inst but does not update in CO_Cube_2uv_Inst.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-349204 in the post.
