CustomNodes in CustomizedUVs

Hi

I am working on a material that needs to perform some calculations at vertex level and then pass the result to pixel shader using CustomizedUVs.
It was all working fine till UE-4.21 but recently I upgraded to 4.23 and looks like I can not use custom nodes with customized uvs :frowning:

I was wondering if there’s any workaround for getting it to work on 4.23?

Error: [SM5] /Engine/Generated/Material.ush(1873,19-129): error X3004: undeclared identifier 'CustomExpression0’

Thanks!
