Does the mesh contain non-Z axis based displacement? If it doesn’t, then there is no need to use VDM. You can google for “UE4 vector displacement map” and find results.

Thx,This mesh have Z axis,My VDM map bake from Zbrush and Xnormal,I try someway from google or use VDM node from material,but the mesh always broke。
P1 is my material, P2 is VDM node.
