The 1st image shows an imported object from ZBrush with a displacement map, which displays a detailed surface.

The 2nd image shows the object after vdbfrompolygons nodes are added, and the detail is gone.

Why is this happening, and what setting can I change to bring back the detail?

Thanks

likely because you don't have UVs on the remeshed geo since displacement map relies on that

you may have some luck with Labs UV Transfer to transfer vertex uv attribute from original geo to remeshed geo

or alternatively you can create new UVs and bake the new displacement map

Many thanks, I will give it a go.

I have tried increasing the Res/Voxel Size on the VDBfrompolygons but anything over 0.002 crashes my system

Attached is an example of the setup
