Exporting OBJ low res

Hi all,

I’ve got an issue when exporting a .obj file to Procreate.

I’ve got a high res object which has been voxel merged.
When I bring it into Procreate, its geometry appears to have been decimated considerably. Is this normal? why is it doing this? Is there a way around it so that it exports as it looks in Nomad Sculpt?
