Vray Displacement rendering vertices has black holes!!

[sazoman]

Hello everyone, I ran into a issue with Vray rendering Zbrush Displacement has holes were the vertices are. I am not sure how to word this correct so i attached a image. I also have attached some images of the setting also. The pocket mesh renders correctly without holes when displacement attributes are clicked off.  The faces normals are facing the correct way and vertex normals are green not yellow. I deleted history etc. Uvs are sewn together and placed correctly.  The mesh also has vray displacement created. I can Photoshop it and clean it up and to move forward but i really want to figure this out just in case this occurs again. Thanks again fellas i hope to hear from you guys soon.

Hi!

This looks as if not all faces are connected.

True but they are connected. I can attach it the geo so you can take a look? just add a vray displacement and render.

Hello just realized that you need the Zbrush Displacement to test this out. I been trying to attach the displacement with no success every time i attach and try to upload it saves the message and deletes attachment. The displacement is 512 the smallest zbrush makes not sure on how to give you the displacement to test this out. If someone can let me know that would be cool! thanks.

Hello still doing some test. I exported the mesh to another scene and build the displacement nodes for it and rendered it displayed correctly. Now after i created a vray displacement clicked render and now i get the the holes. I have a displacement question when you attach a zbrush displacement should you always create a "Vray  create a vray displacement node for selection correct"?  because without it the quality of the bump wont be has good correct? pocket_flap_noVrayDisplacement.jpgpocket_flap_WITH_VrayDisplacement.jpg

Hi!

There could be a problem with the displacement map itself, but the issue is more likely caused by the topology.

Your mesh is not clean, as you have edges connected to more than 2 faces (check at the borders of your UV maps).

This can break the subdivision needed for the displacement

Please clean up your meshes.
