at least i ve managed to found a way to project details (my issue was the retopology that i ve used to project details), findind the way to project those details, now im stuck at the vector displacement work on maya, this is my best try, but i m having those artifacts in the mesh.
any thoughts pls, tks in advanced.
my zbrush config
Hi @johiko
There are many things that can go wrong with displacement display between Zbrush and a third party application. The process requires expertise in your target application as much as Zbrush, as every program does things a different way. I’m just saying this so you understand problems like these are perfectly normal and there’s a learning process there, and also so that you understand that the exact settings required to get good displacement results are something that also need to be studied in resources dedicated to your target application.
Thanks for doing your best to take screenshots and document your settings, but there are many opportunities for things to go wrong throughout the entire process. For instance, from your previous post I know that these meshes were imported into Zbrush, and not created there.
Was a morph target stored and switched to prior to map generation? The very act of subdividing a mesh will subtly alter a mesh at every level of subdivision, even the lowest. So if you import a mesh , subdivide it , and then generate a displacement map for it, that map is being generated for the new version of that mesh that was changed when you subdivided it. Not a problem if you then export the new base level of subdivision and apply the map directly to it, but if you are applying the map to the original mesh there will be a mismatch , enough to cause issues in many cases.
The way to get around this is to store a Morph Target of the original, unaltered mesh, and switch to it prior to map generation. That way the map is being generated FOR that original mesh, and not a subtly altered version. The process is described here in the Multi Map Exporter documentation, and elsewhere:
These kinds of problems are a pain, but they are a natural part of the learning process. Don’t get discouraged if most people are unwilling or unable to offer advice on it. It is extremely difficult to troubleshoot someone else’s pipeline based on limited information. You need to be familiar with every aspect of how the mesh was created and handled, as well as be an expert on the target application, and not every Zbrush user works with the same programs.
Good luck!
tks bro, right now im on that crazy horse, im trying to use the morph target, but im still getting those artifacts (dunno if those are pieces of the final retopo), im still searching for the flipandswitch values and tangent aswell, im reading as much as i think it could works.
i ll let you know, if you have some extra thoughts, pls.
tks again
i ve managed to make it works, i ve used the vector displacement map subpallete and voila
i ve loaded the project where i was sculpting and used GOZ to send the mesh to maya and return it to zbrush with the maya data; i ve used vd SUV and vd NORMALS and a 32bit mp, to know what kind of flipandswitch i ll need to use, i ve loaded the vector displacement map diagnostic, 47 is the perfect sphere.
Congrats for sorting that out! I’m glad you were able to solve your issue.
