I want to DynaMesh and then polish my model, but it always looks bad. I tried import like STL, OBJ and FBX. Tried use ZRemesher , but it always went messy(but it worked with another model). So I just dunno what to do with this. Any advices ?
Hello @K10N0SP ,
This is hard surface geometry which has additional concerns and will require more special care than organic geometry. This looks to be finely detailed, end-stage hard surface geometry that has already been heavily optimized. It will be difficult to return it to an easily work-able state. The detail along the side may be too fine to survive either a Dynamesh or a ZRemesher process no matter what you do.
You can attempt to Dynamesh it at extremely high resolution. This produces high resolution geometry where the fine detail and edges are maintained by the virtue of the dense points on the surface. When you remove points, you will lose detail like fine edges.
Zremesher creates new low resolution geometry. Hard surface geometry loses definition when converted to low poly, because it loses the points on the surface that maintain the form. When you attempt to smooth the mesh by subdividing, the subdivision smoothing will further soften the form.
The only way to avoid this is to try and get ZRemesher to draw the edges exactly where they need to be in order to Crease the edges, which marks them to stay hard-edged during the subdivision process.
Normally you would attempt to do this by making sure that each edge that needs to stay hard edged is bordered by different polygroups, then use the ZRemesher Keep Groups option.
However, Im fairly skeptical you will be able to remesh this geometry in any way that maintains the delicate detail you have there. You have a number of very finely inset panels with a recess that is too shallow to be easily picked up by Zremesher. The fine-venting on the side of the model is very likely to be beyond the reach of any process in the program.
This mesh either needs to come out of your external app in a less optimized, more evenly distributed quad topology, or it needs to come out in a less finely detailed form. The fine inset detail you have there is the last thing you should be doing with the mesh. It should be the final stage of your process.
Good luck!
