Filling/replacing empty poly-panels Zmodeler

I don’t know how to word this, but when working in polyframe mode with zmodeler, I often find empty panels/space or error in geometry (most likely from me still learning how to use zmodeler effectively) where I would like to be able to fill them, or “copy/paste” new panels or spaces in. I know how to use bridge, close, close holes, and what not to do what should work for these issues, but I find they don’t quite work as I am trying to explain. For example, if I find an empty space between the modified polyframes, how can I fill them exactly as the negative space is shown? Also how can I generate “panels” or geometry in these negative spaces where zmodeler won’t respond. Here is one example in the screen shot below, as you can see the negative square spaces are what I am hoping to replace or generate, square by square or section by section.

Often using beveling, or qmesh combined with other modifiers causes receding in the polyframe creating negative space or “empty artifacts”.

Hope this is somewhat coherent, I have been scouring the web for an answer so I come here.

Not sure I really understand your question but perhaps try using the Zmodeler Extrude action with smart snapping to easily extend polygons and fill spaces or grow a whole row further. Search Michael Pavlovich Youtube for his videos on the Extrude functionality that was added a few years back to assist with topology definition, for example 034 ZBrush 2021 ZModeler Edge Extrude New Options - YouTube

Good Luck

Hello @ndsugi ,

I’m also not sure that I understand what you’re asking, but I do see some problems in the screenshot you posted. Polygons for which the polyframe does not accurately show the edges for usually indicate some sort of local issue with the geometry in that area. Often this means that the geometry is not correctly welded there:

Remember in ZBrush that ngons (polygons greater than 4 points) cannot exist at any time. Every operation must result in either a tri or a quad. What can happen is that there may be extra points involved in the operation that are preventing you from forming a properly welded polygon.

Please see the following example in which I have targeted one edge to target another edge, but it crosses another point on one side, involving 5 total points in the operation. This will prevent a polygon from being properly formed in that area:

A quad consisting of 4 points is formed between the two edges, but is not welded on the side of the 5th point. In cases like this you may need to first extend the geometry in another direction first so that you can cleanly form 4 point polygons, or you could extend the whole row at once like @tobor8man suggested.

It is also possible that there may be points that are closer together than can be easily seen with the naked eye. It can help to view your low poly model with Dynamic Subdivision mode on. This will smooth the mesh and may move any such points far enough apart so that they can be seen. Points like this can interfere with accurate targeting, and may prevent some operations from succeeding.

Good luck!
