Resampling a Surface object to a specific polycount? Can't calculate ratio

[kritskiy]

I think my issue comes from the fact that the value in the tree (that's also output by .getPolycount() is not the same as the initial value in the Resample dialog:

 

So when I run this I'm getting a wrong result.

active_element = coat.Scene.current()
vol = active_element.Volume()
active_polycount = vol.getPolycount()
   
target_polycount = 50000

resample_scale = math.sqrt(target_polycount / active_polycount)

# prints out current polycount: 176; resample_scale: 16.85499656158105, the resulting polycount is at 12k
print(f"current polycount: {active_polycount}; resample_scale: {resample_scale}")

def ui_command():
    coat.ui.setSliderValue("$ResampleParams::ResamplingScale", resample_scale)
    coat.ui.setEditBoxValue("$ResampleParams::RequiredPolycount", target_polycount) # this seems to be completely ignored
    coat.ui.cmd("$DialogButton#1")

coat.ui.cmd("$Resample", ui_command)

 

If I manually put 41 as active_polycount, the resampling is correct. So my question is, how do I get this "initial polycount" value, 41 ?

Or maybe how can I use $ResampleParams::RequiredPolycount instead of ResamplingScale ? Putting any value in it doesn't seem to change anything

Oh, this works. But this seems... weird and wrong?

def ui_command():
    initial_polygon = int(coat.ui.getEditBoxValue('$ResampleParams::RequiredPolycount'))        
    resample_scale = math.sqrt(target_polycount / initial_polygon)
      
    coat.ui.setSliderValue("$ResampleParams::ResamplingScale", resample_scale)
    coat.ui.cmd("$DialogButton#1")

coat.ui.cmd("$Resample", ui_command)

As I remember that issue was solved on version 27

I'm on 2024.27 though (forgot to mention, sorry)
