Screened Poisson Surface Reconstruction filter is reporting a problem with the plugin in Meshlab 2020.07

[ortobajt]

Hello.
I have a problem with Meshlab 2020.07, which is installed on Windows 11.
When I run the following command in cmd:

.\meshlabserver.exe -i C:\Users\...\AppData\Local\Temp\in0.stl -o C:\Users\...\AppData\Local\Temp\out.stl -s C:\Users\...\AppData\Local\Temp\PoissonSurfaceReconstruction.mlx

I get the following message
Loading Plugins: Current Plugins Dir is: C:/Program Files/VCG/MeshLab/plugins "Cannot load library C:\\Program Files\\VCG\\MeshLab\\plugins\\filter_sketchfab.dll: Nie mo┐na odnalečŠ okreťlonego modu│u."

My PoissonSurfaceReconstruction.mlx script:

`<!DOCTYPE FilterScript>
<FilterScript>
 <filter name="Remove Duplicate Vertices"/>
 <xmlfilter name="Screened Poisson Surface Reconstruction">
  <xmlparam value="0" name="cgDepth"/>
  <xmlparam value="false" name="confidence"/>
  <xmlparam value="12" name="depth"/>
  <xmlparam value="5" name="fullDepth"/>
  <xmlparam value="8" name="iters"/>
  <xmlparam value="4" name="pointWeight"/>
  <xmlparam value="true" name="preClean"/>
  <xmlparam value="1.5" name="samplesPerNode"/>
  <xmlparam value="1.1" name="scale"/>
  <xmlparam value="false" name="visibleLayer"/>
 </xmlfilter>
 
</FilterScript>`

My out.stl is identical as in.stl

If I check plugin folder: C:/Program Files/VCG/MeshLab/plugins I see there is a filter_sketchfab.dll

If in filter scipt I add:
`

 <filter name="Change the current layer">
  <Param tooltip="The name of the current mesh" type="RichMesh" value="0" name="mesh" description="Mesh"/>
 </filter> 
 
 <filter name="Delete Current Mesh"/>

`

I get the following message

When I perform the steps contained in the filters manually in the MeshLab 2020.07 program, everything runs fine

I am sending the model in the attachment

See #911 - meshlabserver it is not supported anymore.
Moreover, the latest version of MeshLab is 2022.02.
Please check if the errors persist in the latest versions of MeshLab and PyMeshLab.

#911 is a completely different topic. In version 2020.07 meshlabserver is still installed and other filters are executed correctly. I'm asking about this particular case of a filter.

[alemuntoni]

#911 tells that meshlabserver is not supported anymore.
After 2020.07, 6 newer versions of MeshLab have been released. That means that bugs of 2020.07 may have been fixed in newer versions.
The issue you are reporting is about a tool that is not supported since two years. Bugs on that tool won't be fixed.
We can't and we won't support obsolete versions.
