V4.4 `CSGPolygon3D` on path mode generating distorted faces or skipping faces

[lucasthomaz97]

Tested versions

• reproduceable in godot 4.4 stable

I migrated my project from 4.3 to 4.4 today and in my project i use a lot of csg polygons on path mode.

System information

Godot v4.4.stable - Windows 10 (build 19045) - Multi-window, 1 monitor - OpenGL 3 (Compatibility) - AMD Radeon(TM) Vega 8 Graphics (Advanced Micro Devices, Inc.; 27.20.11030.11001) - AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx (8 threads)

Issue description

The faces are getting distorted in some cases as this print:

when i create a plane, it just skips some faces

Steps to reproduce

BetterCSGPolygonToPath3D.zip

1. Add a path3d node to a new scene
2. Add this script to the CSG Polygon 3d node, i use it to generate the polygon.
3. Relate the CSG Polygon3d to the path node
4. Draw some curves and the issue shoud appear

Reverting pr #94321 seems to fix the issue. CC @fire

In a different comment the creator of manifold is working in a patch to avoid decimation unless necessary.

Hello! I'm curious if the 4.5 milestone is accurate and we shouldn't expect this pr until then? I just upgraded to 4.4 yesterday and my csgpolygon3d generation along a curve has distorted/skipped faces and while researching a fix, found this pr.

I'm waiting for #104048 's manifold library update. Like waiting for the manifold library to make a release.

Subscribe to elalish/manifold#1185 for updates.
