polygon mesh 'heal'

[Eugen]

Hi,
what's a good way to more or less automatically heal a mesh that is split up in plenty of islands, with randomly flipped normals?
Because that's what I get after importing some architectural assets (fittings etc.) via OBJ or FBX.
No worries about UVs in this case, just need a simple but clean mesh.
Cheers!
Eugen

Found this compound by Christian Gotzinger:

but it seemingly does not work across multiple poly islands.

Any other ideas?

Hi Eugen,

Look at this thread on the Softimage Mailing List for options/ideas.

The script from Matt Lind "ML Unify Normals" is also available on "The Area"

https://area.autodesk.com/downloads/scr ... fy_normals

I have downloaded it for you.

AUTHOR: MATT LIND

FINDS ALL INVERTED POLYGONS ON SELECTED POLYGON MESHES, AND INVERTS THE NORMALS TO POINT OUTWARD (EG: REDRAWS POLYGON USING COUNTER-CLOCKWISE ORDERING OF VERTICES TO COMPLY WITH RIGHT HAND RULE).

SUPPORTS INPUT ARGUMENTS FOR USE IN SCRIPTING: XSICOLLECTION, COMMA DELIMITED STRING, OR ARRAY OF POLYGON MESHES TO BE PROCESSED. NON-POLYGON MESHES ARE FILTERED OUT BY THE COMMAND. * NOTE: THIS COMMAND DOES NOT CONSIDER USER NORMALS WRITTEN AS A SELF INSTALLING COMMAND USING JSCRIPT LANGUAGE.

USAGE:
1) SELECT POLYGON MESH(S).
2) MODEL > [MODIFY] POLY.MESH > ML UNIFY NORMALS

INSTALLATION:
1) DRAG AND DROP SCRIPT INTO THE PLUGINS FOLDER OF ANY WORKGROUP.
2) START XSI. IF XSI IS ALREADY RUNNING, YOU CAN REFRESH PLUGINS THROUGH THE PLUGIN MANAGER OR TYPE AND EXECUTE "UPDATEPLUGINS();" (JSCRIPT) IN SCRIPT EDITOR (NOTE: MAY HAVE TO MODIFY SYNTAX TO ACCOMODATE WHATEVER LANGUAGE YOU'RE USING).

That did the trick, thanks so much!!
Love this community...

Could fix some of the parts, but others were so garbled, not even black magic helped, had to rebuild them.
What's the thing about CAD data sometimes?? If you see DXF anywhere near, just run... (those downloads were DXF and FBX. Tried FBX).
