Fix Meshes

Lots of users experience issues with their meshes. This script provides a convenient way to do all of the common mesh-fixing steps.

USAGE

• Select one or more geometry objects
• run script
• choose from any of the below buttons
• Reset Xform - Resets selected objects XForms
• Reset Normals - applies an edit normals modifier and resets all of the normals (so that they are again controlled by smoothing groups)
• Reset Object - creates a new box object and attaches the existing mesh to it, then deletes the temporary box.. This essentially wipes all object properties. material, wire colour and pivot are all retained.
• New Scene - exports the selected geometry, creates a new scene and imports it again. deletes the FBX file when done.

    
-- Mixescript snippet: Fix Objects
-- attempts to correct common problems with meshes

-- USAGE
-- select the bad meshes
-- run script
-- choose any of the buttons. I recommend working top to bottom
