This free 3Ds Max script will randomize the wire color of selected objects. In this script, I have opted to use softer pastel colors, akin to Blender colors.
The script can prove useful when you've imported a CAD model where all wireframes are sometimes black or when detached geometry has numerous parts with the same wire color, making it challenging to distinguish between the detached parts.
Installation: Drag and drop onto the 3dsmax viewport, then navigate to Customize > Customize User Interface > Menus (you can place it anywhere you want, but the "main menu - tools" is an ideal location for this script). In the Category section, under "Shiva Tools", you will find "Random Wire Color". Drag it to any Tools submenu or wherever you prefer.
