Hair and Guide Viewport Display
Viewport Hair Display
Hair is displayed inside 3ds Max viewports using either shaded polygon lines or a special preview mesh.
Nitrous/Polygon Hair Display (3ds Max 2015 and Above)
Starting with 3ds Max 2015 a new way of displaying hair was introduced into Ornatrix- using special dynamically generated polygons instead of poly-lines. This allows for more information to be previewed by the hair such as its thickness and texturing. It also allows the hair to participate with shadows, anti-aliasing, and other new viewport enchancements in 3ds Max 2015 and above.
If displayed hair has less than 10,000 vertices the strands will always face the view in which they are displayed. However, this functionality is automatically disabled if the hair mesh has over 10,000 vertices to preserve viewport refresh speed.
It is possible to revert back to displaying hair as poly-lines, as it is displayed in 3ds Max 2014 and below. To do this open the [[Settings_Dialog:Ornatrix Settings]] dialog.
It has a "Polygon viewport hair" checkbox. Uncheck this option and press "OK". The hair should be reverted to poly-line display during the next viewport refresh. To go back to displaying polygon hair open this dialog again, check the "Polygon viewport hair" option, and press "OK". This setting is global for all of Max and will be remembered when you close and re-open 3ds Max.
Use an option in the Settings dialog to turn polygon hair viewport display on or off.
MaxScript access
Use these MaxScript functions to control how hair is displayed in the viewport:
-- Determines whether render version of the hair is displayed inside the viewport. When true the viewports will display final render hair instead of sparse preview version
OxSetDisplayRenderHairInViewports [bool]value [bool]sendNotifications
-- Turn on or off the Nitrous polygon hair display in viewport. When off, legacy polyline hair display will be used. This doesn't affect guide display.
