How to get a perfect vertex normal for cylinder in maya?

dannnnT · Apr 2020

Hello guys,
I am trying to find a script which can give a perfect normal for cylinder in maya, any suggestions on what are you guys using now?

I have tried some smart scripts, but all can not give a good result as the pic below:

The vertex normal on the around side is not able to perpendicular the face perfect, but on the top and bottom looks nice.
Is there a way to make the cylinder get a perfect normal in Maya with some scripts？ Seems some use face weighted normal, other's use average normal algorithm?

Try this script by Pontus Karlsson (www.pomperi.com) since 2013. Works perfectly for me.

Hi pasha_sevez, thanks for your suggestion. I have tried the script you posted here, it can give a perfect normal on the around side, but for the top and bottom, it will exist some angles with the faces, i mean not perpendicular.Looks a opposite situation with my screenshot.

Is that because i lost something?

How i used the script is：

1.create a cylinder and make a bevel, then got to mesh display and select soften edge

2.select all faces, run the script
