BNormal is the ultimate Plugin for your Face Weighted Vertex Normals in Maya

All pros :

  • Best Results on the Market
  • Automatic : No Manual tweaks required.
  • Performances: get results and speed, thanks to the Maya API
  • Works on every Meshes, picky cases, no racism: That point is the most important, and the other approaches didn't fully make it. (AKA cylinders..etc.)

'''Name : bnormal


Author: Baidhir Hidair "WaYWO"

Last Update : 3-25-2017 //based on mediochrea 's feedback on polycount


-BNormal has now two algortihms

-Algorithm 1 is the best one

-Use Algorithm 2 when results are bad. On cylinders Algorithm 2 is the best one

-command "bnormal" should be replace by (see below)

: bnormal -v 1 : (to use first algorithm)


: bnormal -v 2 : (to use second algorithm)

-as usual , reminder : smooth the edges of your mesh before applying bnormal , else, output is false

How To Use(

-Put BNormal.exe file under C:\Program Files\Autodesk\MayaVersion\

-run BNormal.exe and follow the instructions (AntiViruses Can be a-hole sometimes, I deactivated mine.)

-Go to Maya in Windows>Settings/Preferences>Plug-in Manager

-you should see '', check Load and AutoLoad

-You can now use the command :

bnormal -v 1 //(to use first algorithm)


bnormal -v 2 //(to use second algorithm)

//you can bind it to hotkey or shelf button)

-Select an Object OR Objects' and run the command, shelfButton, hotkey

-*Note 1( hard edges are now averaged.

If the meshes are not suited for FWVN

Workflow you can expect unwanted result.)

-*Note 2(If your normals are locked, colored yellow, if you

did apply bnormal one time, consider to unlock your normals

: go under mesh display>unlock normals>. Not doing so will false output)
