Yet Another Vertex Normal Editor (Y.A.V.N.E.)

Yet Another Vertex Normal Editor (Y.A.V.N.E.) by fedackb

after a lot of search for a way for create a lowpoly model with nice smooth, i find this lovely addon for blender.
now i want to share it here for those who do not know anything about this.
and i suggest you to use it, very helpful for keep vertex low and have right smooth on beveled edges and flat faces.

This Blender addon provides a set of tools for editing vertex normals.
As seen in the following image, Y.A.V.N.E. can dramatically improve the visual quality of a mesh without altering geometry.

User Interface

Y.A.V.N.E. is available within the 3D View > Sidebar > Tools tab for any mesh object in Edit mode.

Vertex Normal Weight

Vertex weight types determine how each vertex normal is calculated as the weighted average of adjacent face normals.
Y.A.V.N.E. provides several weighting options:

• Uniform - Faces normals are averaged evenly.
• Corner Angle - Face normals are averaged according to the corner angle of a shared vertex in each face.
  This is the smooth shading approach used by Blender.
• Face Area - Face normals are averaged according to the area of each face.
• Combined - Face normals are averaged according to both corner angle and face area.
• Unweighted - Face normals are not averaged; vertex normals are static.
  "Set", "Merge", and "Transfer Shading" operators result in unweighted vertices.

Face Normal Influence

Face influence types determine which face normals are considered when calculating vertex normals.
In the case that a vertex is shared by faces of different types, only normals from the most influential faces contribute to the resulting vertex normal.

Faces have Medium influence by default.
A typical workflow involves assigning Weak influence to transitional portions of a mesh, such as bevels (I).
Alternatively, users can specify more influential areas by assigning Strong influence (II).
It is even possible to use all three face influence types in a single mesh (III).

Great! Super Blender add-on. I hope that you will regularly update this perfect add-on.
It would be nice to give a brief explanation of how to activate in Blender.
Thank you again for this addition.

Ah, someone else who has discovered the power of YAVNE. It is my second most-used Blender plugin, besides Viewport Rename (and, of course SCSBT). I would go crazy without it.

[AmirMahdavi]

@tobrago Thx for attention but in top of topic i said, I FIND this and i am NOT creator
Just want to introduce it.

For installation, Download file, extract it and put the yavne-xxx folder in addons folder of blender in
C:\Program Files\Blender Foundation\Blender 2.XX\2.XX\scripts\addons\
Or
C:\Users\AppData\Roaming\Blender\2.XX\scripts\addons\

And for usage, see the Face Normal Influence section of first post

i will create a video in this week for better understanding

@smarty yeah reallyyyyy powerful
I decrease a model with 240,000 vertex to only 40,000 with this beast of normal editor

[tobrago]

@ AmirMahdavi, yes I know, I apologize for writing errors.

Well, I copied the directory "yavne-2.79" in "C:\Program Files\Blender Foundation\Blender 2.79\scripts\addons\" and how to activate it in Blender to get the add-on, thank you. I can not find him "yavne-2.79" in "Blender User Preferences"?

[AmirMahdavi]

@tobrago no matter folder name
in this case you must search (Y.A.V.N.E)

[retoucher]

@tobrago:
You won't find it because it's not work with the latest version of 2.79

It would be here anyway: Edit Mode -> Shading/UVs

It would be here anyway: Edit Mode -> Shading/UVs

It's not even here where you wrote it. I'll wait until the correct version comes out. Although I don't think it will be soon.
The Blender version I use is 2.79b.

[AmirMahdavi]

i test it again with final version in steam and other 2.79b i installed before
and no any issues with addon

whats your problem?

[Braakie]

Thanks for the tip, seems to be a very useful addition to Blender, works perfectly with blender 2.79b.

Make sure you unpack the zip file and do not have a duplicate folder when you place the folder in Blender\2.79\scripts\addons\yavne-2.79
