Script name: Bake UV-Texture to Vertex Colors
Wiki page: http://wiki.blender.org/index.php?title=Extensions:2.6/Py/Scripts/UV/Bake_Texture_to_Vertex_Colors
Category: UV
SVN Download: https://svn.blender.org/svnroot/bf-extensions/trunk/py/scripts/addons/uv_bake_texture_to_vcols.py
Status: >Release

%%%Features:

Bakes colors from the active UV Texture from the UV/Image-editor onto the vertices' Vertex Colors based on the position of their UV-coordinates.

Setup:

After installing the add-on it should work automagically. ;)

Manual:

First, unwrap the model like you normally would.
Next, load in the image you wish to bake into the UV/Image-editor.
The color baked to each vertex depends on the position of their UV-coordinates; it takes the color from right underneath it.
In Vertex Paint Mode, open the Toolshelf and click 'Bake UV Texture to Vertex Colors' under 'Bake'.

Quick test set-up:

Enable the add-on
Delete the default cube
Add a plane
Enter Edit Mode
Hit 'U' > 'Unwrap'
Subdivide the plane a couple of times*
Enter Vertex Paint Mode
Hit 'T' to bring up the Toolshelf if it isn't already
Under 'Bake' click 'Bake UV Texture to Vertex Colors'

*The denser the plane/ mesh, the more detail you'll get. (For cool-looking testing purposes, I'd advise to go up to 7 subdivisions ;) )%%%

This task was automatically closed as archived as part of migration, because it was determined to be no longer active.

The authoritative list of addons is on the wiki, we no longer have a report for each addon to track bugs and updates. Bugs can be reported individually and assigned to the addon developers. See the #Addons project page for more information on the workflow.

%%%Uploaded V0.3.

New features:

X- and Y-axis Mirroring
Mapping Modes for vertices who's UV-coordinates were outside the image bounds (Clip, Repeat, Extend)
Blend Modes (Mix, Add, Subtract, Multiply, Screen, Overlay, Difference, Divide, Darken, Lighten, Hue, Saturation, Value, Color, Soft Light, Linear Light)%%%

%%%Awesome round of additions Patrick! Cant thank you enough for your work to not only revive this functionality in 2.5x, but surpass it in many ways, mirroring, blend modes, etc, WOW!!

Pardon my reiteration, but PLEASE COMMIT THIS TO TRUNK, in addons, addons contrib, extern, whichever. This is core functionality game developers need in Blender, and Patrick has done the hard work of bringing it back to 2.5x. It would be a loss to see such functionality not be maintained in SVN.%%%

%%%Hi,
Due to changes to the api including the merging of bmesh, several addons are outdated.
Please, if you are the author of an addon check your script with blender revision 44256 or newer.
That is builds made After blender 2.62 official release.
I would ask that updates be made to your addon before the Blender 2.63 release.
6-8 weeks away.
This allows time for the api to become more exposed & bmesh to stablize furthur.
If you need help, drop into irc freenode #blenderpython or #blendercoders & feel welcome to ask questions.
At the time of 2.63 release, scripts that are not repaired or in active developement will have their tracker page marked "Closed"
this will not affect your links to the tracker, similar to closing scripts in 2.49b, the page will be still availible & can be re-opened.

Thanks for your understanding & patience during these Exciting Times.
Brendon.%%%

%%%hi,
Currently I'm still unsure of the working state of this addon.
The addon appears broken to me, marking as broken.
Please let me know if you have the intention of updating.
Thanks for your addon & interest in Blender.

%%%I rewrote bmesh related parts, it now uses loops (please review, dunno if my code is save, i assumed that mesh loop = uv loop = vcol loop)

replaced "for p in pixels: uv_pixels.append(p)" by pixels- [x] for even faster execution

tested some simple cases and seems to work again%%%

%%%Thank you for this script! Just what I needed. Very, very useful for creation of baked vertex lightning from lightmap texture.
Please make this to be included with standard scripts in blender.

...
Also this is a great script example how to work with vcolors/uv in blender. I actually need to write modification which writes values from uv channel in vcolor :). Don't ask me why - the game engine does not support more than 2 uvs, so I intend to export fbx with vcolor values r, g set to values of uv coords read from selected (third) uv layer, and use it later in game shader. %%%

%%%I just moved the script from contrib to trunk, so it will be included in next blender release (2.65).

A game engine supporting 2 UVs? Sounds strange, good look with your workaround!%%%

%%%Yes, it's Unity 3D. You can import only 2 uv channels per mesh... :).
Otherwise, great engine.%%%

Can you believe that Blender 2.8 doesn't support baking to vertex colors? Please we need this plugin working in 2.8. How much donation do I need to give lol, but srsly
