Maya: Adding second color per vertex

Hi all,

The artists at work wish to be able to modify their prelit scenes by tweaking vertex colors. However, if they move a light or re-light the scene for whatever reason, they would like the color tweaks to remain intact.

To do this, I'd like to be able to store a second color per vertex (or even a "tweak" delta value). Although I can use the Maya UI to add a vector attribute per vertex, and can do a similar thing through script, I'd ideally like to do this in a plugin. I also need some way of altering the rendered vertex color based on this extra tweak color.

Well, I hope that makes sense to someone, and thanks for any ideas you can chuck this way.

cheers,
stoo

Look up blind data and dynamic attributes in the developer giude, and there's more than one source code example in the dev kit. Basically the plug-in version of what you can do with MEL AFAIK

Hi,

Thanks for the reply. I've had a look through the dynamic attribute and blind data documentation, and played around with the blind*DataCmd examples. I can happily add a new attribute per node, but am having trouble actually adding the data per vertex. Is there something obvious I'm missing (normally there is)?

Thanks,
stoo

Well for per-vertex stuff I guess you just add an array attribute with the same number of elements as vertices...
