How to paint weights on points to be used in Bifrost graph

Anonymous — Fri, 30 Aug 2019 17:24:20 GMT

Hi everybody,

I am new to Maya and wondering how to paint a weight per point to be used in a Bifrost graph?

I have seen that it is possible to paint weights for Maya's stock deformers, but I do not know where that data is stored. I do not know how to access it in the outliner or in the node editor. And I don't know how to create a weight map not associated to a deformer.

I know I could paint a color set and use that in Bifrost, but this seems like a workaround, I do not want to create rgba channels. What is the correct workflow to paint a custom weight map?

Thanks in advance! 🙂

You could create color set, paint the weight, and use that data to feed into your bifrost graph. Check 'My Oh Maya' video: https://www.youtube.com/watch?v=zYg0rNr44pA&app=desktop

You could also create custom attribute, make it paintable and play with that

Hi armanmusovic, thank you for your answer!

Yeah, the "color set" method is what I do right now, but it feels like a workaround to drag extra float channels when all I need is one.

Making an attribute paintable is really what I am looking for, thank you for suggesting that. I have googled that and found this : https://knowledge.autodesk.com/support/maya/learn-explore/caas/CloudHelp/cloudhelp/2015/ENU/Maya/files/GUID-FE4A41B8-BBBC-46A3-B334-9C1023452012-htm.html

Is this really the only way to make an attribute paintable? Through a scripting command?

Or is using a "color set" the genreally accepted method of doing this in Maya? (I am used to create a "weight map" property in softimage or a point attribute in Houdini)

Thanks in advance!
