Hi all,
I'm new to Houdini(outside lighting) and starting a grooming project for a stuffed animal.
Luckily there is a lot of tutorial material online!
But I'm running into a creative issue when trying to replicate the 'seams' of the toy.
Rather than painting them by hand, I'd love to use my 'group' which contains the seams.
And subtract the group selection from whatever has been painted.
I imagine this must be possible in an attribute wrangle or perhaps a node option I do not know.
As I'm new, I'd also take any recommendation on foundamental tutorials.
Cheers,
Max
Beginner: Set painted attribute to 0 based on group.

Hi all,
For now I've found the following solution.
Paint the 'soft mask' for furLift,
Paint the seams as it's own attribute.
Wrangle a new attribute that multiplies the seam attribute with the soft painted mask.
If anyone still knows how to convert a 'group' to an attribute that'd still be much appreciated.

Hello Max,
You could use an Attribute Adjust Float [www.sidefx.com] node or an Attribute Create [www.sidefx.com] node here, by limiting the node's operation to the seams group only.
This could be done on the 'soft mask' or 'painted attribute' directly rather than creating a second attribute.
If you need to have a second attribute, you could also use an Attribute Combine [www.sidefx.com] node rather than writing code in a Wrangle, as it has many usefull features for combining attributes, such as blending and clamping.
Here's a hip file with simple examples.
