Paint node - invert

[McNistor]

I'm using the usual setup of attr-create with a paint node to drive something. I'd like to use the same paint values for something else, but inverted. I tried a few things, but something eludes me.

What's the most straightforward way of achieving this?

Thanks.

f@invert = (1 - f@value);

Knowing the invertion (1-something) is not the issue in my case, but knowing how to approach the problem I'm having from an workflow pov.

I've writen in an attribwragnle node f@new_attrib_name = 1 - f@attrib_name but nothing that I'm expecting is going on in my viewport.

I'll dig more into this, since it's the easiest thing I can do currently, explaining my particular case being a bit more cumbersome and sharing the whole scene is out of the question.

Your reply is appreciated - it confirms I'm doing at least something well.

If the problem is visualization, the Paint SOP has an internal visualizer that only applies when that SOP is displayed. If you want a persistent visualizer, you can use a Visualize SOP, or click on the attribute name in the Node Info window if you're on H17.

Pff... I'm glad my brain-fart didn't last longer - I was on the verge of painting textures.

I placed the wrangle before the paint node not realizing no modified att values have been stored prior to paint. Geo spreadsheet saved the day.

Yeah, no, I've screwed up - see above.

Again, thanks for the input - it stopped me from going down who knows what rabbit hole...
