[Sidefx-houdini-list] Paint in absolute mode

I've been hit by this before too, never really understood why we can't have an absolute mode, deltas seem procedural but I can't think of many situations where they will still work if the input changes. Fine for sculpting but painting colours is mostly best as absolute, rather perversely more so in a procedural setup.
I think I ended up doing the same thing as Francois.

Hi Francois,

I had a similar situation and ended up using separate attributes to paint on and combine the initial data and whatever the user paints, in a VOP SOP using add/mult/etc.The downside however is, the user will have to paint on a fresh 'canvas' and can't see what you prepared beforehand, since you can only display one attribute at a time in a Paint SOP (to my knowledge).

Hope this helps.
