I am trying to make a metalic paint and would like to inver the noise node so it is the spots that get highlighted, could another maths function do it?

Invert like this?

Yes now can this be connected to the noise node?

Sure. Just plug the noise node into Value_2. I only used the tile node as an example, so you could clearly see what the math node was doing.

You can use this trick to invert image maps, also. Or raytraced reflections. Or pretty much anything, for that matter.

Hi Irish,

Just an idea that you might like (since it doesn't involve numbers, just colours).

Instead of using the "Math Functions" node, you can use "Color Math".
Does much the same thing, but can sometimes be easier to visualise.

Inverting an image (Color Math; subtract image from white). See above...

Cheers
Diolma
(and happy Xmas)

And that can lead to other interesting possibilities... Subtracting from a Colour... (BTW: Just using Turbulence as an example - almost ANYTHING can be plugged into the Color Math node, same as the Math Node as Little Dragon explains. In fact almost anything can be plugged into any other node. There are very few restrictions..) Cheers, Diolma (and a Merry New Year)

wow thanks both of you I am starting to see potential for nodes I previously had nothing to do with!

Thanks for this one.  I asked all over and everyone said it couldnt be done.  I had the trouble of a backwards alpha map.  I just needed to flip it, and was told the only way was to take it into photoshop.  Will work on this tech tomorrow.
