In a "Geometry Nodes" I use the "Proximity" node to set a different material if the distance between a cube and each face is less than a specific value.

It works fine, but now I would like the faces that have had their material changed to not change again when the cube distance is greater than the specific value.

Any ideas?

Thanks for your time and help!

    $\begingroup$ The easy way would be to use dynamic paint. There is probably some other way to do it now with the simulation nodes that I haven't tried yet $\endgroup$

  1. double your plane, rename it to "save", give it this GN modifier:

  1. in your plane, make a nodegroup of your node tree, then change your node tree to this:

of course you have to change the behaviour of your cube, because i don't think you want that behaviour - but this is another question ;)

Hope that helps.

  • $\begingroup$ you can do it more "elegant" with the new simulation nodes - but i am not sure whether the new GN version would be ok for you... $\endgroup$

  • $\begingroup$ I have the version 3.2.0. You would change to the new version 3.4.1? $\endgroup$

  • $\begingroup$ it depends...as usual ;) if you are working with Blender "just for fun" and not for customers - i would recommend using the newest so you learn the new things very early ;) and you can use the newest crazy features at first! ;) i am working with 3.6.... ;) $\endgroup$
