Way to make a gradient for emission strength based on elevation So through watching tutorials on YouTube I've learned how to change the colour of an object based on its Z orientation using a ColorRamp while only using one material. However, I'd like to also know if there's a way to make objects which are higher up have a lower emission strength without making loads of different materials, as I would have a lot of objects to work through.
I'm not sure which tutorial you followed, but you probably have something like this in your node setup. Just add an invert node between the colorramp and separate XYZ node.
