Joren Kandel’s criteria for a “perfect tip” is that it has to e easy to implement, and it can save you a lot of time. This tip will do both. When texturing in 3D, there will be multiple occasions where the same material will be used in multiple texture channels. If this is the case, wouldn’t it be great if you changed the parameters on one noise, and all the other noise textures on other channels would update? Linking texture slots would be great.
That is entirely possible. Joren shows how you can set one to be the driver, and the others to be driven, changing the driver attributes will automatically update the others. This is done by selecting an expression through a simple contextual menu.
Joren shows how linking texture slots works with procedural elements like noise, but also work with images and alpha channels as well. That should save a ton of time!
