Displacements are fantastic for adding details to your model, without actually modeling those details. The problem becomes that you can’t actually see what a displacement is doing int he viewport. Displacements by nature are rendered effects. It is possible to make a displacement visible, so that you can work with it better.
Just a little tip for if you need to use displacement.
Going back and forth between settings and tweaks and rendering can really eat up your time. This is why it could be really handy to make a displacement visible in the viewport. Here, The Pixel Lab’s Joren Kandel shows how you can make them visible in C4D without rendering.
This can be done by using the Displacer Deformer. Because the Displacer is a deformer, it can be easily viewed without rendering.
Comments, Davor Mihalji noted, If you want to take it a step further and use the displacement from the material settings, you can easily make that visible in your viewport without rendering, too. You can do this by placing it in the same “Displacer” deformer as a child of the object you are working on, and check “Emulation” under the “Object” tab from the settings.
