When you start modeling in Blender, you get involved in a prolific-creative process which is excellent! But sometimes, it can be a little hard to observe all the elements you transform due to the grayish cover of the objects you are modeling. In the orthographic view, you may not even be able to identify your latest updates, and perhaps when you put a different perspective, it is a bit difficult to see the edges of your figures. Believe us. That can be such a headache! Why should everything be so laborious? Don’t worry! Here is how to activate the Cavity Option.
Before we begin, it should be made clear this can help while you are still transforming objects, and you need to point out some details to continue modifying in the Solid Mode.
So, let’s start by selecting the objects you want to visualize. Then, go to the panel at the top right, where you will find the different display modes, and at the end of them, you will see a dropdown arrow.
Once you click on the dropdown arrow, you will find a small panel. Almost at the end, you will see some alternatives to check, so go to the Cavity Option and click on it. Then you can set the tool’s specifications until you feel comfortable with the result.
Something great about the Cavity Option is that you don't need to increase the values or do a complex setting to observe how this tool works. Just with the first click, you’ll immediately see the result. The first thing you will notice is the emergence of two types of lines. The black line shows the edge at the bottom, and the white line shows the frontest edges and external parts of your model, generating a sense of depth that can help you see better what you are editing.
Now nothing can stop you. You can continue transforming all the objects you want to visualize more easily. Did you expect it to be this easy?
