Displacement - Sharp corners

[pBarrelas]

Hello guys, this is just a quick tip on how to apply displacement to objects with 90 degrees and sharp corners.

On image 1, we have a cube primitive to illustrate this example. After we apply a cellular map to the displacement channel, due to the normals direction the displacement "moves" the geometry and the corners get open - image 2.
The simplest way for us to get rid of this problem is to use smoothing at 100% (on the material properties) and increase the smoothing angle to a value higher than the angle the faces have between each other. So don't get in panic after the result you get in image 3.
The final step to take care of this is just to uncheck smoothing positions at the render settings and you have the problem resolved - image 4.

I hope you enjoyed this tip as much as me when i faced this problem!!

Thanks for the useful tip Paulo... I usually tried to solve this problem by beveling the edges... but this is really interesting... help to keep edges sharp

This has been bugging me for a while. I don't use displacement much, but when I did I had the problem. Thanks for the great info Paulo.
