Cavity Shader: Edges and Contours

With Cavity you can easily render a screen-space cavity effect to highlight edges, cavities and corners. This is perfect to liven up low poly models and make them pop.

✅ Easy to use.

Just add a single renderer feature and you're done! 

✅ Masking and fading.

The effect works as a screen-space effect by default, but you can exclude/include objects as you wish so not everything needs to be affected.

✅ Fading.

You can fade the effect by height/distance as to not clutter the scene visually.

✅ Optimized.

The shaders were handwritten from scratch for maximum performance. In addition, Render Graph and the SRP batcher are leveraged.

✅ Configurable.

A lot of work has gone into making the asset as customizable as possible to suit your needs while not being overwhelming. Every option is clearly explained with a tooltip and with a custom editor UI everything is neatly organized.
