Keywords

Advanced Dissolve is not just a one shader effect, it is a collection of various multiple effects that can be turned on/off any time, mixed together or used separately. Each of those effects is controlled using its own individual shader keyword.

All Advanced Dissolve keywords in material editor have background:

Advanced Dissolve shader has 9 groups of effects controlled by 39 keywords:

In Unity 2019.4 and later versions all keywords are local and they do not contribute towards Unity’s global keyword count limit (256).

Kewords in materials can be enabled/disabled using Unity's Material.EnableKeyword and Material.DisableKeyword methods, or using Advanced Dissolve controller script explained in the Run-time API chapter.

SRP Batcher compatible shaders are keywords free. All used keywords are baked inside shader and unused ones are removed.
