+|Shader Variant Limit| Enter a value to set the maximum number of shader variants. If your graph exceeds this maximum value, Unity throws the following error: _Validation: Graph is generating too many variants. Either delete Keywords, reduce Keyword variants or increase the Shader Variant Limit in Preferences > Shader Graph._ For more information about shader variants, see [Making multiple shader program variants](https://docs.unity3d.com/Manual/SL-MultipleProgramVariants.html). |
