Version 16 includes a new [block](https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@16.0/manual/Block-CustomHLSL.html) and [operator](https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@16.0/manual/Operator-CustomHLSL.html) that you can use to write [custom HLSL](
https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@latest/index.html?subfolder=/manual/CustomHLSL-Common.html) code directly in a VFX Graph. You can use this to script complex behavior in a single node. You can embedd custom HLSL code in the node or load it from an external file to reuse the code.    

### Templates window 
![](Images/WhatsNew_16_TemplateWindow.gif)    
VFX Graph 16 adds a [template window](https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@16.0/manual/Templates-window.html) to add a VFX templates into an existing VFX Graph.

Version 16 makes the smoke lighting model compatible with URP [Lit Outputs](https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@16.0/manual/Context-OutputLitSettings.html) and [Shader Graph](https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@16.0/manual/sg-working-with.html). This means that you can use lightmaps exported from third-party software to create advanced custom shaders to light a smoke texture in URP and HDRP.
