Hello, I am using unity 2021.1 and I tried making a VFX with it but I doesn't show up and I got this error with it.


Shader error in 'Hidden/VFX/Snow/System/Output Particle Quad': redefinition of 'PackHeightmap' at /Users/Admin/Documents/APP/Across/Library/PackageCache/com.unity.render-pipelines.core@11.0.0/ShaderLibrary/Common.hlsl(1198) (on d3d11)

hi, for me it was linked to that i used a HD RenderPipeline, I came back to the default RenderPipeline and it was fine for me
So i stop to use VFX effect that wont work on somes cases in HD RenderPipeline and i use Particle System with Default Pipeline

 

I am currently using built in pipeline.. as I got the error..

 

i had the same errie with this Render Piepline.

maybe can this help (follow the link inside)

Documentation say
https://docs.unity3d.com/2020.1/Documentation/Manual/com.unity.visualeffectgraph.html
The Visual Effect Graph is a node based visual effect editor. It allows you to author next generation visual effects that Unity simulates directly on the GPU. The Visual Effect Graph is production-ready for the High Definition Render Pipeline and runs on all platforms supported by it. Full support for the Universal Render Pipeline and compatible mobile devices is still in development.

So if you want VFX better way to use HDPipeline or use particle system for other Pipeline
good luck
