[VFX] Too many GPU Event leads to compilation error

-

Mar 22, 2021

After link of 6 gpu event to the same system observe the error
`syntax error: unexpected token 'if' at kernel CSMain`

Resolution Note (fix version N/A (awaiting for merge)):

Thanks for this report, the fix is pretty straightforward and related to this line of code : https://github.com/Unity-Technologies/Graphics/blob/master/com.unity.visualeffectgraph/Editor/Compiler/VFXCodeGenerator.cs#L144
However, 6 output for gpuevent are only possible on DX11 if the sorting is disabled or there isn't any particle lifetime, otherwise, you will get this error :
```Shader uses 9 UAVs (0 textures and 9 buffers), which is more than the 8 maximum currently supported on D3D11.0.This is OK if you are only targeting D3D11.1 platforms at kernel CSMain (on d3d11)```
