Issue ID




Editor crashes on VFXSystem::UploadUniforms or throws errors when entering play mode with VFX Graph

Package: Visual Effect Graph


Reproduction steps:
1. Open the attached "case_1308481-Crash" project
2. Open scene "PhidgetsVFXTest" and enter the play mode
3. Observe the console

Expected result: No errors are shown in the console
Actual result: Console is spammed with errors or Editor crashes

Reproducible with:
(7.5.3 Crash) 2019.4.20f1, 2020.1.0a14,
(8.3.0 Errors) 2020.1.14f1, 2020.1.17f1, 2020.2.0b5
(10.1.0 - 12.0.0 Errors) 2020.2.0b8, 2020.2.4f1, 2021.1.0b6, 2021.2.0a4

Not reproducible with:
(7.5.3 - 8.2.0) 2020.1.0a15, 2020.1.13f1
(9.0.0-preview.13 - 10.0.0-preview.27) 2020.2.0b6, 2020.2.0b7

Can't test: (4.10.0-preview) 2018.4.31f1 (compiler errors)

The crash has no connection to the package version, only to the Editor. It no longer reproduces from 2020.1.0a15
It crashes in 2020.1.0a14 with all available Visual Effect Graph versions, while doesn't crash with the same versions in 2020.1.0a15

Deleting VFX Graph from the project solves both issues

[Test] [System (1)] Initialize Particle.compute: Kernel at index (0) is invalid

Shader error in '[Test] [System (1)] Update Particle': undeclared identifier 'GetWorldToObjectMatrix' at kernel CSMain at /Users/USERNAME/Downloads/case_1308481-PhidgetsSocial/Library/PackageCache/com.unity.visualeffectgraph@12.0.0/Shaders/VFXCommon.hlsl(87) (on metal)

  1. Resolution Note:

    The crash itself has been indirectly fixed by other change in 2020.1.0a15, especially the compilation on import behavior.
    The error has been fixed with this change :

    Also, this change prevent the double definition of PackHeightmap.

    However, the built-in renderer isn't officially supported by the Visual Effect Graph. This package requires URP or HDRP.
