Floating point division by zero at kernel Warnings are thrown when opening VFX Learning Sample Scenes
Steps to reproduce:
- Create a URP Project and Install the VFX Graph
- From the Package Managers VFX Graph Package page import the Learning Templates Sample
- Open Scene "URP_VFX_Learning_Templates"
- Zoom out in Scene View so all GameObjects are visible
Actual results: Warnings are thrown:
"Shader warning in '[MultiStripsSpawnRate] [Multi Trails] Initialize Particle Strip': floating point division by zero at kernel CSMain at MultiStripsSpawnRate.vfx(179) (on d3d11)"
"Shader warning in '[MultiStripSingleBurst] [Robot Arms] Initialize Particles': floating point division by zero at kernel CSMain at MultiStripSingleBurst.vfx(187) (on d3d11)"
"Shader warning in '[MultiStripsSpawnRate] [Multi Trails] Initialize Particle Strip': floating point division by zero at kernel CSMain at MultiStripsSpawnRate.vfx(178) (on d3d11)"
"Shader warning in '[MultiStripsSpawnRate] [Multi Trails] Initialize Particle Strip': floating point division by zero at kernel CSMain at MultiStripsSpawnRate.vfx(179) (on d3d11)"
Expected results: No Warnings are thrown in Learning Sample Templates
Reproducible with versions: 6000.0.33f1, 6000.1.0b1
Can’t test with versions: 2022.3.55f1 (No Samples)
Tested on (OS): Windows 11, MacOS 15.1
