I’ve followed this guide to ensure that my VFX graph is rendered but nothing is displayed on my Oculus Quest device (no errors, no effects):
If I run this on desktop (Oculus Rift), it works just fine.
But it doesn’t work at all on my Oculus Quest device.
I’m using:
What else can I check to make it work?
Hi @masta-yoda ,
I’m afraid there are some known driver issues with Android devices, you can find out more in this thread or check out this issue. I believe these issues are resolved in Android 9.
The VFX Graph is only out of preview for HDRP, so the development focus has been mainly there. We have started looking now into the full URP integration and mobile device support for compute-capable devices. You can track the status and upvote the features on our product roadmap.
@VladVNeykov , I also tried to build a VFX visual effect and output to oculus quest 2.
my Unity version is 2019.4.12f.
not using Vulkan
API level 23
URP.
I can get the effect I want in my macbook pro (picture 1) , but end up fail on the oculus (picture 2)
do you think that’s due to the same issue?
Hi @fadedmemory_unity , it definitely looks like it can be the same issue!
I have the same issue 
I just follow the video tutorial topic starter has mentioned. Everything is work for me.
6. (2:03 in video) I have added Hidden/VideoDecodeAndroid shader in Graphics tab.
7. (2:25) II have added Ultra quality level, and set its values accordingly the values in tutorial video.
After all these steps my builds shows correct VFX:
Tried upgrading to 2021.2b but it now has problems with hashes , says twice
syntax error: unexpected token '#' at kernel CSMain
in all of the compute shader sub files inside the asset
thinking maybe i should try create a new graph from scratch and copy the nodes over since now the visual effect graph package version is 12.1.0 ( also urp and shader graph have similar version numbering )
maybe its OpenGLES3 ?
when i try to show compiled code that’s all i see :
**** Platform OpenGL ES 3:
Compiled code for kernel CSMain
keywords: <none>
Failed to compile compute shader.
Also just tried creating a " new_vfx " graph and it looks like im getting the same errors
Shader error in '[vfx_particles] [System] Update Particle': syntax error: unexpected token '#' at kernel CSMain at C:/Projects/DreamMeditationVR/Library/PackageCache/com.unity.visualeffectgraph@12.1.0/Shaders/VFXCommon.hlsl(136) (on gles3)
[Worker3] Attempting to get Camera relative temporary RenderTexture (width || height <= 0) via a CommandBuffer in a Sriptable Render Pipeline.
[Worker3] Trying to get RenderBuffer with invalid antiAliasing (must be at least 1)
...
so basically adding the vfx to the scene it will not render the particles, however oddly enough the inspector does
Switched to vulkan instead of OpenGL , no more errors , everything seems ok now
Seems like i missed that one , this what was preventing it from rendering in scene.
just build the apk and tried on the quest2 , seems to work just fine )))
Hi VVad (and anyone seeing these issues); please try upgrading to latest 2021.2 beta.
A number of fixes addressing the stretched particles as well as some OpenGL-specific issues were fixed in the VFX package which ships in 2021.2.0b14.
If you still experience issues after, there might be some GPU-specific issues running gles.3.1 in which case switching to vulkan is recommended (as you saw yourself 
)
