Issues in Virtual Reality

[alexis-dupuis]

Hi ColinLeug-NiloCat,

First of all thank you kindly for providing a solution for decal projectors in URP, as it's quite an important feature yet missing in forward renderers.

I've been putting a lot of work on a decal system using your shader, until I realized it doesn't work in VR. I saw people reporting this issue on another decal projector shader (now depreciated), and the author apparently managed to make it usable in VR.

Would you know if it's feasible with your shader too?

Sorry I don’t have any VR experience before so I am not sure what to do, and I don’t have a VR device to validate the fix. I believe Lux URP essentials shader in the asset-store have the decal Shader that support VR

It actually works on VR (Oculus Quest 2, Unity 2020.1.12f1, URP with Depth Texture activated) out of the box, at least for me. The oculus texture plastered on the wall is the decal from Colin's shader.

edit: though I noticed that the decal is not rendered every other frame while moving, only for one eye (right in my case), no idea why.

Same problem for me, but it can be fixed in one step

Switch rendering mode to Multi Pass (Hope its not only oculus feature). But maybe you will have a decal moving delay in VR.

Interesting as I'm using Multi Pass too (on the Oculus you can't do Single Pass right now) and I still can only see the decal from a single eye:

In case anyone finds this in the future I found this option in Project Settings > Player > XR Settings > Stereo Rendering Mode

Still experiencing this issue in 2022, anyone know any alternative solutions? I just need a drop shadow for the character in my 3D platformer but in the VR build it only renders in 1 eye

I ended up going for the Lux URP Essentials asset for my project. The projectors worked out of the box in VR. It's a paid asset but it often goes on sale, and it has a lot of other interesting features for URP (especially the volumetric lights). Le mar. 16 août 2022 à 05:41, timothy92 ***@***.***> a écrit :

If you landed on this issue trying to have (default URP) decals working on Oculus Quest 2:

In URP Renderer settings I'm using:

• Depth texture mode "Force Prepass"

And in the Decal feature :

• Technique -> "Screen Space"

I hope this might help fixing the issue with this shader too.

(Testing it today with Unity 2021.3.12f it is working without any problem)
