Why is my projection messed up and green in my Android VR build but not in my game view?

Question

Hi, I am new to unity using 2019.3.7f1 with the "Projector Simulator" asset pack installed.

I am creating an Android game/tour application for an Oculus Go and trying to get these projectors to work. At the moment my problem is very hard to correct as it only appears when I have finished building and adding it to my Oculus Go.

I am using projectors which both show up perfectly running in my scene & game window however are pure green in the finished build. I also find that sometimes they only appear at certain angles which is even more confusing. For example, if i have my character perpendicular to the projection and looking straight then the projection shows up but if I look directly at it, it disappears again.

Any help would be greatly appreciated!!!

How it supposed to look, Running correctly in Unity

In Oculus, green projection other is just there playing but only available at certain angles)

Hi Ethan, Projector Simulator dev here.

It sounds like a pixel light count problem. The documentation regarding Oculus Go and Unity seems to say to avoid using more than one pixel light... I am not sure if this is just a recommendation for performance or if they cap it on the device regardless of what settings you use.

The Go could be using a different quality level than the scene view - did you increase the pixel light count on all quality levels?

You could also try setting Render Mode of the 3 spotlights under each projector to "Important".

The only other thing I can think of is switching from Forward rendering to Deferred, but the documentation advises against this for performance reasons. Might be worth a try if all else fails. Sorry, I don't have a Go to test with myself.

There is a forum thread for Projector Simulator which is a more appropriate place for specific asset-related issues (as most users here won't be familiar with Projector Simulator). I know I need to make this easier to find. Please post your results here once you have tried the above:
