Do you use Managed Stripping?
The code relies on reflection during the initialization step to create an instance of each effect renderer in the list.
There are no other reference to the effect renderers in the code that would protect them from being stripped out.

So if you have managed stripping enabled, could you either:

• Disable it and try?
• Use the [Preserve] attribute on the effect renderers that you want to keep.

Could you try and see if this works?

Hi,

Thanks for the quick answer! Managed stripping has been disabled all the time. Should I still try the Preserve attribute?
If so, where exactly should I apply it?

Could the depencies of the package(.json) affect this?

[MeatG]

And what would be the difference between development build and normal build in this regard?

[yahiaetman]

I think it is worth trying. I am currently trying it on Unity 2020.3.4 on my machine.
I believe Unity builds the project in debug mode for the development build.

FYI, I tried both 2020.3.4 and 2020.3.5 - both have the same problem

Ok, the build finally finished.

I tried it without adding the [Preserve] attribute and it still worked fine for me.

I built it on Windows 10 for Window x86_64.
My Player Settings:

• Scripting Backend: IL2CPP.
• Api Compatibility Level: .Net 4.x
• C++ Compiler Configuration: Release.
• Use Incremental GC: No. (Edit: I don't think that this would matter)
• Managed stripping level: Low.

My Build Settings:

• Development Build: No.

Is your settings different? If yes, what is the difference?

[MeatG]

-I made a new project: Works
-Tried your settings in my project: Not working
-Made a completely new scene to my project with only one effect active: Not working

So there is something strange going on on my end... I have been chasing this bug in my code and settings for quite a long time before posting here. No idea what to do next :D

[yahiaetman]

Is it possible for you to send me the new project to try it on my machine?

[MeatG]

Got it!!

I have a big project with many years of development so it is not always easy to find problems - BUT I finally did find it!
It was a code obfuscator asset I was using.

Thank you so much for your help, anyways. Give me your PayPal -address so I can buy you a beer. :)

In the obfuscator, there was an option set to NOT obfuscate development version so that was the 'strange' thing
