WorldEnvironment Auto Exposure only works if framebuffer allocation is set to 3D, not 3D Without Effects

[LoserFox]

Godot version

v3.4.stable.official.206ba70f4

System information

Android, huawei mate10 ,GLES3

Issue description

When I export a game that includes auto exposure post-processing to the android platform, the game screen will flicker. I think it is caused by auto exposure not supporting the android platform. I am using GLES3

Steps to reproduce

Use gles3 and auto exposure in any project to reproduce the problem

Minimal reproduction project

No response

I think you have to set rendering/quality/intended_usage/framebuffer_allocation.mobile to 3D in Project Settings first, it could resolve the flickering.

Although the flickering will possibly be gone, the auto exposure still won't work as expected I think. Could you try if #55983 works for you? You can try the export template in my own build in case it's not ready here: https://github.com/timothyqiu/godot/actions/runs/1586478548

The problem was discussed in private with "timothyqiu". The problem is that the default value of "framebuffer_allocation.mobile" is 3D Without Effects. This option does not support auto exposure post-processing. Replace it with 3D to solve the problem.

Reopening, as we need to amend the documentation to mention this.

Does this mean the following line in the class reference is incorrect?

godot/doc/classes/Environment.xml

Line 12 in 62b181a

These effects will only apply when the [Viewport]'s intended usage is "3D" or "3D Without Effects". This can be configured for the root Viewport with [member ProjectSettings.rendering/quality/intended_usage/framebuffer_allocation], or for specific Viewports via the [member Viewport.usage] property.

Could someone test all 4 of those effects with the 3D Without Effects framebuffer allocation (preferably on mobile)?

i will try it

After my test, only ss_reflections and ssao are invalid under 3D Without Effects on PC. I guess it’s the same on Android
