GLES 2 DoF near does not work on mobile (android tested)

[ClintochX]

Godot version

3.5.1

System information

Windows 10, Intel core i5 (2 cores @2.8Ghz), Intel HD Graphics 4000.

Issue description

In GLES 2, I created a simple scene with spheres on them, I added DoF near and increase the blur amount, it works fine when I run it in Editor and project but when exported to android, it doesn't show at all. Though the DoF far works fine only that the DoF near doesn't work at all.

Steps to reproduce

1. Switch to GLES 2
2. Add simple 3D Meshinstance node with a primitive mesh to the scene
3. Add a camera3d node
4. Add an environment node
5. Enable DoF near in the environment properties settings and adjust the amount
6. Save and export it to an android device
7. Run the Demo. And you'll notice that DoF near doesn't work.

Could you please upload an MRP to make this easier for contributors to troubleshoot?

An MRP is a project that is as small as can be while still reproducing the bug you are reporting. We include the MRP in the bug reporting template as including one greatly increases the chance that a contributor will be able to reproduce the bug you reported and be able to fix it.

Could be a duplicate of #15526

@Geometror I only changed milestone because Akien has suggested we go through and mark issue milestones relevant to 3.5 as 3.6 (or 3.x), then mark any PRs as cherry pick 3.5. 👍 🙂

@clayjohn This is the sample demo project file. Export it to an android device Download

I'm currently using Godot 3.5.1 and running on Redmi 9a (2GB RAM) for reference.

I wonder if this is a precision issue that can be resolved by enabling Enable High Float.android in the Project Settings, then exporting the project to Android again.

@Calinou I did enable that also, besides That option is only useful for shader calculations.

as a matter of fact, the DoF far works just fine in all scenarios, quality and settings but the DoF Near simply does not work at all.

besides That option is only useful for shader calculations.

Built-in rendering features still make use of shaders, even if you can't modify those without recompiling the engine 🙂
