Bad view in Firefox and ok in IE

Thank you for contributing to Armory!

Description In image we se some defects on Firefox 100.0

To Reproduce Run the example files

Expected behavior Good view without defects in Firefox

Hi, I guess you're using the third person template file?

For me it looks totally fine on Firefox:

Please try if the error goes away if you use Blender 2.93 LTS (Armory only supports that version, support for the 3.3 LTS version will follow if Blender 3.3 is released). Does the issue still happen if you set Armory Render Path > Post Process > SSGI to No AO?

[QuantumCoderQC]

I can confirm this issue on FireFox and Chrome. Both in the online example browser and when run from Blender by targeting browser. It however does not occur when targeting Krom.

All tests below are done in Blender 2.93 LTS

Browser:

Krom:

Here's the result with SSGI set to no

Browser:

Krom:

So, yes, disabling SSGI seems to solve the issue. But it still is not a permanent fix in my opinion.

This might be a quirk of the GPU?

This might be a quirk of the GPU?

Yes, maybe. I still can't reproduce it on my GTX 750Ti (so Nvidia as well) even after reinstalling the latest drivers. Maybe it's an architecture specific thing?

I can partially reproduce the as well, I suspect it's modern day GPU driver issue. Perhaps related to a similar bug me and several others had with PlayCanvas and shadows.

On a side note, aren't these shadows screen-spaced? They're suppose to have poorer quality for optimal performance...

Specs: OS: Windows 11 Home GPU: NVIDIA GeForce RTX 3050 Ti Laptop GPU CPU: 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz 2.30 GHz (8 cores)

Can you please try to replace the following line in <armsdk>/armory/blender/arm/write_data.py

https://github.com/armory3d/armory/blob/7203c3296021e0283a039068edea0fd117d033dd/blender/arm/write_data.py#L516

with

    <meta charset="utf-8"/><script src="https://greggman.github.io/webgl-lint/webgl-lint.js" data-gman-debug-helper='{"throwOnError": false}' crossorigin></script>""")

to use this debug library, then restart Blender, build and run the game again and then paste the output of the browser's console? It should look something like this, maybe we have different errors/warnings that can give a clue about what's wrong with the ambient occlusion:

Note that not every warning/error must be severe, but it can be a hint.

• not sure I made this in good, soo.. you can try put right example on remote server and I can run this html to see logs

Thanks! Looks correct to me. Unfortunately it doesn't look different to the errors I get, so the issue is probably caused by something not related to how the AO shader is invoked or what data is sent to it. Maybe it's indeed a driver issue?

[ManPython]

Maybe it's indeed a driver issue?

Take attention that on IE is ok just FF. I hear that on FF some webgl aps working slowly and with worst performance. And maybe it can be this issue more like driver https://www.reddit.com/r/firefox/comments/eh6d64/webgl_gets_worse_performance_in_firefox_compared/

[ManPython]

Problem is still not solved? I'm testing armory_templates-22.06 on UPBGEv0.2.5b2.79Windows64 with ArmorySDK2310
