Non consistent behavior of PBR materials

[paleRider]

Dear people of this awesome forum:

Here I am again, looking for some help.

My sw development (of course with BJS) uses PBR materials (we are the greatest fans) .

The case is that this is a cross-browser multi-platform project. My scene looks great on desktop: MS Windows (Firefox and Chrome / I'm not using/testing MS Explorer, Edge nor Opera) and macOSX-Safari. It also looks impressive on iOS-Safari, but fails to be so fine in Android-Chrome as my geometries are all show in black.

I know this is a problem with my code, as the different PBR examples of BJS look perfect in Andorid-Chrome, but,...what a weird one.

Any starting point with this?

Thanks for your time.

Could you place a repro in the pg ? I guess simply loading one of your material on a plane should do the trick. If this works fine, it might come from you environment map.

Thx

Dear Sebavan:

A problem with the environment was my first thought, but how can be it working on a Platform+Browser combination and not in another one? Non consistent behaviors are difficult to manage/solve.

Best regards.

[Sebavan]

Might be related to webgl version, feature support, float vs half float vs int support and so on, so the combination browser/platform even if not friendly to troubleshoot is yet pretty common.

I ll help solving it if you can repro in the pg.

Dear Sebavan:

I've just checked my development changing my dds (generated with the IBLBaker tool) with the one present in BJS PBR example and now the environment is shown on Android-Chrome.

Anyway, how can I attach my own assets to a PG?

Best regards?

Hi @paleRider

This may be help you with attaching assets.

Hi Arte:

Sadly GitHub seems not support dds files.

We don’t support that file type.

with a GIF, JPEG, JPG, PNG, DOCX, GZ, LOG, PDF, PPTX, TXT, XLSX or ZIP.

Anyway, maybe I'm doing something wrong!

The link to a DDS file should work anyhow (for example - https://raw.githubusercontent.com/BabylonJS/Babylon.js/Playground/textures/environment.dds ). 

[Sebavan]

Can you share the DDS on dropbox or other? I can then repro on my local machine.

Thanks, Sebavan and RaananW for your support.

Presuming this weird behavior must be due to something in the DDS binary format, I'm contacted the guy in charge of IBLBaker project.

He's guiding us in order to solve the issue. I'll let you know as soon as we know something about it.

Best regards.

No problem, but please let us know if there is any trick so that we can add it to the documentation for everybody else :-)
