PBR blacked out on android Galaxy S8+ (webgl 2)

[Hersir]

Hi,

found issue with PBR on android device, that have webgl 2.0 support, probably its chrome issue but thought to post it here as well.

Device: Galaxy S8+

OS: Android 7.0

Chrome: 65.0.3325.109

Babylon: v3.2.0-rc.2

GPU: {vendor: "ARM", renderer: "Mali-G71", version: "WebGL 2.0 (OpenGL ES 3.0 Chromium)"}

How to reproduce: any pbr playground will go, as all of them show black meshes instead of pbr materials. PG

It fails without any error or even warning in console.

 

Works fine in native browser (Internet) as it has webgl 1.0:

Internet: 6.4.10.5

GPU: {vendor: "ARM", renderer: "Mali-G71", version: "WebGL 1.0 (OpenGL ES 2.0 Chromium)"}

Unfortunately all the S8 devices I can test on are using android 8.0.0 and using the current version of the pg it all works as expected.

@Hersir Would be amazing if you could update to test ?

Hi @Sebavan unfortunallely its test device and it should remain with specific OS/browser combination for QA to test our products, but I will try to find other device, maybe there is some with Android 8.0. But that makes my probelm even harder, as right now I disabled webgl 2.0 on all mobile devices, but if it works on andorid 8 probabbly will  need to block just andorid 7 or so . Can I debug it somehow to get better understanding what causes it , to have possibility to block just devices that are impacted ?

This looks like the environment texture does not load cause if the shader was fully not compiling it would even not render in black so I would dig around this part by putting other textures in the environment texture.
