The lighting in the Esenthel demo is not working for Windows Chrome. A bug report was filed here:
https://code.google.com/p/angleproject/i...ail?id=902

but the ANGLE developers need a smaller test case.

Thanks for reporting the issue.
This was working fine before on Chrome, and since nothing was changed on the demo side, then the issue is definitely on Chrome side.
Unfortunately I'm too busy at the moment to try provide a simpler test case.
Note - it doesn't look like just specular is missing, it looks like the entire lighting is missing.
Even the simple diffuse base - Dot(light, normal).

The demo is also broken in Firefox now too.

Could you offer any suggestions to the FF developers?

Specifically they wanted to know if you could post the source to the lighting shader?

Hello,

I've noticed that as of today Chrome is working fine, and based on your link, Firefox should be OK with next version (38).
