I’m trying to load 3D model in Chrome headless mode.

– Verge latest version
– Chrome version 75

With some models it goes well, with some others not.

If i try with this example:

http://www.illussimo.com/webgl/myVehicle2018a/my_vehicle_2018.html

this is error log:

and this is the result ( blank screen ):

Any ides, helpful thoughts?

Your example work fine for me : Version 73.0.3683.86 (Build officiel) (64 bits)

"1+1=3... for large values of 1"

I see. I looks like headless Chrome uses SwiftShader software renderer to generate WebGL imagery, and we hit some bug or discrepancy with hardware-accelerated WebGL implementation.

I did some research. There seem to be an old bug reported on Three.js tracker regarding a similar issue.
Here is some related discussion.

I think it might be appropriate to submit another bug report with a narrowed down example to Chromium tracker.
