Hi
After installing meshreder, I got the following warning when run my code.

When I try to render my scence, I got the error...Actually I already installed OpenGL. Thanks for your help.

Are you trying to run this over SSH?

Thanks for your reply. I am working with Windows, running my code in Spyder. What's the possible reason?

That error happens when Meshrender is unable to create an OpenGL context. This is usually caused when pyglet either (A) doesn't have access to a display, or (B) can't initialize an OpenGL > 3.0 context. Without further information, it's unclear what the issue is. Try replacing line 54 (raise ValueError...) with something that just re-raises the actual exception and let me know what it says.

Hi, what if I want to use Meshrender on a server without any display?

@gdwei Check out https://github.com/mmatl/pyrender. You'll need to install OSMesa (check out the docs website) but you can do it without a display now. I'd move to that repo as it's better and will be supported by me in the future.

Hi! Yes, the new code at Pyrender supports offscreen rendering on a headless machine. Check out instructions for getting it working here: https://pyrender.readthedocs.io/en/latest/install/install.html#getting-pyrender-working-with-osmesa

Hi @mmatl <https://github.com/mmatl> , how about the headless server rendering stuff, is the latest code support that? Thanks! — You are receiving this because you were mentioned.
