Does anyone know of a way to have two active cameras for coppercube webgl game? Any working splitscreen methods for the platform? If i can get two cameras running i can have Webxr support for the platform in no time. thanks!

Serious replys only please, working hard at getting the community full webxr support. It is currently working with a published coppercube html.

I don't think there is a clean way of doing that without modifying source copperlicht code.
If you're making a simple scene, what you can do though is use two ccbz files like:<script type="text/javascript">
<!--
startCopperLichtFromFile('3darea', 'copperlichtdata/lll.ccbz', ...;
startCopperLichtFromFile('3darea2', 'copperlichtdata/lll1.ccbz', ...;
-->
</script>
And two canvas elements correspondingly:
<div align="center">
<canvas id="3darea" width="800" height="600" style="background-color:000000">
</canvas>
<canvas id="3darea2" width="800" height="600" style="background-color:000000">
</canvas>
</div>
You build one file to be sort of "primary" frame, there all game logic happens, second is "secondary" which has the same assets, same everything but no logic at all, you copy nodes positions, scales, rotations, animations and other parameters from primary file instead. I never tried that, but I believe canvas gets updated even if it's not in focus, so potentially it should work.

I appreciate your reply Smoke, but unfortunately it won’t work because then there would be two different gl contexts and the webxr session can only use one and one canvas. Need some way to mirror the right vr eye onto the left eye.

I see. Unfortunately, I don't know much about webxr. Have you tried to download and modify CopperLicht to support it?

Yes, thats what i am currently doing. Ive added a lot but ijust dont know what to change specifically that will allow two cameras or allow the engine to renderer twice once for each eye. really just stuck there i can handle headset tracking and motion controllers input, but im just only stuck because it just reanders to the right eye. It does clear the buffer for the left and sets the background color for it, but the actual scene only renders to the right or to just the left vice versa.

So I got them both to render now but again one small issue is they are at two slightly different angles which causes the scene not to line up correctly and Im seeing double. But im working on it.
