The content in the scene is not visible. I don't see any errors. This worked fine yesterday. Thank you for the good work!
Which nightly build are you using?
It is possible that the content was affected by this recent change to the WebGL specification: https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/doc/spec/WebGL-spec.html#2.3 and this commit implementing the new semantics: https://bugs.webkit.org/show_bug.cgi?id=34766
Thank you for the feedback, Kenneth's suggestion was what I was missing. The content renders perfectly now. I have no further related issues and am closing this ticket. Thank you for your time.
