So am wondering if there is way to bring ThreeJS as canvas into Phaser?
not trying to be rude or anything, but this doesn’t help. the demo on there is returning a 404 not found. 
I haven’t looked deeply into it, but I think I remember you have requested links (because of Google censorship in your country or something). The Reddit post outlines a procedure that can be used. I didn’t even know there was a demo.
