I am trying to set my project's background to transparent to only have the cube visible and be able to display HTML elements under it. I tried setting the clear color to transparent by setting the alpha to 0. I also enabled the transparent canvas option in the project settings. I am trying to run the project within a frame in another page.
I tried to figure out by following the steps in this post: (http://forum.playcanvas.com/t/how-to-set-canvas-transparent/2544) but either I didn't do something right or it no longer works.
It also seems like the styles on the frame document cause the background to be gray no matter what.
