After reviewing all the shadow-related posts here, none of them seemed to apply to my issue or I may have just missed it about 10 times.
Check out this link for more information.
I wanted to create a fiddle for this problem, but unfortunately, the version they host doesn't seem to be compatible with my code or the current version of Chrome. I tried changing some elements like .merge and BoxGeometry back to GeometryUtils and CubeGeometry respectively, but that didn't resolve the issue.
My main problem is that I'm not getting any shadows using three.js v .71
I've made sure that all the necessary booleans are set correctly for casting shadows, my scene is within the shadow map boundaries, and I'm using the correct light type. Can anyone help me figure out why I'm not seeing any shadows?
