I'm using Photoshop CC 2015 and I'm trying to render a lighting effect on an image for a project but it's grayed out. I'm on a 13" late 2013 MacBook Pro retina display running OS X El Capitan with a 2.4GHz Intel i5 processor, Intel Iris graphics card with 1.5GB of video memory, 8GB of RAM, and 256GB of flash storage.

Is your image in 8 bit/channel RGB mode?
Are the 3D features enabled on your system, or are they disabled because the GPU doesn't meet the minimum requirements?
