Hey guys I am new to the Qualcomm AR and Unity bundle and am having trouble figuring out what I need to do to acheive the "hole in the wall" effect where the 3d geo sits "below" the tracker. I successfully have my geo placed and it's tracking amazing, but when the camera is lowered beside the tracker the objects inside of the "hole" render... I'm attaching a pic to help explain.
The way I solved this issue in flash with papervision was to duplicate the "hole" geo, flip the normals, and give it a color of (0,255,0- green) and to make that color "invisible" to the camera. It effectively occluded the geo behind it and worked like a charm! I have tried using the Image Filters in Unity, Color Correction Ramps to be exact, which has a keying function built in, but it isn't supported (or I haven't been able to get it working). Is there something more simple I'm not thinking of in Unity that allows me to not render through, or is my best bet writing a shader? Thanks for the help!
