I purchased Greyscalegorilla's HDRI studio kit. He built rig that allows for .hrdi images to be used to light a scene. For some reason I can't use Cinema 4D's .hrd (no 'i' at the end) files in the rig. Anyone know the difference between an .hrdi and a .hdr file?
Also I would like to make my own .hdri files for lighting. Can I create them inside PS? Can anyone point me to a tutorial?
I have not had any issues with the HDR light kit like you state here.... however; you could just load your file into a material in the lum. channel and load that into the light kit that way.
In addition to that you don't need the light kit to do this you can take the Material with luminance channel set it on a SKY object and turn on Global Illumination.... if you want to avoid GI this will still provide you with great reflections.
