LICENSE = This kits EULA.
<name>_8k.exr = Native 8192x4096 lat-long HDRI light map.
<name>_1k.exr = Resized version of the 8k to 1024x512 HDRI light map.
<name>_1k.jpg = Jpeg version LDRI (low dynamic range image).
<name>_1280x720.mp4 = Pixar Renderman 17 (or later) plausible turntable
                     render using the 8k exr file as a texture for the
                     background and 1k exr file as the light map
                     for the plausibleEnvLight.
<name>_actual_vs_render.mp4 = This a comparison of an actual Matteo turntable
captured at the scene vs the rendered Matteo turntable.  The actual Matteo
object is 3d print of the sub-div Matteo model used in the render. The Matteo
object is placed in the same location as the camera that captured this light
map. Note this was rendered with depth-of-field and just a dome/env light.
