Description
This asset tests the differences in index of refraction between thin-wall and volumetric transmission, using extensions KHR_materials_ior, KHR_materials_transmission, and KHR_materials_volume. The top row of spheres omits the volume extension to cause thin-wall behavior.
The spheres in the bottom row are 2m in diameter with a volume thicknessFactor of 1m, to approximate an average thickness through each volume.
