Description
This asset contains the five canonical Needle Cloud HDRI preview spheres in a horizontal row. The materials are, from left to right: transmissive glass, white diffuse, chrome, rough metal, and glossy green. It is intended to make environment-map lighting, reflection, roughness, metallic, and transmission differences easy to inspect in viewers and conversion pipelines.
