Iray Sky Pro
Iray Sky Pro Daz 3D model
Iray Sky Pro is a large, layered prop that sits above your scenes and works in tandem with Iray’s sun/sky system to produce realistic-looking skies.
High-resolution cloud textures pulled directly from panoramic image captures are blended seamlessly together, in conjunction with lightweight shading for reasonable render times.
Iray Sky Pro is very simple to use: load the sky pro prop, apply your cloud pattern, and select an appropriate environment preset.
