Iray Interior Speed Lights contains a suite of tools to speed up your interior lighting process. The culling camera contained in the set will make everything behind the camera invisible, which allows for exterior illumination to pour in. A wide variety of pre-rendered interior room HDRIs are included in this set as light probes.

The HDRIs in combination with the culling camera will speed up your lighting arrangement times and likely limit render times due to decreased reliance on light bouncing. There is also a Key/Fill light included to add sharper, more dramatic lighting to your characters.
