KNOWN ISSUES
IBL HOOK SETUP

Known Issues
 
Unsupported Area Light Features:
Constant Falloff

Notes:
Existing area light geometry will be exported to HDR Light Studio when exporting a full scene.
When no background HDRI map is set or is black, strange lighting can occur due to Octane's importance sampling.
 Temporarily turn off importance sampling on the environment if this becomes an issue for you.
