How to make Area Light totally invisible to GI ?

[SSmolak]

Hello,

Even if I put all options in Octane Area light to be invisible to camera, shadow etc it is still visible to GI generated by Octane Sky for example. If such Area Light plate is 5cm above ground, ground is still obscured by this Area Light even if I disable this Light ID in ground Octane Object Tag. Octane Sky still can't pass throught this Area Light object - there is still visible GI shadow under this light on the ground.

you dont have Octane Sky in scene. If you will have it - you will have dark area under area light Or light from that area light is gone
