Enabling DBR renders completely black with default lighting.

[DPS]

As per title - my render is completely black when enabling DBR with the default lighting.

If I switch off DBR it renders fine. If I switch on GI and the Vray environment it renders fine with DBR.

Default Lighting is not supported by DR and it is automatically turned off when DR is activated.
In order to avoid black-results it is always recommended to place some lights in your scene before sending it to DR.

Ok - fair enough. Thanks
