I’ve just build a system into rdLODtools that allows you to very quickly change the LOD Bias for multiple-selected actors - it makes it very quick and easy to set this.
I’ll hopefully be submitting the update of rdLODtools 1.3 in the next few days.
This is for the editor though - in this instance you’ll probably want to play with the scalability options for your project, you can also set up LOD groups for different hardware (or custom groups for your own).
