LightMass Assistance Required

Hi guys!

Just working with the DataSmith Beta which is truly making things SO much better and faster. However I am struggling with my own skills on the Lightmass problem I am having. Lighting in Unreal is my weakness. I only have the one light source at the moment which is a Vray Sun.

I have imported a large scene from 3DS Max + Vray into Unreal V19 via Datasmith and worked great, but I am getting the following issue(s) below for the Lightmass. Can someone please advise or even directly assist via TeamViewer and show me? Would be HUGELY appreciated!


Ok so I did as you advised and it began to work then I got this error. Any idea where I see what is the issue? Or how to resolve? Really appreciate teh active assistance!
