Additive Level - Brush Hollow Option

[cydonian]

Anyone know how to set an imported brush as hollow when working in an additive level?
Is this something that has to be set in the ASE exporter?

I believe all "additive" brushes are set to "hollow" by default since it is an additive scene you are doing.

Theres an option in the Brush Builder settings that you can check on or off to allow double sided walls. Its useful for building rooms that one can walk in and out of in an additive world. Its off by default.
