BSP defaults settings for 4.15

Epic team, could you patch BSP in 4.15 to mesh conversion so that “Light Map Coordinate index 0 to 1” is default and “Light Map Resolution” changes to default value of static mesh. This is useful for those who use BSP to create simple meshes so they wont stumble onto black mesh. This is good simple suggestion until Geometry 2.0 replaces BSP.

Best regards.
