Lightmap Atlas resolution – Sets the preferred atlas resolution. Note that static meshes that have larger Light Map Res will automatically resize the atlas.
Dilation – The number of pixels to expand around geometry UVs.
Export VRScene – Enables the export of a .vrscene file when the V-Ray Bake button is clicked.
Export VRScene Path – Directory where the .vrscene file is saved with the file name bake#.vrscene. Default directory is <Project_Path>
NEW - Export EXR – Enables the export of a .exr file for each Static mesh Actor in the level when the V-Ray Bake button is clicked.
NEW- Export EXR Path – Directory where the .exr files are saved with the file name <StaticMeshActor_Name>.exr. Default directory is <Project_Path>/export
NEW- Override Light Maps – Enables the loading of .exr files for Static Mesh Actors in the level when the V-Ray Bake button is clicked.
NEW- Override Light MapsPath – Directory from where the .exr files are loaded when the V-Ray Bake button is clicked. Default directory is <Project_Path>/override.

tip
If you want to have Export EXR optionenabled before the bake afterwards you can rebake only selected actors without the need to bake the whole level. After the initial bake you can copy the .exr files from the directory specified in Export EXR Path to the directory specified in the level Override Light MapsPath. After you made your modifications to the actors (e.g. increase Lightmap resolution) enable Override Light Maps option and then delete the appropriate .exr files (<StaticMeshActor_Name>.exr) from the directory specified in the Override Light MapsPath. When you click the V-Ray Bake button , the atlases for the actors will be loaded from the Override Light MapsPath folder and only the Actors that do not have according .exr files will be baked.

You can use the Export EXR and Override Light Maps options to have a resumabe lightbake. When Export EXR is enabled after each atlas bake .exrs are saved inExport EXR Pathdirectory. In cases of a crash or something else you will not lose your progress. Just copy the .exr files from the directory specified in Export EXR Path to the directory specified in Override Light MapsPathand atlases for the other actors enable the Override Light Maps option. When you click the V-Ray Bake button the baked atlases will be loaded from the Override Light MapsPath folder and the bake will continue from when it has stopped.

Large Atlas Resolution values speed up light baking but increase memory consumption.
