Import vrscene Dialogue
The V-Ray Scene Import Options window appears when you are importing .vrscene files into Unreal.
Create Assets - Enables the creation of static meshes, materials and textures in the Content Browser.
Treat Y-axis for Up Vector - Enable this if your vrscene was generated from a software that has its Y-axis set as an up vector (e.g. Maya)
Use Full Proxy Mesh - When enabled, proxies will be imported as static meshes.
Create Actors - Enables the creation of actors in the level.
Create Nodes - Enables the creation of static meshes in the level.
Create Lights - Enables the creation of lights in the level.
Create Cameras - Enables the creation of cameras in the level.
Build Lighting - When enabled, the Build Lighting Only command is executed at the end of the import phase and Unreal begins lightmap baking.
Light map options
Big Resolution - Specifies the maximum number of big resolution (2048) lightmaps that can be set in the level. (e.g. multiplier of 1 will result in 2 meshes that will have a lightmap resolution of 2048; multiplier of 2 will result in 4 meshes that have lightmap resolution of 2048)
Small Resolution - Specifies the multiplier for the number of low resolution (16) lightmaps that can be set in the level. (e.g. multiplier of 0 will set the minimum lightmap resolution of a mesh to 8; multiplier of 1 will set the minimum lightmap resolution of a mesh to 16)
