Exporting a .vrscene

A vrscene from the an Unreal project can be exported with in two ways:

VRScene Name – Specifies the name of the generated .vrscene file.

Export VRScene Path – Directory where the .vrscene file is saved. Default directory is <ProjectPath>\Content

Compress – Compresses geometric information thus making the resulting .vrscene file smaller.

NEW

Export Selected Only – Exports only selected actors in the scene to a .

vrscene

file. Option will be ignored when

Light Bake

option is enabled.

Light Bake – Exports separate .vrscene files for every light map atlas.

V-Ray Bake Settings

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>
