Overview

VRayScene allows for assets to be shared between all platforms that run V-Ray.

Exporting a .vrscene

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

V-Ray toolbar

ІІV-Ray toolbar drop-downІІ > Export vrscene

VRScene Name – Enables the export of a .vrscene file when the V-Ray render button is clicked.

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.

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>
