This page provides details on the V-Ray for Unreal UI and how it is integrated into the Unreal interface.

 

 

 

Overview


The V-Ray for Unreal toolbar gives you access to all of the settings and options available in V-Ray.

The V-Ray toolbar allows you to render using V-Ray’s Interactive renderer, open the V-Ray frame buffer and access the V-Ray Settings tab.

 

 

V-Ray Assets Category


The V-Ray Assets category in the Modes tab allows you to quickly create V-Ray related actors:


 

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)
