This page provides details on the animation export settings in V-Ray for Unreal.
Rendering animation sequences in Unreal is done via the Sequencer Editor. There you can set and animate transforms for actors, parameters for materials, effects, etc. For more information check the Sequencer Editor documentation.
Skeletal and Alembic meshes are not currently supported.
For a step by step guide on how to export and set up a basic animation, see the Animation export QuickStart page.

V-Ray Animation Export Settings
V-Ray animation export settings are accessible from the Render Movie Settings window inside the Sequencer Editor. From the Output Format dropdown menu in the Capture Settings category choose V-Ray animation export.
Settings and parameters from the V-Ray Settings tab still affect quality and performance.
When you finish with adjusting setting, to export the vrscene click the Capture Movie button.
Output Format – The type of capture method will be used.
Custom Render Passes
Image Sequence (png, jpg, bmp)
V-Ray animation export
Frame Rate – The frame rate at which the animation will be captured.
Resolution – The resolution at which the animation will be captured.
Only when V-Ray animation export is selected in the Output Format V-Ray will be used as the render engine. In all other formats Unreal renderer will be used
VRScene Export Options
Render in VRay Frame Buffer – When enabled, the V-Ray Frame Buffer will be used to render each frame.
Render as Draft – When enabled, modified render quality settings (Sample Limit=1, Time Limit =1min) will be used for faster image rendering for quick draft purposes. Accessible only when Render in VRay Frame Buffer is true.
Motion Blur – Settings related to motion blur.
Enable Camera Motion Blur Effect – When enabled, motion blur will be simulated and applied for each frame based on the V-Ray Physical Camera settings.
Geometry Samples – Determines the number of geometry segments used to approximate motion blur. Objects are assumed to move linearly between geometry samples. For fast rotating objects, you need to increase this value to get correct motion blur. Note that more geometry samples increase memory consumption, since more geometry copies are kept in memory.
Image Output – Settings related to image output. Accessible only when Render in VRay Frame Buffer is true.
Auto Save Rendered Frame – When enabled, each rendered image from the V-Ray Frame Buffer will be saved to file. By default, it will be saved in the same directory as the exported vrscene file set in Output Directory in the General category.
Save Color Corrected Image – If checked, the color corrections in the VFB will be baked to the auto saved rendered frames.
Output Format – Specifies in what format the rendered frames will be saved.
Output Directory – Specifies the path where the rendered frames will be saved.
Use VRay Production – When enabled, V-Rat CPU progressive sampler will be used instead of the V-Ray GPU.
Output Directory – Specifies the path where the vrscene and the rendered frames, if Render in VRay Frame Buffer and Auto Save Rendered Frame are true, will be saved.
Filename Format – Sets the name of the vrscene and the rendered frames.
Use Custom Start Frame – Enables the use of a custom start frame for the animation.
Start Frame– Sets the custom start frame.
Use Custom End Frame – Enables the use of a custom end frame for the animation.
End Frame – Sets the custom end frame.
