This article will provide you with a step-by-step description of how to render extreme resolutions with VRayStandalone.
Please keep in mind that the total number of pixels in V-Ray Frame Buffer is currently limited to 2 147 483 647 pixels. For a square image, this means a maximum of around 46340 х 46340 pixels; for a width/height aspect of 2:1, around 65 500 x 32 750 pixels.
Note: Displaying images with more pixels is not recommended because it will occupy too much RAM. For such resolutions, it's recommended to use the VFB preview functionality explained
below.
Step-by-step Guide
1. Enable Auto-Save Image by adding a File Path, File name, and choosing V-Ray Raw Image File (*.vrimg) format.
V-Ray for SketchUp / Rhino: Asset Editor > Render Output > Save Image
V-Ray for Revit: V-Ray > Settings > Renderer > Auto-Save
V-Ray for 3dsMax: Render Setup > V-Ray > Frame Buffer > V-Ray Raw Image File
V-Ray for Maya: Render Settings > Common > Image File Output
V-Ray for Houdini: V-Ray > Render Settings > Images
V-Ray for Cinema4D: Render Settings > Vray > Common > V-Ray Output System
V-Ray for Blender: Properties > Output Properties > Output
2. Switch Image Sampler to Bucket.
V-Ray for SketchUp / Rhino: V-Ray Asset Editor > Render > Progressive Slider off
V-Ray for Revit: V-Ray > Settings > Renderer > Sampler
V-Ray for 3dsMax: Render Setup > V-Ray > Image Sampler (Antialiasing) > Type
V-Ray for Maya: Render Settings > VRay > Image Sampler > Sampler type
V-Ray for Houdini: V-Ray > Render Settings > Renderer > Sampler > Image Sampler > Type
V-Ray for Cinema4D: Render Settings > V-Ray > Image Sampler > Sampler type
V-Ray for Blender: Render Settings > Sampler > Image Sampler > Sampler type
3. Export a .vrscene
V-Ray for SketchUp / Rhino: V-Ray Asset Editor > Export V-Ray Scene File
V-Ray for Revit: V-Ray > Render > Export V-Ray Scene
V-Ray for 3dsMax: V-Ray > .vrscene exporter
V-Ray for Maya: Render Settings > Common > Translator > Export to a .vrscene file
V-Ray for Houdini: V-Ray > Render Settings > Export > Export Settings > Export Mode
V-Ray for Cinema4D: Render Settings > V-Ray > Common > Translator > Export to a .vrscene file
V-Ray for Blender: Render Settings > System > V-Ray Scene Export
4. Open it in text-editing software (like Notepad, for example) and search for:
img_rawFile=0;
img_rawFileVFB=1;
5. Change the values to:
img_rawFile=1;
img_rawFileVFB=2;
6. Open V-Ray Standalone and add the edited .vrscene after the -sceneFile flag:
- Start the Command Prompt by clicking on the Windows start button and typing cmd
-
Paste the following code (the paths per host application are listed at the end of the article):
cd C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2026\bin - Press Enter
-
Type the following code:
vray.exe -sceneFile= \path\to\exported\scene.vrscene

7. Press Enter to start the rendering.
The VFB will open in preview mode to save memory. It won’t show the whole resolution, and you cannot zoom as usual. The image will be automatically saved; you don’t have to save it from the VFB.

8. Once completed, you can open .vrimg in the V-Ray Frame Buffer or use the V-Ray Image to EXR (vrimg2exr) converter to convert the image to the .EXR format, or alternatively, load it to VFB in the platform you are using and re-save from there in the format of your choice.
