This page provides detailed information on Viewport Render in V-Ray for SketchUp. Overview Viewport Render (VPR) is a render output overlay visible in SketchUp's viewport. It updates upon scene updates during interactive rendering It is rendered. VPR can either overlay the entire viewport or render over selected regions. UI Paths ||V-Ray Frame Buffer|| >  Region render ||V-Ray Frame Buffer|| >  Start Interactive Rendering ||V-Ray for SketchUp Toolbar|| >  Render Interactive ||V-Ray Legacy Toolbar|| >  Viewport Render SketchUp Menus Ribbon ||Extensions|| >  V-Ray   >  Rendering  >  Render Interactive ||Extensions|| >  V-Ray   >  Rendering  >  Viewport Render Accessing Viewport Render from the V-Ray Toolbar or the V-Ray Menu in SketchUp 2023 or later versions opens the following notification. ||Window|| >  Default Tray  >  Overlays  >  V-Ray Render Workflow First, activate the  V-Ray Render  in the  Overlays  menu. Then start an Interactive render. Closing the V-Ray Frame Buffer does not stop the Viewport Render.   The Render Output does not automatically fit the viewport resolution. Adjust the resolution from the  Asset Editor  >  Render Settings  >  Render Output  and set the  Aspect Ratio  to  Match Viewport . You can either adjust the  image's Width  and  Height  to match the  Aspect's Width  and  Height  or resize SketchUp's window and press the  Update  ( ) button.

If you wish it to do so, go to  Asset Editor  >  Render Settings  >  Render Output  and set the  Aspect Ratio  to  Match Viewport . You can either adjust the  image's Width  and  Height  to match the  Aspect's Width  and  Height  or resize SketchUp's window and press the  Update  ( ) button. Select only a region in the viewport to be interactively rendered from the toolbar button or from the V-Ray Rendering submenu. Multiple regions can be selected while the VPR is running. Control of the render overlay opacity is done through Ctrl and ‘+’ or ‘-‘  keyboard shortcuts, so you can decide how much to blend it with the SketchUp regular viewport.  Shift  key adds a region to the existing one, while  Ctrl  key selects a new region discarding the previous ones. Example: Region V-Ray Viewport Render Example: Reduced render overlay opacity Notes Use 'Ctrl' plus '+' or '-' key combination to control overlay opacity. V-Ray Vision  is an alternative to the V-Ray Viewport Render and can be used instead. However, V-Ray  Vision is currently not directly available in the viewport.
