When Interactive Rendering is enabled, use the drop-down list to choose between displaying the interactive rendering in the Thea window (see right) or in SketchUp as an overlay (see below).
‘With edges’ mode is especially well-suited to interaction with SketchUp models. This mode temporarily modifies the SketchUp display style to clearly show edges in exterior/interior models. You can navigate, modify materials, add models, and see the changes take effect in SketchUp while rendering.
‘Blended’ and ‘Multiplied’ give you full freedom to set up SketchUp style. ‘Blended’ works best with dark backgrounds and bright lines (like ‘With edges’). ‘Multiplied’ is the opposite and works best in hidden line mode with a white background.
The rendering can be saved as an image, both in standard and overlay modes.
Tip: While using the overlay and modifying a model, the best results can be achieved with Presto engines using only GPU for rendering. CPU shouldn't be used, but should be made available to SketchUp.
Interactive rendering in the SketchUp window allows you to render a selected area of your scene. When interactive rendering is on, hold down the Shift key while clicking and dragging to select the desired area. Multiple regions can be displayed at the same time. You can also save an active region by clicking on the Save button.
After rendering, you may decide to edit a specific region. Instead of re-rendering the entire scene, you can re-render just the region. Right-click and drag to select the region to re-render. The selected region will be outlined with green dashed lines, and its size will be displayed.
Please note that although the whole image will be displayed, the display settings will only affect the selected region. In general, it is not recommended to modify the settings, as the result will not match the original image.
The entire image can only be saved in non-HDRI formats. The region can be saved as an Exr, img.thea, or HDRI.
