To use native AO, you must first ensure you are using the in Preferences > Graphics . Once active: Go to the Styles panel. Click the Edit tab and select Face Settings . Check the box for Ambient Occlusion . 2. Mastering the Settings
The percentage of blocked rays determines the darkness of the pixel. This is why AO is computationally expensive—it requires firing thousands of rays for every single pixel in the image to simulate the softness. SketchUp users often notice that enabling high-quality AO slows down the "panning" and "orbiting" of the model significantly because the computer is constantly recalculating these ray intersections. sketchup ambient occlusion
Crucially, these renderers separate AO from global illumination. In V-Ray, for example, one can produce a “dirt map” (a common synonym for AO) that darkens corners without affecting the overall light balance. This is invaluable for architectural interiors: the crevice where a skirting board meets the floor no longer appears as a floating line but as a grounded, shaded recess. The difference is the visual equivalent of hearing music in stereo versus mono. To use native AO, you must first ensure
For photorealistic visualization, SketchUp relies on an extensive network of render plugins. Here, ambient occlusion is not an afterthought but a cornerstone. Engines like , Enscape , and Thea Render feature dedicated AO parameters. In these environments, AO functions as a render element or post-process effect . The designer can control the occlusion radius (how far the shadow spreads) and intensity, often layering the AO pass over the final image to enhance detail. Check the box for Ambient Occlusion
In traditional rendering terminology, Ambient Occlusion is a shading method used to approximate the way light radiates in real life, especially when considering indirect illumination (Global Illumination).
AO is essentially a calculation of accessibility. If a surface point is surrounded by geometry (inside a corner), it is "occluded" from the sky, so the renderer darkens it. If a point is on top of a table, it is "exposed," so it remains bright.
