It explores the idea of Ambient Occlusion shading to easily and quickly add realism to Sketchup images via Photoshop. This is done without ever using a rendering engine such as MAX or VRAY. The idea behind Ambient Occlusion is basically a really fast way of adding realism to a rendering by adding shadows in corners where geometry meets.

We can just select all of their faces and remove them (x-key -> 'Faces'). One of the causes of rendering artifacts are the couzinet70's wheel wells - the inner part of the gear housing. Others we have to fix by retouching the final texture. We can work around a few of the problems, indicated by red rectangles. Also, if your final illustration is looking a little flat, its an easy way to add a little punch to it.JS formats for use in Unity 3D, Blender, Sketchup, Cinema 4D, Unreal. Volumetric light, ambient occlusion, bloom, customizable clouds and water.

This time it will take much longer, but the quality of the generated texture will be very high. Increase the 'Samples' value and 'Use Falloff'. Switch again to 'Shading' (F5) and 'World Buttons', and select the 'Amb Occ' tab. After these quick but low-quality passes turn up the quality level for the final texture. Doing the opposite works well, too: deselect all objects and select one fuselage object, followed by 'Select -> Linked -> Material', then one wing object and again 'Select -> Linked -> Material', etc.Tweak the model and render an AO texture as often as necessary until you are happy. We will also deselect all objects that shouldn't really take part in the AO rendering, such as propeller disks or glass.

The example in this tutorial is rather dark for demonstration. It's therefore recommended to not make the AO shadows too dark. We can't compensate for that in FlightGear at the moment. The light is then so much more intensive that the eye pupil closes and, thus, compresses the dynamic range of the ambient shadows. But if the sun shines directly on an 'ambient occluded' region, then we'd still expect that the ambient shadow fades out.
