Redshift allows the results of the Ambient Occlusion node to be connected and combined with other rendering techniques which provides the user with a very good degree of flexibility. This is the place for Arnold renderer users everywhere to ask and answer rendering questions, and share knowledge about using Arnold, Arnold plugins, workflows and developing tools with Arnold. Using it to implement techniques like 'dirtmaps' where shading is modified around occluded areas by blending different textures (such as moss).Creating extra darkness/contrast in occluded areas for artistic reasons – when GI has failed to do so and has 'leaked' too much lighting in these areas (because of multiple bounces).However, Ambient Occlusion to achieve different effects such as: This reduces the usefulness of ambient occlusion as a primary lighting technique. Ambient occlusion can be used to enhance shadows in renders. As mentioned in Basic Compositing in Post Production I will go through how I create an ambient occlusion material and use it in Photoshop. Today's computers are much more powerful than when Ambient Occlusion was first developed and the use of global illumination is now the norm. 3ds Max, Ambient Occlusion, How To, Photoshop, Post Production. Instead of shooting many rays and bouncing them around (which is what is needed for global illumination), ambient occlusion was used to detect the parts of the scene that are occluded from the rest of the environment (such as corners and creases). Ambient Occlusion (AO) is a shading technique that was developed back in the time when global illumination was impractical.
