Free Sample: Imperfect Aperture Maps For Perfect Cgi Bokeh is a free aperture map from Add Your Light for Blender artists using depth of field. In many modern rendering engines you can change the shape of your camera's aperture to affect how out-of-focus areas render. This sample plugs into your virtual camera so you can shape that aperture and get bokeh closer to what a real lens produces in photography, including the option to add dirt or chromatic aberration to the shape.
A Blender camera rig for custom bokeh is included, and the rig file ships with an HDR from Poly Haven under a CC0 license for testing purposes. The maps are compatible with Cycles, V-Ray, Corona Renderer, Octane, Arnold, Frischluft Lenscare, DOF Pro and many more. If the sample suits your work, the full pack offers 95 different high-resolution aperture maps.
Distributed under a GPL license and compatible with Blender versions from 2.6x through 4.0, it earns its place in the superhive library as a free way to experiment with aperture-driven bokeh. A tutorial and a demo video are available for setting it up in Blender.
