![]() Blade Angle: One can also set the angle with the blade_angle parameter, which is expressed from 0.0 to 1.0 where 0.0 is zero degrees and 1.0 is 360 degrees. With bias at 4, notice the 4 corners in the blurred highlights. With bias at 0, notice how the blurred highlights are perfect circle. A value of 0 will result with No Bokeh. The higher the value, the further away the Blur will accrue.įrom left to right, Radius at 1.0, 0.5 and 0.0 Samples: The more samples we have the better the quality of the “blur”, however that comes with the expense of render time.įrom left to right: Sample at 0, 24 and 48 Bias: Lower values push the sample probability towards the center, creating a "softer" looking DOF effect with a more "misty" look. Higher values push the sample probability towards the edge, creating a "harder" looking DOF where bright spots actually resolve as small circles.īlade Count: This defines how many "edges" the "circle" of confusion has. A zero value makes it a perfect circle. Notice the shape of the highlight in the blurred area of the rendered image. Radius: This is the radius of confusion. This is an actual measurement in scene units. You can also use the camera Near/Far Clipping plane as a method to determine the distance required. To get the proper Plane value, we will use the measuring tool to give us that distance from the camera to the point of interest. This point will be in focus and the rest will be out of focus. Plane: Is the distance to the focal plane from the camera, i.e. the point of interest. You can apply an render layer override to disable the shader for specific render layers, for instance. On: This is a toggle on/off switch to disable the Shader if needed. Default is on. ![]() Note: The Shader parameters rely on the scene size, therefore results will vary from one file to the other. Under “Create Render Node” dialog, open the “Lenses” vertical tab and locate the mia_lens_bokeh Shader.īy default the Bokeh effect will look something like this How to simulate Bokeh Lens effect in Maya Assign Lens shader to Camera We start by selecting the camera of choice, and under the attribute editor of that camera, click on “Lens Shader” ![]() 1 How to simulate Bokeh Lens effect in Maya. ![]() This is the render without using Bokeh as our starting point.Īfter Once mental ray Bokeh Lens Shader is being applied to Maya’s Camera, it will produce the following effect, and much more! We can simulate the same effect in Maya using the Bokeh Lens Shader in mental ray. For some real life examples, please visit the Bokeh page on the Wikipedia. Different lens Bokeh produces different aesthetic qualities in out of focus backgrounds, which are often used to reduce distractions and emphasize the primary subject. Bokeh Lens Shader by Ash Aiad Autodesk Media and Entertainment Division Bokeh is a Japanese word for “blurred or fuzzy” (暈け) This is a real life phenomenon that occurs in photography where the light sources in an out of focus area of an image. ![]()
