Affects the accuracy of the blur effect by controlling the number of samples per shading point. With
a value of 100%, the maximum number of samples dened under Max Samples will be used in critical
areas. Lower the value to reduce the number of samples used.
Min Samples / Max Samples
These parameters will only be available if Dispersion is set to a value higher than 0%.
Increasing Min Samples and/or Max Samples gives a higher quality blur, but a longer render time
also.
CINEMA 4D uses samples to create the blur effect. Rather than take samples at even distances, the
samples are concentrated where they are most needed. Max Samples denes the number of samples
used for the most important areas. Min Samples denes the number of samples used for the least
important areas.
If you see black areas when rendering overlapping transparency objects, increase the Ray Depth value
on the Options page of the render settings. If you can’t see weak reections in the render, ensure that
Threshold is set to 0%. You’ll also nd this parameter on the Options page of the render settings.
Reection
If there are many reective objects in the scene, you may notice that shadows do not appear in the
reections on some of these objects. To make the shadows appear, increase the Shadow Depth value
in the Render Settings (Options tab).
