An Opacity value of 0.0 is fully transparent. An Opacity value of 1.0 is fully opaque. Transparency can be very time consuming to get absolutely correct. As such, Voxler contains several different algorithms that trade off speed against correctness. See the View | Transparency Type options if the transparency does not look correct for your particular data. Usually the Sorted Object, Sorted Triangle Add and Sorted Object, Sorted Triangle Blend methods result in good output but these methods are significantly slower than the other methods. A quick method that produces good results in many cases is Blend or Delayed Blend.
