UberVolume is an interior volume shader (in prman speak) for DAZStudio that allows you to produce a variety of Smoke/Fog/Mist/Cloud affects.
UberVolume can be used in several different ways. In order to create a volumetric spotlight, follow these steps:
- Create a Spotlight (1)
- Double-click the 'Parent Cone to Light' or one of the others marked with 2 in the above image.
If you would like to apply one of the look presets, you can then:
- Select the SpotLight 1 Volume (3)
- Go to surfaces and select the SpotLight 1 Volume (4)
- Double-click on the !Uber Volume Dust, Cloud, etc to apply (6 in the image)
- Select whatever effect you want to produce, these can be edited in the surface for strength etc. See below.
Bellow is a description of the various controls of UberVolume.
- The Color of the Volume
- The Density of the Volume; The higher the value the more difficult to see through the volume.
|Density 0.01||Density 0.02||Density 0.05|
- Volume Start/End
- Min/Max distance the light will penetrate the volume. Leaving these values small/large will ensure the entire volume is used.
- Step Size
- This is the main speed/quality control and represents how often the volume is sampled along the light ray. Small values will mean many samples and smooth transitions; Large values can lead to grainy images and fast renders.
|Step Size 1.0||Step Size 8.0|
- The Color that is scattered, tinting the background the complementary (opposite) color of the scatter color.
|Scatter Blue||Scatter Orange|
Adding smoke will add a 3D noise texture to the Volume.
- This is a mix value between an even volume and the smoke pattern.
|Strength 0||Strength 50||Strength 100|
- The amount of detail in the smoke. Low detail can look puffy while high detail can look more wispy.
|Detail 1||Detail 10||Detail 20|
- The size of the noise pattern. Large scale can look more like clouds while scale values can produce a dusty look.
|Scale 1||Scale 10||Scale 20|
- The Contrast between the smoke/empty areas. A high value produces hard transitions.
|Contrast 1||Contrast 5||Contrast 20|
