UberVolume is an interior volume shader (in prman speak) for [[DAZStudio]] that allows you to produce a variety of Smoke/Fog/Mist/Cloud affects.

== User Guide ==

=== Setup ===

[[Image:UberVolume_step_by_step.jpg|500px]]

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.

=== Basic Controls ===

Bellow is a description of the various controls of UberVolume.

;Color: The Color of the Volume
;Density: The Density of the Volume; The higher the value the more difficult to see through the volume.
{| border=1
!  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.
{| border=1
!  Step Size 1.0  !!  Step Size 8.0
|-

|}

;Scatter: The Color that is scattered, tinting the background the complementary (opposite) color of the scatter color.
{| border=1
!  Scatter Blue  !!  Scatter Orange
|-

|}

=== Smoke Controls ===

Adding smoke will add a 3D noise texture to the Volume.

;Strength:This is a mix value between an even volume and the smoke pattern.
{| border=1
!  Strength 0  !!  Strength 50  !!  Strength 100
|-
| [[Image:UberVolume_density02.jpg]] || [[Image:UberVolume_smoke050.jpg]] || [[Image:UberVolume_smoke100.jpg]]
|}

;Detail:The amount of detail in the smoke.  Low detail can look puffy while high detail can look more wispy.
{| border=1
!  Detail 1  !!  Detail 10  !!  Detail 20
|-
| [[Image:UberVolume_smoke100.jpg]] || [[Image:UberVolume_smoke100_detail10.jpg]] || [[Image:UberVolume_smoke100_detail20.jpg]]
|}

;Scale:The size of the noise pattern.  Large scale can look more like clouds while scale values can produce a dusty look.
{| border=1
!  Scale 1  !!  Scale 10  !!  Scale 20
|-
| [[Image:UberVolume_smoke100_scale01.jpg]] || [[Image:UberVolume_smoke100.jpg]] || [[Image:UberVolume_smoke100_scale20.jpg]]
|}

;Contrast:The Contrast between the smoke/empty areas.  A high value produces hard transitions.
{| border=1
!  Contrast 1  !!  Contrast 5  !!  Contrast 20
|-

== Tips and Tricks ==

* [[Image:Alert.png]] One of the limitations of an ''interior shader'' is that the '''camera cannot be inside the volume'''.  Otherwise the atmospheric effect goes away.
* Give your volume color by using lights that support texture maps/gells like [[UberSpot]] and [[UberPoint]].
