Atmosphere Tutorial


Poser 5
Atmosphere
Printer Friendly Version
Requirements...
Poser 5 SR2 or newer.
About 15 minutes
Posing the scene...
Start a blank scene in Poser Load you figure(s) and pose them
Load a prop square and scale it to fill the background of your scene. (Or you could use the Nerd3D Backdrop prop with no texture ;-) )
Click light 1 and then click the Light bulb icon to open the light properties box. ([ctrl] + I)
Take the check off the "On" box
Select light 2 and check it Off as well
Lights Out!
Tip: If you prefer you can just delete the lights that are turned off.
Light Properties
Select Light 3 and open the properties page. ([ctrl] + I)
Put the Dot on "Spot Light"
Set the Atmosphere Strength dial to 1.00

Tip: the atmosphere strength dial allows you to control how strong the atmosphere effect is for each light. This works in conjunction with the Volume density in the Material Setup
Switch to the parameter tab for Light 3. Set the start and end angles. I used 20 and 22.
From the Object Menu select Point At... And choose your figure's head.
Set the light's color
Position the light using the Translate Dials.
Set Spot Light Angles
Material Setup...
Open the material room.
From the Object menu on the Shader Screen pick Atmosphere
Set the Volume density to 0.01
Material Setup
Tip: Think of the density like real world density. A setting of 1.0 would be like a block of concrete. 0.01 is haze, 0.05 would be foggy, 0.1 is like pea soup.
Render Settings...
Default FireFly Production settings will work.
Draft Mode you will need to check "Cast Shadows"
Draft mode settings
FAQ...
My Render is all wahsed out or solid white.
There are a couple of possibilities. The most common is using infinite lights. You should use a spot light. If you need to use infinite lights you will need to set the Volume Density very low.
Another possibility is a spot light that is set very wide The more light passing between the camera and your subject the more faded it will look.
My light doesn't show at all.
Four possibilities here. Starting with SP3 a new dial was introduced on the light properties. This dial gives individual control over the light atmospheric effect. The default setting for this dial is zero or no effect. Set it to 1.000
The Volume density may be set to low in the material setup. 0.01 is a good starting point.
You have to use the Fire Fly render. The P4 render engine doesn't do volume, sorry.
There must be something behind the figures for the volume to show up. A prop Square scaled to fill the window will work.
