Adjust the size of the glow object
Create glows, halos, or lens flares
Create illuminated fog
Create environments that glow
When
you first open Hypershade, three nodes are
available by default in the Materials tab:
lambert1, particleCloud1, and shaderGlow1.
Use the Shader Glow node
for environment glows.
Shader glow from one surface can affect the
intensity of another surface’s glow. For example, a large glowing
surface that enters a scene may appear to cancel the affect of,
or alter, the glow of a smaller surface in the scene. This phenomenon
is caused by the Shader Glow’s Automatic
Exposure setting.
NoteThe
Shader Glow node’s
attributes are the same as the
Optical FX’s attributes.
See
Optical FX Attributes.
To
get the right glow and halo intensities using Shader
Glow
- Turn
on Auto Exposure in the Shader
Glow’s Attribute Editor (open the Shader
Glow Attribute Editor by double-clicking the Shader
Glow swatch located in the Post Process folder
in Visor’s Rendering section).
- Select
a frame in which the halo and glow effects have the look you want.
- Render
the scene in Render View.
The glow intensity normalization factor and
halo intensity normalization factor are printed in the Maya command
shell or DOS window. They look similar to this sample:
glow intensity normalization factor = 0.0110171.
halo intensity normalization factor = 0.0243521.
These are the values Maya uses if Auto
Exposure is turned off.
- In
the Shader Glow’s Attribute
Editor, set the Glow Intensity and Halo Intensity to
the values for the glow intensity normalization factor and halo
intensity normalization factor.
- Turn
off Automatic Exposure.
- Render
the scene again at full resolution of your intended output.
