the result is brighter than either of the two original

colors.

Additiv e Opacity

Sphere on the right uses additive opacity.

Additive opacity brightens the colors behind the

material by adding the material’s colors to the

background colors. Additive opacity is good for

special effects such as light beams or smoke. You

specify the use of additive opacity on the

Extended

Parameters rollout (page 2–1312)

Additive Opacity and the Alpha Channel

By default, additive opacity does not generate an

alpha value. In other words, the alpha value is zero,

indicating no transparency. This gives correct

results with backgrounds in renderings, but if you

want to composite objects with additive opacity

using video post or a compositing program, you

might want to have additive opacity render with

transparency.Todoso,addthefollowinglineto

the [Renderer] sect ion of the

file, and

then restart 3 ds Max:

To revert to the default method of rendering

additive opacity, in the

3dsmax.ini

file, change the

value of AlphaOutOnAdditive back to 0 (zero),

and then restart 3ds Max.
