Q: I'm
looking for a way to apply glow effect from video post to only somme area
of a bitmap
I've tried a Mix material (in diffuse map) componed of
- one bitmap
- one Mask bitmap set with the same ID MAT that i set in the
video post
but it doesn't work ...
(5/29/98) a
A: The MatID has
to be set not in the Mask bitmap, but in the Diffuse map instead.
The Mask is only used to define which part of a Map/Material should
be displayed on a certain position. The MatID is carried by the Map itself.
An example:
Say you need a marble material that has glow only partially applied.
-
Take a Standard material
-
Apply the Marble Bitmap to the Diffuse channel
-
Apply a Mix map over the Bitmap.
-
Copy the Marble Bitmap to the second channel of the Mix map
-
Go into the second Bitmap entry and set the MatID to 1
-
Add some mask bitmap (for example Checker Map) to the Mix Control channel
of the Mix Map
-
Open TrackView.
-
Add a Scene entry
-
Add a LensFX Glow
If you execute now, you will get Marble texture all over the object, but
glow only where the MatID 1 is....
