I'm trying to add a spotlight on a per-pixel basis by using projected
textures as it says in the pfLightSource reference page, but I can't get
it work. I want a spotlight pointing at (0, 0, -1) direction, so I
attach the lightsource to a DCS wich points to the right direction. I
don't know the way this affect to the Frustum of the lightsource.
Has anybody got succesful with this kind of spotlights? I'm interesting
in the way the pfFrustum and the texture (size?, type?) affects the
lightsource behaviour.
I'm using Performer 2.1 on IR. (by the way, in the pf2.2 programming
manual the projected texture spotlight don't appear in the "Creating
Visual effects" chapter as it does in the 2.1 manual. Is this feature in
another place or it is not longer being supported in 2.2?)
Thank you for any help.
