Hi!
I am working on an underwater scene in XSI 3.0.1.
I made a small submarine with a searchlight in front.
The searchlight is a spotlight. To make it look more realistic, i added the volumic-shader so that the searchlight has a visible cone.
After the scene was rendered i realized that the cone disappeared slowly from frame 93 to 131 as if it was slowly pulled back into the spot. At frame 1, where the cone is visible, the sub is outside my underwater-landscape which i modeled from a polygon-grid using a weight-map. The cone disappears when the sub gets near the edge of the landscape grid. I positioned a spot inside the landscape but there it doesn't work either. I have another volumic spot in the scene wher the cone is always visible. It is positioned above my water grid which is deformed by an animated wave-control-object. I use it to create underwater light effects.
What can i do to make the searchlight-cone visible all the time?
Thanks,
Patrick
