I am using Carrara 1.1 and I am trying to set up an animation of a projector projecting a movie onto a screen. I got the models for the projector and the projection screen off of the included resource disc. I then placed a spot light just in front of the projector pointing at the screen.
The first problem I had was the shape of the light being circular. I have solved that by creating a square mask and applying that to the spot. I then thought it would look best if there was some faint volumetric light coming from the projector so I added that as well. The problem I am having is that the volume lighting does not interact with the screen. It just goes on through the screen. I need it to stop at the screen. I cannot figure out how to make the lighting stop at the screen. Is there a way to adjust the length of the light? I have been looking through the maanual and the various options on the light and cannot seem to figure it out.
Is there a better way to do what I am trying to do? Is there a way to have the light actually project the movie clip or do I need to just apply the clip to the screen as a material?
Any help would be appreciated.
Thanks.
