I have a problem. I'm working with Lightwave for some time, but am not an expert. And I have a problem with rendering. I work with Lightwave 9.0
I have a scene with about 10 objects and 3 lights, nothing too large or complex. I want to use "steamy-shader", so the objects that come into the light will cast shadows behind them, as in the mist.
This works.
The problem is the following: then 10 objects all use the same identical surface, and when I apply the same surfaces to the 8th and 9th item, the rendering suddenly starts off with full-green (instead of black), and the rendering becomes totally purple. This does not happen when I have 7 objects with the same surface and 3 objects that are "bald".
Any idea how to tackle this problem? I have done the rendering before, and that went very good! But now I don't know how to get rid of the green and purple?

Well, I'm having a primary light-source, and I want all the objects that fly through not only to block the light, but also to have their shadow-path visible behind the objects that stretches out behind them.
I use steamer for such an effect, also to increase the volumetric light to create "beams" of shine-through light.
A preview can be seen on:
(had to downgrade quality, and it's in dutch, but essentially it's what I'm trying to animate: the shadows behind the objects and the light that shines through).

For the effect i think your going for, i would just use the volumetric light. With ray traced shadows turned on in your render options, if the light is behind the objects facing the camera, the light streaks should appear from the objects.
