Ok, I recently did a commercial for my sister's organization. I used some volumetric lighting effects for there logo; the basic streams of light coming out of the letters. This isn't really a technical problem, but just a thing that I noticed. The camera at one point moves through the light. I used an image map to make the letters stream out light, but here's the thing. When the camera moves through the light, you can see divisions of the image map. I guess I could explain it as if I were to make a bunch of four-sided polygons; all facing the camera, and parallel to each other. Each one seperated on the Z-axis to the camera a little bit. Each polygon has the same texture, so when you look at it from a distance, it looks like a volumetric light, but up close, you can see the "fakeness". I was just wondering if this was a defect, or is it the way Lightwave render's volumetric lights that have image maps applied to them. Thank you.
