Ray tracing casts simulated rays of light on the scene and is on by default in Blender 2.49. Ray tracing gives the most realistic light properties in Blender, but the renders take the longest. That is why all of my renders in this video will be time lapsed. Don't expect the same rendering times as you see in this video, unless you work for Pixar or the Defense Department. For many animation and game engine applications, ray tracing rendering times are unacceptably slow. In other videos, we will discover alternatives, such as Z buffering, for which response times are more acceptable. However, the effects won't be as realistic as with ray mirror. In this video, we will be looking at a special type of ray tracing effect, ray mirror, which creates mirror reflections.

When a ray of light hits the surface of an object, one of three things can happen. The light can be absorbed by the object, the light can pass through the object (if the object has some transparency), or the light can be reflected back, which is what happens with a mirror. In reality, most objects have a combination of absorption, transparency, and reflective properties. Think of a blue light bulb. The light bulb looks blue because some of the light is absorbed by the material, glass or otherwise, to make it look blue. Perhaps you can see part of the inside of the light bulb, say if it is not frosted, such as the filament. That's because the light bulb has some transparent properties. Finally, if you can see part of the background through the light bulb, that's because of its mirror like, reflective properties. Ray Mirror controls this last property.

how to scale?

[irakrakow]

Select the object (Right click on it). Press the S key. Then enter a number and press Enter. 2 will scale the object to 2 times its size. 0.5 will scale it to half its size, and so on.

[irakrakow]

Absolutely. I'm waiting for the time when 2.5 is more widely used, probably when it is in beta. Right now, 2.49b is still the most common version.

[jamin3d]

Any plans on doing this same tutorial for 2.5?

[irakrakow]

@jamin3d I need to see if the way it is done in 2.5 changed significantly from 2.49. For now, 2.5 is alpha software and can change. When 2.5 is in a more stable release, I'll rewrite it.

hi,

i have a human face mesh that was created using the mirror editing, so one half of the face controls the other half as well, and only that controlling half is visible (highlighted for editing) in the edit mode. when i disable the x-axis mirror the entire other half vanishes. is there a way to make both the halves independent so i can edit them differently?

u sound like gay

How do I get my Ray Mirror to reflect Halos?

Thanks. Its very helpfull, but very slow
