Hi folks,

I've been experimenting with the ambient setting in the material room...

In the picture I posted today, I set the ambient setting of the light saber blades to 10.000. When rendered, the blades give off a glow as if they were point lights.

But, while the blue blade stayed blue, the red blade turned yellow. I tried playing with the diffuse and other color settings, but I couldn't make it turn back to red. And the glow (on the characters shirt and face) still looks red.

Does anyone know where I can find an explanation of how the material settings work? (Paging Dr. Geep.... ?)

Thanks,

Tom

You need to supply more information, especially the render settings you used.

Incidentally, you need to turn off the shadow setting for the blades.  Self-illuminated objects don't (generally speaking) cast a shadow.

Try rendering with tone mapping set to "HSV Exponential", that will prevent burned out colors out of superbright objects.

as ment. by stewer, an overlit red will be blown out as yellow.  same thing happens with human skin renders in poser 6 and earlier without GC or HSV/ETM - if there are too many bright directional lites, one will see yellow patches on the skin.  the exposure control helps with renders that have wide variations in apparent luminance.

Overlit "orange" will blow out as yellow - pure red will not.

You must have some green in there as well as red.

Suppose you have Red = .9 and Green = .1.

Then with Ambient_Value = 10, you multiply both by 10.

You get Red = 9, and Green = 1.

Since Red = 9 is a hypercolor (because a monitor cannot display red above 1) this displas as Red=1 and Green = 1, i.e. Yellow.
