Anyone know how to make lightboxes or light objects for Mental Ray global illumination in 3DS Max 6.0?

go to object properties (right click on object) and muss around in there.

in the material editor, make a material w/ 100% self illumination.


for GI that kinda stuff is controlled through the render properites, but if you were to say make an object w/ full self illumination, it COULD act as a light source, if one were so inclined to use it as such.

I think he want's the object to emit photons, no?

Sorry. my explanation was annoying.

make sure the object is generating caustics and g.i. under it's properties, instaed of just cranking on the illumination I'd try applying a lume shader to the object and then adjust that. :)

Here's a scene lit with one box emitting photons but a bit too much (blue, white on the grnd plane):

and a scene with the same model but now one of the mats is emitting with a lume shader applied:

shoot me an email and i can send you a scene with just photon emitting sphere floating in it if you want something to dissect or play with.

Actually I was thinking more about light boxes they used on photographs. Thanks for the tips.
Cool bike model, very tron-like on the illuminated one. I'd use that as a WP :)

This is as far as I went on mental ray material and lighting:

I hate the light reflection, that's why i need some lightboxes. also the black one on the top is actually lume in mr material, but I don't know how to set it right.

and this one I tried with my car model:
http://www.geocities.com/aphaits/mrtestcar.jpg
came out good, but lacks reflected objects. Maybe I should try HDRI reflection or something. What do you think?

Absolutely.

Use an hdri image for a bg and apply it blurred to the skylight.

The tronish model uses hdri, you can see the reflection on the buttt of the model.

I like your 4x4 sports car. :)

hmmm, I lokked up HDRI in google and most of it explains that you need to have somekind of fish-eye photo of the preferred environment. How do you set up HDRI?

also, final gather makes the skylight look nice on the objects but it's renders as slow as a dying snail, is there any other way to emulate outdoor skylight? or is my settings incorrect?
