glow in Brazil?

[ZeBoxx]

I think I would have to know whether you mean glow, emit light, or cause light scattering in its surrounding.

I'll just detail all three cases...

A glow, which is a post-effect (Video Post and Render Effects), can be done just like the scanline renderer with Brazil r/s.
The Brazil r/s Public Test doesn't support g-buffers, though, so you can only 'key off' of the RGB and alpha channels.
E.g. glow only the brightest parts of an image.

To emit light, so that other objects near the object in question get lit up, you coud apply the following material and enable Indirect Illumination in the Luma Server rollout :
- Standard material
- 100% self-illuminating
- Diffuse Map:output
'- RGB level controls the intensity of the light it appears to emit
I'd explore traditional methods first, though.

For light scattering in its surrounding, e.g. as if the object were surrounded by dust/fog that gets lit up, there's no easy solution. A pushed out version of the object with a falloff mapped to it would work somewhat, but you'd really want thick-ness based controls.
Again, traditional methods would probably work better.

excellent reply.

this is pretty much what i want. something like what you get from the Glow Lens Effect.

your point well taken, i think that what i want is either the 1st 2 or all 3.

i want the thing to glow like the lens effect, and also to cast light on objects. i am not sure i totally understand how #3 is different from #1.

i tried the simple Glow Lens effect last night, but brazil ignored it and actually also turned the whole render black. (even in the little video post preview window)

?
