Title: Mental Glow Tubes
Name: Jonathan Grace
Country: Denmark
Software: 3ds max, mental ray

This is one of a series of attempts to create mood in a scene with glowing objects. No lights were used, only mental ray glow shader. I would like to know if anyone else has had experience/know-how to emit light from objects with mental ray without a lot of atrifacts.
Comments are welcome.

Interresting idea and good lighting!

I only use Maya but i think you can apply similar settings in 3dsmax:

Maybe you can advance your light in the room with well placed area lights. Use Final Gather only for the less important bounces. You need at least 4-5 Bounces for a scene like this.

For the case you hate Arealights, try to decrease the FG min/max radius. It is good to have the min radius at the size of one pixel of your Render resolution. This is at cost of renderspeed so don't expect to render a room like this in less than 10 min with a Vray look.

Hope that helps.

Hey thanks for the tip, when you say the Vray look, do you think this glow effect could be easier to achieve with Vray? I guess I'll run some tests and see...:thumbsup:
