After using Maxwell multilight for some time, I wanted similar functionality inside max with any render.

So I started to create a script for it, right now it work with Vray, but i can easily add other renders.

For those who are not familiar with Maxwell Multilight, itís a render mode in which you basically have all the information from each light source and after render you can change the light intensity and also animate it.

Here are 2 of screen shots and a quick video demonstration.


I will be updating my webpage with some information and videos as soon as I can.

A brief description of how it works.

Render section.

- Set groups of whatever lights, vraylightmaterials, environments etc
- Render it locally or Network render



- Intensity, Gamma, Hue, Saturation, Tint, etc.
- Animate any of the parameters
- Render it locally or Network render

Its not jet finish but I wanted to show some progress.

Jesus christ that's amazing! wow.

Every new feature had me popping my eyes out.
My boss has been gagging for something like that for ages after using Maxwell, but I wasn't too worried- but seeing this I think you could very well change the way we all work.

I look forward to trying it out!

Excellent work

Wow just wow.
Would love to have that for Mental Ray.
Keep up the amazing work.
  07 July 2008
Amazing! When it will be avaible...and how much? it's a great add to max. Thanks for this.

I started making something like this for use with fusion a while ago but never got around to finishing it. Your version takes it a step futher though. Great work.

This pretty much makes my
What are the render times for the scene in the video and all those lights?

  07 July 2008
Since you have to render the scene multiple times, once for each light(s group) it also multiplies the render times. Its almost your normal render time multiplied with the number of lights. Of course each time is slightly faster than normally since you only render one light at a time.

The only way to make this faster would be rebuild VRay render architecture to fully support it from the ground up.

, including new Gradient map for max:

I must have missed something,anybody getting sound on the video?

  07 July 2008
Thanks and yes I will add support for Mental Ray

Hopefully I can make it available next week.

The Render times depend on the file itself and the render settings which Iím not touching, as this changes from scene to scene, one thing that you have to keep in mind is that when rendering VrayMaterials only you will need much higher GI settings to get good quality.
As Bercon mentioned Iím rendering each group separately so yes it does take more time, two things you can do to help speed things up is to render over the network or use distributed rendering. But even if it takes longer you do have a lot of freedom with the result to play with the lights.
This can be used to final render, animated lights or just to see how the lights behave since its almost interactive.

In the Video, no it doesnít have audio, I made this video really quick to show how it works. I will be making another with audio.

Thanks for all the comments,

Hi Guillermo,

Very nice! This may be a silly question but, once you've played with adjusting your light values in your tool, is there a function to apply those settings to all the lights in the scene?


  07 July 2008

That would be something really good, but itís really hard as Iím tweaking an image (HDRI) not the actual light. There might be a way to average it but Iím not sure how to approach that jet.
