Using Positional Lights w Volumetric Light in MB3D by fraterchaos Using Positional Lights w Volumetric Light in MB3D by fraterchaos
Ok, I did this because I have found that while the other tutorials for Volumtric Lighting in MB3D are great, and absolutely necessary, they do not cover positional lights in any specific way, and I'd ended up explaining to one of my friends most of this in a less intelligible style via messages... so I felt that arranging it all in a more concise fashion might help some people who may have had trouble with Volumetric Positional Lights.

I do not claim to have all the answers, nor evewn that any of this info will actually work for you... every render is different, we all have a different style and a different way of working, and every fractal has it's own quirks!

As stated REPEATEDLY in the tut, you MUST already understand the basics of Volumetric Light to make use of the V Light portions of this tutorial... please see

for the basics about how to use V Light... I really can't stress this enough, you almost have to understand what these two show before trying to use my tutorial!

Also, for those just starting in MB3D, or anyone who is lost on things like setting dispaly vs. render sizes... Hal's first three MB3D tutorials are essentials too...

[link] and [link] and [link]

will help you with all the basics of using MB3D

I do hope this helps someone... feel free to download it if you want to study it in more depth.

Well written tutorial Charles - thanks for taking the time to do it!


I'm not up to V Lights yet - just tackling lights in general - but this was still helpful :D I'll revisit this several more times for sure as well as the tutorials you mentioned.

Thanks, fraterchaos, for the helpful tips on Positional lights.
You're right, the tutorials by bib and Hal are key to getting VL working; they're both good, but I still have some trouble with VL. I'm not blaming these two, my feel for lights and VL is not developed enough yet.
Anyway, another little tip I can pass along, is the use of the "Visible" dropdown just above the "mid" button.
When you click on the arrow, you can see a selection of values from 0-4, with higher numbers corresponding to a light spot of greater diameter. By making the PL visible, you can follow it as you move it with the sliders, until it is about where you want, then switch to the arrow "positioners". When you have the PL were yo want it, set the "Visible" setting back to "0" unless you want a spot of light for an effect.
Often when I have a PL light in a scene, I can't seem to tell where it is!, so I use the "visible" to turn the light into a spot, then I can find it on the screen, and move it accordingly, then turn it off by making "Visible" zero again.
Just a little tip that has helped me some, but I still need to work on getting better lighting effects.
Frac on, everyone!

yes, I usually do something similar, although I often leave the PL set to 4 and hide it behind some part of the fractal... I like the number 4 setting the best, it seems like it blends the light in better than 1-3

I'm glad my little tips helped!

Nice work and thanks for the mention Charles!

very welcome and thank you too!

(I sort of had to mention you and bib, because I didn't cover all the fog and depth issues that you explained, and people need to understand that before mine will do them much good!)
