Could anybody make a glow ball using 3ds MAX? I can find only it for Maya

Hi,

I am trying to make a glow ball, but cannot find any tutorial for 3ds MAX.

Could any body do it and upload an example?

Thank you in advance.

What's a glow ball? Is that a mesh light?

You could also try using Emission.

This is what I meant. Emission won't be enough to give the surrounding effect

We can exploit the fact that volume materials are mediums and so, if light is calibrated in them in confined spaces and clamped, they will glow.

Try these settings as a start point on a volume material you put on a object offset from your geometry you want to give light into the surrounding atmosphere. You set the actual light spheres material to some emmission to control its visual look, and you make an Arnold light and assign the mesh so the mesh becomes a light, you need both to get surface blowout and atmosphere bleed.

You need to adjust several parameters on the volume material until you get the right clamped look you are after, technically it will work fine.

You can make it as big or small as you like, just make sure to clamp before you reach max radius, else the edge will show.

I attached a max 2019 file you can inspect.

Hi Mad's,

I'm unable to open your example because I don't have 2019. I've attempted to recreate this but nothing will pass through my volume material (it's completely black). Any idea where I'm going wrong? Banging my head against the wall :s

Hello @Mads,
(I am newbie) I am looking for a solution to create a similar effect but without blowout from the object, only atmosphere blend.
Here is my problem:
test.jpg
as you can see I want to create green glow around gold objects. But using Arnold light mesh to gold objects (+arnold light decay) and creating new bigger (offset) object around them with volume (scattering is green), is giving me this, which is ok on black background but bad on brigther one as you can see those darker contour. How can I avoid those darker contours, I assume they are due to transparency of volume object cannot be absolute. I am using 2 additional lights but excluding them doesnt work.

- is there a way how to make object invisible for selected light sources (because I want the volume object to interact only with mesh light)?
I also tried emmision approach which didnt work, because it give me edges. And I couldnt find any simple way how to map opacity using gradient from the faces, for example?

Thank you in advance.

Have you tried the bloom imager? It might give you some more control over the effect.

thank you for reply. However, I dont think it will works for me.
I am using proposed approach with mesh light on object inside of volume object. However, I dont want the bigger volume object interact with any other lights, because then I can see those darker areas. I am attaching simple example (image and 3dsmax19 file) of described situation. I used ligth decay to less then half of big sphere, so the outside blue shere edges can be seen, then inside is confined mesh light. volume_object_decay.zipvolume-object-decay.jpg
What I want is something (simple) like this image2365.png.
Also, I am not sure if I am asking on the right place.
