Volumetric Lighting

[c4d019]

Hello,

I'm having trouble setting up a volumetric lighting effect.

I've created a cube, put the corona camera outside the cube, assigned a volume material to the cube, assigned the volume material within render settings 'scene environment' tab, created a corona light inside the cube and not getting anything.

Can the volumetric effect be used with a standard cinema 4d spot light?

All I want to created is a volumetric spot light effect.

Developers, is it too much to ask for a volumetric light checkbox within a corona light?

Decay or falloff on a corona light would also be useful like vray.

Thanks

Here's a scene you can study. Adding a checkbox isn't really how light works in real life. No light is volumetric, it comes from its surroundings ;)

You don't need to do both - either a cube with a volume material applied, OR an environment override for a volume material, will do the trick. Not sure what both together would do :) The env override is usually best, unless you specifically want to constrain the effect in some way (only certain lights / only certain parts of the scene / ground fog / etc.)

Thank you beanzvision, will play around with this. I like the fact that you can use volumetric in conjunction with IES but my first impression was that is was a little slow to render.

Thanks for your input, I would definitely want to constrain certain lights as the majority of my work uses a lot of ground lights and spot lights from above with a volumetric effect shining down - all depending on the style that I'm looking to achieve.

I've already said it above and I understand and can appreciate the explanation that beanzvision gave above that in real life no light is volumetric however in this case a simple checkbox within the light dialog box to ignore or include a volumetric effect would come in handy, instead of having to create geometry around a light apply a material to it seems not the best way achieve or control the effect, for instance could the material be applied to the actual light instead of geometry surrounding the light.

I say this coming from being so accustomed to using c4d's lights and how its volumetric properties are controlled within the actual light, just seems more straight forward.
