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.
“ssigned a volume material to the cube, assigned the volume material within render settings ‘scene environment’ tab”
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.
