Cool, that looks like a decent rendering already. – Also the Cycles image required some color and contrast adjustments. Putting this through the compositor or Photoshop should lead to a great rendering as it is. It´s only a shame, that the emitter material is not working in Eeevee, but in this scene it is only the backlight plane, that needs to be replaced with an area light luckily.
It’s a hack, but it “works”. I clipped the alpha on the caster (to hide it), but kept the shadow alpha of the object on hashed. I then have the volume with the same noise and edge settings. Right now it’s a spherical volume..
@davis, it looks like the Eevee volumes can’t cast a volume inside geometry other than the bounds, so I have to… hack them. I am figuring out how to do it now.. either make some cool noise looking clouds in bounds to your artistic style or make a system that can… do things like this spherical edge projection system I’m working on.
Lately I’ve been busy working on proposals, investing hours into “sales” to win a client with a showcase of what I can do for them. Most of the time it works – and so far… it helps a lot. But it takes some personal investment to do.
