View Full Version : LW2018 volumetrics & caustics?

So I know the (proper) caustics are about as ever in LW, but will the GI-based "caustics" plus volumetrics generate optical effects like halos* around bright light sources (in fog)? Or do such effects need to "faked up" in LW2018?

I'm constructing a test case, and guessing I'll need to fake it up for same reason lens flares must be faked, but also seemed worth asking.

*: Atmospheric halos are similar to but slightly different from lens flares (it's essentially the light acting upon the atmosphere itself as if a lens element). 22-degree halos (https://en.wikipedia.org/wiki/22%C2%B0_halo) around sun/moon are a well-known example.
