Is there any way to add fake shadows when dealing with Popcorn FX light

This torchlight doesn't cast shadows. I can live with the lack of shadows for the chairs, but not beneath the crucible. Is there any way to stop the light beneath the torch from going through the bowl and lighting the floor right beneath it?

Hello, jjdigitalgraphics here is one method you can use to create a shadow add a spot shadow this works well particle.

I thought about that, but I figured that the light that was seeping through the bowl would just fill the shadow and that the light outside the shadow would be doubly bright. I'll give it a shot.

BTW, there is a way to do this in DAZ by disabling limits and making the light power negative. The light sources become shadow sources. A sot in key places could create the needed faux shadows.

Here is a different method, in this example, using the torch fire I have set the light intensity to zero for the particle effect and added a spotlight to get the shadows and flickering effect by keyframing the transform and intensity and color over time, I've also added a custom shader to the inside of crucible to create the heat effect there is a version with, GI on and off I hope this helps.



I hope this helps.

You can lower the light intensity, and also disable GI for the sparks and fire in the resource list.

One more tip.
By default a single shadow caster has quite weak shadow, even if darkness is cranked all the way up (specially for night scenes).
To get naturally looking dark shadow you may want to stack them up. Keep duplicating them up until shadow is dark enough.
(just tweak spacing between them as stacking can cause shadow artifacts on the ground - a z-fight)
You may also attach all casters to some dummy for easy management.

Here I have a *pyramid* of 5 spot shadow casters:

as oppose to a single caster, which leaks a lot of lights:

OMG! I have never noticed shadowasters

Actually Kevin in his first reply suggested spot Shadow caster ;)
I just do not like how single caster works and figured multiplying would help along to amplify shadows.
