Darken an area

[snatcher]

Weird, I know.

Think of a magic light-absorbing / light-bending portable item of some kind that darkens the area it is in. Can you think of any trick to artificially darken a spot dynamically?

Lights can be controlled via script. You could use setLightParms :

Thanks, nbohr1more.

We can create light sources on the fly: shoot a projectile, bang, lit up an area for limited time. I wonder if we can create an anti-light source in a similar way, to temporally darken a corner in example. Crazy stuff.

I am not yet familiar with setLightParms. I have so far been trying to understand how ambient_world, location_settings and info_location work.

Before I start wasting my time, do you, experienced people, think anything convincing could be achieved?

This exact behaviour can be created using a blendLight using the blend filter blend mode.

The light becomes a volume which simply multiplies (darkens) its projected texture with the texture of contained objects, almost like a 3D volumetric decal.

Impressive, OrbWeaver. Thank you very much.

Blend lights have the least performance impact. Blend lights can also be used to create "negative light".
