Dynamic lights shining through solid 3D floors...

They definitely are blocked by regular one-sided walls. Creates some awesome shadow effects.

Hey all,

So... got some attenuated dynamic lights on the ceiling of a 2nd floor building with a 3D sector separating the two floors. The dynamic lights are illuminating through the 3D sector.

Any way to fix this? Is there a minimum thickness to a 3D floor that blocks the dynamic light? Or is it just one of those "it's just how they work" things?

Cheers for any help on this.

Upon testing this the solution appears to be adjusting the intensity of the light so that it will not shine through the floor.

This may require additional lights at the same height to offset a single light's intensity on the floor you want it to appear.

Best of luck with your project!

Dynamic lights are blocked by 1-sided lines if "light shadowmaps" is enabled, otherwise light will go straight through them (just like through 2-sided lines or 3D floors).

I've tried everything... backing off the intensity of the light only dims it in the upper area where I need it bright.

As boris already mentioned: See Options - Light Shadowmap

addendum

play with the light intensity and height

You may want to try changing the Brightness of the 3D floor control sector.

The described method, while requiring additional light things achieves the effect I believe you're going for.

*Screenshots do not reflect the initial test map:
Added additional lights, lowered brightness of all sectors to 128.

Last 2 screenshots I raised the 3D floor to show that the lights do not shine through the bottom of the 3D floor.

No additional settings required.

As far as I know, there is no way to prevent this. Dynamic lights bleed through doors and other two-sided lines, and I expect them to do the same with 3D sectors. The only things that stops them, other than distance, are one-sided lines.

Yeah, that was what I suspected... I can adapt the map to make use of it.

Cheers.
