LAMPLIGHT ALPHA VERSION

Lamplight is a studio plugin that can let you bake actual Global Illumination bounce lighting into your scenes.

Limitations:

  • Won’t work well in Future - use Shadowmap for best results
  • Not good for very finely-scaled scenes - roblox lighting is chunky!
  • No support for spotlights, coming soon
  • No support for surfacelights, coming soon
  • Really huge regions could take a while to light

Update v1.2

  • Massive performance improvements!
  • Now runs in studio mode correctly
  • You need to place Light Region objects to specify where to light
  • You need to click “Create Probes” manually now
  • Generated Lights are now attachments+pointlights

Update v1.1

  • Terrain supported, a few bug fixes

(place this model file in your plugins folder)

How does it work:
It places probes on a regular grid in the scene, where each probe is also a pointlight. It then does some trickery with a bunch of rays, sampling the scene and averaging the results.

How does it run:
Obviously baking is slow, but once it’s baked, it should actually be cheap to free, even on mobile.
Roblox is surprisingly awesome at having a whole bunch of pointlights when you’re not in Future lighting mode, and this takes full advantage of it.

Special thanks to Elttob for inspiring me to pick this back up, and helping me solve some of the problems I was having.

Please post screenshots if you get some nice results!


Update: If you are having trouble making this run, try enabling this feature in studio - seems to fix it.

I’m having some trouble opening this. Is this the correct location?

Thanks, after restarting Studio, it worked. I did not know Roblox automatically opens it for you.

Awesome idea for a plugin! Modifying the nodes during runtime will create some really cool effects.

It should be there once studio is open!

.rbxmx file? Might just be me but that sounds like an unsafe file?

Running some tests on free models…

As far as I know, that’s a file that is only used by Roblox Studio, so the worst that file can do is affect your game, not your computer.

You say future isn’t compatible with this, but what about shadowmap with PBR (SurfaceAppearance)?

Should be fine!

I tried testing this on the default village template, and it does not seem to be working.

  1. Everything is a point light

  2. I’m using shadow map.

  3. I’m playtesting.

Can confirm it’s not working on my end either.

Does the plugin require the user to start a test simulation or can it generate in studio?

Is there any way at this time to edit initial location of the nodes?

Seems like you spelled brightness wrong. :grin:

I cant get the plugin to work either. Tried it on a baseplate with some parts. The bake button thing actually did run, but all the probes it produced were black and all the lights had a brightness of 0 and were the default color.

Also, is there any reason why this plugin cant work in Run mode but only Play.

Hey, this looks really cool!
I made a fork of this that allows you to convert the baked parts into attachments and also clear your bake without having to re-bake everything

An rbxm/rbxmx file refers to the Roblox Model format. The x at the end determines whether the model is encoded in XML or binary.

Nice, I’ll add those to the main branch shortly.
