Prism Lighting Engine (1.1.4c) - A Light Baking Plugin | Future Lighting Update | Global Illumination, Godrays


Prism Lighting Engine

Building better graphics

What is PLE?

PLE (Prism Lighting Engine) is a light baking plugin created for enhancing your games graphics through a variety of features. The main ones being Indirect Illumination and Volumetric Lighting.

How do I use PLE?

To use PLE, open up the baking GUI, you will see this GUI:

Now, select a light, and customize to your liking. After customizing, click Bake Lights. To clear ALL lighting, click Clear Lighting.

What are PLE's setbacks?

At the moment, PLE only supports baked lighting, pointlight and spotlight instances. PLE only works well with ShadowMap, Voxel, and Compatibility

Where can I get PLE?

Currently, PLE is available for 600 Robux on its page in the Creator Store.
You can get it here

Fixed Length Effects being a Incrementor!

1.2 comes out within the next week. It’ll come with a revamped light engine and along with it, better shadows!

A early access version will be accessible in version 1.1.5


This is the most beautiful thing I have ever seen, sure even if you have 50 dollars volumika is great, but this tool is baked meaning it’s probably more performant and works better for static scenes, also the global lighting looks incredible.

I’m excited for what else this project has to offer in the future.


will a demo place be available?


Probably with update 1.1.5 or 1.2

Suggestion to have the values for the settings in the plugin save for when you reopen studio.
(plugin:SetSetting(key, value), plugin:GetSetting(key))
It would make it a lot easier for developers to have specific looks to their game without having to remember their settings, especially as you add more features.

You should also consider adding more settings for the various things, like adjusting godray intensity, and changing what determines a reflection for indirect lighting (for different materials, etc.), and cleaning up unnecessary folders created by the plugin.
