✨ About LTCGI
LTCGI is an optimized plug-and-play realtime area light solution using the linearly transformed cosine algorithm for standalone Unity and VRChat. Free to use with attribution. It can utilize the Unity build-in lightmapper or Bakery for realistic shadows on static objects.
LTCGI is distributed freely under a mixed-MIT license. For more details, checkout the LICENSE file.
The 'Getting Started' row on the left is a good place to start reading. Follow the numbers! (🔢)
I also recommend reading at least the Performance Optimization section from the Advanced row.
About this Page
This site is the official documentation for using LTCGI-based lighting in your projects and worlds. It covers everything you should know before using LTCGI. I highly recommend skimming all the pages at least once to gain a basic understanding of what journey you're about to embark on.
⚠️ I've tried to keep things simple, but do note that LTCGI is an advanced lighting solution. If this is your first time touching Unity, this may simply not be for you - stuff will break, any you will need to read error messages and troubleshoot things.
Read the FAQ before asking for help anywhere!
Once you've done that, feel free to join my Discord and ask for help: https://discord.gg/r38vJd2DuJ
⚠️ NOTE: While the shader is optimized, it still equates to real-time lighting - so use sparingly, and read these docs carefully for tips on performance! Often times a reflection probe or a simple realtime light are the better solutions!
