# godot-lportal
|
|
Portal rendering / Occlusion culling module for Godot 3.2\
|
|
|
|
You can either use LPortal as a full occlusion culling system if you can create your level as rooms and portals, or use it in a simplified single room mode to speed up culling in any 3d level.
|
|
|
|
Note that this is a _Work in progress_. It is recommended to wait for a first release.

## Current status
|
|
The first demo tutorial (see above) is now working with the internal godot baked lightmap workflow. It shows registering dynamic objects (DOBs), loading and unloading levels.
|
|
|
|
Dynamic lights are now working, both global (directional lights) and local (omnis and spotlights):\

|
I have just added a single room mode, which allows LPortal to speed up culling in games that haven't even been designed as rooms and portals.

## Installation
|
|
You will need to compile Godot from source (for now). See:
|
|
http://docs.godotengine.org/en/3.0/development/compiling/index.html
|
|
|
|
Once the engine is compiling okay on your system, to add the module:
|
|
* Create a folder inside godot/modules called 'lportal'
|
|
* Clone / download this repository as a zip file and place the files in the lportal folder
|
|
* Compile the engine as normal, it should automatically pick up the lportal module
|
|
* Note that to export to other platforms you will also have to compile export templates for those platforms
|
|
|
|
You will know the installation was successful when you see a new Node type 'LRoomManager' in the Godot IDE.
