Godot engine 3.2 rooms and portals module tutorial

Описание

This is a short tutorial for my simplified rewritten rooms and portals module for Godot Engine 3.2, it is now called 'cyclops'.

*Note* I am now writing a core version to be potentially included in the main Godot build. This will supercede cyclops, as this allows a far greater range of techniques compared to a third party module. However feel free to get started using cyclops in the meantime, the principles are the same and they should mostly be compatible.

Cyclops is specialised to baked light (lightmaps) only - ideal for first person shooters and similar games. If you need dynamic light support have a look at lportal, my previous version. Cyclops is intended to be easier to use, nearly everything can be done from the Godot editor UI, rather than script.

This video assumes an understanding of portals. For a beginner introduction to using portals for occlusion culling see this video:
