  1. Creating Big Ass Levels Zones, Portals and Anti-Portals and Volumes

  2. Zones • Air-tight areas of your level that constitute different areas.

  3. Portals • These are the windows between your Zones • You can either think of zones as airtight areas, or pretend to fill them with water

  4. Occlusion Planes (Anti-Portals) • Either a plane, or a BSP brush • Terrain is Occluded in 16pixel Chunks • BSPs on a perPolygon Basis • Static Meshes on a Per-Mesh basis • If a player gets inside the Occlusion zone the Hall of Mirrors will come visiting http://wiki.beyondunreal.com/File:Legacy_antiportal-occlusion-diagram.png

  5. RMODE 1 2 3 and 4 • This is your console friend to view zones and portals • Well not exactly.... • The BSP brushes are coloured using different colours for each zone. • You just have to guess where the portals are based on this • Demo: AS-Convoy

  6. The benefits of Zones • Zone Specific Reverberation • Render Speed • Level Complexity

  7. Bad Portals.... • There are two problems you are likely to encounter with poor portals • Zones not separating • You can check this with the Zone/Portal view in UnrealEd or RMODE 2 ingame. • The Hall of Mirrors • If your portal is recognized by the Engine, but players can see around it, they may look off towards infinity. • wm_textures.Editor.ZonePortal

  8. Creating Portals • There are 2 tools required to create Portals • The Sheet Brush Tool • The Special Brush Builder • The smaller the portal, the faster the processing of it

  9. Using your Portals In UT toadd specific properties to your zones, you needed to use ZoneInfoactors In UT2003+ Zoning has been detached from Volumes, so Zones are simply for Object Rendering (and skyzones still!)

  10. Zone Specific Iterators ZoneActors (class<Actor> BaseClass, out ActorActor)  Iterates through all actors in this zone. LinkToSkybox ( ) [simulated]  ActorEntered (Actor Other)  ActorLeaving (Actor Other) 

  11. Creating Anti Portals • This is the same as creating a Portal • Do NOT let the player see the Anti-Portal = BAD

  12. Volumes • There are many uses of Volumes • The most common are Physics, Water, Blocking and Ladder Volumes • There are many more, but you can go for a code browsing journey to find out what they do

  13. The End Almost.... And now for some console commands!!!
