I create LOD on some models to reduce the number of vertices depending distance visibility:
Original > Lod1 > Lod2 ...

urban_tree_giant01_a : 7632 > 2960 > 2700 >2200
sapin1_lg : 2189 > 1686 > 939 > 622 > 482 > 414
cedar_large01 : 2391> 1808 > 948

pont_bailey_1 : 384 > 164
pont_bailey_2 : 588 > 240
pont_bailey_3 : 528 > 320
pont_bailey_4_physique : 656 > 404
pont_bailey_4_impact : 996 > 408
pont_bailey_4_impact_physique : 660 > 404
pont_bailey_6 : 1530 > 560
pont_bailey_8 : 1168 > 714
pont_bailey_12 : 1680 > 1024
pont_bailey_16 : 3360 > 1204
pont_bailey_debut : 592 > 244
pont_bailey_fin : 519 > 202
pont_bailey_trou : 816 > 450

• Reduce Light indices on displacement
  
• remove light error due to the skybox shadows on prop_door_rotating

• Change The keys (5 and 8) on the crane... i don't know what keys to put.
  
• Change the destructible part of the tower, when it's dropping that will disappear.
  
• Change the destructible part of bridges, i want to put a decal to see where you can put C4 or big damage (chirurgical system attack).

• Add many info_lighting on some static props

• new spawn area with helicopters (for battleroyale gameplay)
  
• Admin Room to control some systems (npc, remove helicopters...)
  
• nodes for AI into buildings

• In the admin room, i will create a button to spawn buttons on bases to open garage doors (for Rp players..)

• Make an alarm system when a bomb is falling down on one base.
  
• Create a complex NPC system to create relation ship between teams
  
• Create player/npc M60 turret on each bases.

• Credits...
  
• An easter egg :)
