Half-Life 2 - Unused Visgroups/Canals

d1_canals_01

Nothing significant.

d1_canals_01a

Nothing significant.

d1_canals_02

There are no user-defined visgroups.

d1_canals_03

Nothing significant.

d1_canals_05

After a significant period of trimmed maps, d1_canals_05 resumes the habit of leaving random bits behind, now conveniently placed into one group.

_panels

Four panels floating in the air. They likely were template brushes used while constructing the shantytown below.

_headcrabbing 1

A cut sequence involved in the shelling of this area.

_canister sound targets

Several info_target entities scattared across the refugee camp.

_button hudhint

An env_hudhint entity. It tells the player about a "MomentaryButton".

Ammo AI post idle

An additional logic_choreographed_scene entity.

Trivia

The unused visgroups are all subgroups of "unused".

d1_canals_06

_unrotated model pipes

An unrotated version of the nearby model pipe.

_second zombie cave

An entire cut section of the map. Unlike the name implies, however, it does not feature any zombies to fight. Considering the size of its entrance and the compatibility with the nearby player-travellable pipe, this was most likely the way that the cave would be accessed.

_brush_pipe

A brush-based version of the previously-mentioned model pipe.

_Tunnel Occluders

Several occluders.

Trivia

The unused visgroups are all subgroups of "Unused".
There is no "first zombie cave" visgroup mentioned.

d1_canals_07

_old blockade door

An unused prop_door_rotating, which was replaced by another. The differences between the two is that the unused version has the targetname "door_room5_blockade", alongside a few inputs, while the final has neither of those.

_dropship cop standoff

A ai_goal_standoff entity.

_grenade_puzzle

A cut sequence, involving a table set against the door. Judging by the surroundings, the player was to throw a grenade in in order to detonate the explosive barrel and move the table away from the door.

_gate stairs

Several nodes, and a set of stairs. Possibly unused because that set of stairs appears reachable by the player, while it is supposed to be merely a part of the scenery.

_old transition

An early version of the transition from d1_canals_07 to d1_canals_08. Among the differences are a set of brush-based "speed bumps", a overall lower height, and an earlier placement of the level transition trigger.

_Old manhack script

Four scripted_sequence entities. They were used to play the "wake up" animation of the manhacks, while in the final version they do this unassisted.

_shoot shelf seq

Another cut sequence, this time involving the shelves affixed fairly high up on the walls.

_01a tank

A slightly different version of the emplacement metrocop.

_old_env_fire_field

A fire field. The difference between the final version comes in on how it is done - in this version, it is with several env_fire entities. In the final version, it is done with an info_particle_system and several info_targets.

Trivia

This map partially breaks from the habit of placing every unused visgroup within a single visgroup, with the last three being outside of it.

d1_canals_08

_water debris

Several brush-based barges and miscellaneous debris props. The barges reference a missing texture present in the Leak - metalhull003b.

Similar barges also appear in the Leak's d1_canals_end, and were likely copied from that map.

_large pier

A larger version of the final pier, with numerous overlapping elements.

_debug ents

An "advance spawn" for the player, presumably for testing purposes.

_warehouse details

A hoisted-up stairwell.

_barge

A barge identical to the ones appearing in "_water debris", but alone.

_far pier cop

A sequence where a metrocop goes to the nearby dock. A fair amount of overlapping brushwork is included.

_extra nodes

Five unused nodes.

_lambda cache fences

Six fences, with occasional debris, placed above the playable area.

Trivia

This map resumes the habit of keeping all of the unused visgroups as subgroups of one visgroup, with eight being contained in total.

d1_canals_09

_09-10 trans

An early version of the transition between d1_canals_09 and d1_canals_10. It is exclusively brush-based, with the sludge ending shortly after the entrance.

_1 object

The arch used by 09-10 trans.

_Poles

Four sets of three lightpoles atop a bridge the player passes by.

trigger

A func_vehicleclip placed on the wall. Despite this being hidden, there is one on the adjacent wall that was not removed.

Trivia

This is the first map in the d1_canals series to completely lack a parent visgroup solely for removed visgroups.

d1_canals_10

_old transition

An early and far less detailed transition from d1_canals_10 to d1_canals_11. In addition to other differences, it lacks the "destroyed pipe" section, and is much smaller. Some bridge models are also included, seemingly by accident.

_old mega jump poles

Outside terrain
Inside terrain
Wireframe

Four models that were replaced by other props. They do not appear correctly, as they refer to a since-removed prop: "dock_bumper01d.mdl".

Trivia

d1_canals_10 has the smallest number of "Unused"-grouped visgroups, clocking in at only two.

d1_canals_11

_old exit tunnel

An early version of the transition tunnel to d1_canals_12. Unlike with the others, the player never enters it as the level transition takes place before it is entered.

_exit tunnel railings

A large number of railings on the exit tunnel. The final two towards the exit are kept, however.

_breakable piers

Two brush-based piers that are able to be broken. Strangely, the supports reference "MODELS/PROPS_DOCKS/DOCK01A" as their texture, which fails to display.
