For the needed script entries, see the vanilla BtB Venice script entry.

Puzzle Item 1: Nitrous Oxide Feeder
Can be attached to Motorbike for enhanced speed. It can either be picked up directly or combined out of:

Combo 1 - Valve Pipe (needs OCB 2 and a crowbar)
Combo 2 - Nitrous Oxide Cannister

Puzzle Item 7: Wires
OCB: 2
Lara needs the crowbar to pry the wires out of the fuse box. You can build the shatterable fuse box with DEBRIS 4 and SHATTER 2.

Puzzle Item 9: Card
Put -445 into the OCB of Puzzle Hole 9 so that Lara will use the correct animation.

Key Item 12
This bundle of keys can be used multiple times. Thus once instance of Key Item 12 can unlock infinitely many instances of Key Hole 12.

To create the full Element Puzzle you need:

1 Small Waterskin
1 Bottle of Wine (Pickup Item 1)
1 Bag of Sand/Earth/etc. (Pickup Item 2)
1 Torch to light the wine
1 shallow pool of water to fill the waterskin
1 Flame Emitter for Lara to light the torch
3 Element_Puzzle instances with different OCB settings, see below.

OCB 0 - Lara needs to pour in water from the waterskin
OCB 1 - Lara needs to pour in wine from the bottle and then lights it with the torch
OCB 2 - Lara needs to pour the content of the bag into the bowl

Place a heavy trigger underneath the element puzzle in order to trigger something when Lara does the appropriate action. You can use either use one, two or all three of the bowls. Please keep in mind though that Lara cannot carry more than one wine bottle or more than one bag of sand with her at once.

Warning!
If the player saves and reloads the game after pouring in the wine and before lighting it with a torch the wine disappears and the puzzle cannot be completed anymore. Make sure the torch and a flame are near the element puzzle to prevent this bug.
This bug will also be mentioned in the BtB readme for the players.

Door Type 5 is a crowbar door. Put 2 in the OCB so that Lara will open the broken wall panel with her crowbar.

Table (ARCHITECTURE_5)
Open the Objects menu and select Edit Object. Click on the + button twice to set the height of the table and click ok. Now Lara can climb onto the table in the game.

Fan (COG)
The fan needs to be placed with a separate collision object so that Lara can‘t walk through the fan. Use ROCK_0 as a collision.

DEATH_SLIDE
After Lara rides the slide you can reset it by simply placing a trigger for DEATH_SLIDE.

Rats (LITTLE_BEETLE)
To get a group of rats follow Lara simply add the number of rats to one of the following presets:
1000 - rats will come out of the floor
2000 - rats will come out of the wall
Example: to have 20 rats crawl out of the floor, simply enter 1020 in the OCB of the LITTLE_BEETLE object and trigger it.

Bat swarm (FISH)
Place the FISH object and enter the number of bats you want in the OCB. Trigger the FISH object to release the bats.

It is advisable that you base your script entry on this one. You are of course allowed to freely modify your script.
