Serif Mixology Start Guide

Introduction

Serif Mixology is a cocktail system you can place in your VRChat world. You can reproduce authentic bar actions, such as pouring from bottles, adding ice and shaking in a shaker, or skip steps and make a drink quickly. It is up to you.

Editions and the two versions

Serif Mixology has two versions that differ in how you pour (the optic version and the hand-pour version). Which versions are included depends on the edition.

The packages inside are SerifMixology_FullSuite_v1.x.unitypackage for Full Suite and SerifMixology_Standard_v1.x.unitypackage for Standard (x is the version number). Standard is Full Suite without the hand-pour prefab and without the materials and spout models used only by the hand-pour version. All other files are the same (if you import Full Suite over Standard, they are treated as the same files).

Parts of this guide marked Full Suite only describe the hand-pour version. Standard does not include it.

Differences between the two versions

The two versions differ only in the liquor bottles (24 bottles). The other equipment, such as the syrup rail, wine dispenser, bitters and soda gun, is the same in both versions. The inner mechanism is the same too, and the ingredients on the shelf are always the same (ingredients you change in the wizard apply to both). With Full Suite, you can also place both versions in the same world.

Both versions include a soda gun (15 kinds of soda and juice), the syrup rail, the wine stand, bitters, garnishes, an ice machine, a sink, a shaker, a mixing glass, salt and sugar for the glass rim, a glass dispenser, and the bartender's tablet (→ Equipment list (Japanese)).

Guest menu

SerifMixology_Menu is a menu tablet that guests can only look at (its body is champagne gold, so you can tell it from the bartender's tablet). It is a separate prefab from the sets, and you can place as many as you like on counters and tables. For details, see The guest menu.

Requirements

• Unity: 2022.3.22f1 (the version VRChat specifies)

About support

What support covers

Modifying the product is free for you to do (→ Terms of Use). But we cannot try your modified state in the same way on our side, so we have to treat it as not supported.

When you report a problem

If you include the following, we can find the cause faster.

• The product version (example: v1.0)
• VR or desktop
• How many people were in the instance, and whether you were the master (the first person who joined)
• Whether it was right after entering the world (right after joining late)
• What you did just before it happened
• Whether the same thing happens in the sample scene

Contact

For support such as usage questions and bug reports, please use the official Serif Discord (https://discord.gg/E5b6FhfMCg).

For questions about the license or contact about corporate use, you can use Discord, or you can send a message from the BOOTH product page.

💡 For general Unity questions, asking an AI such as ChatGPT is often a quick way to get an answer. Feel free to try it.

From setup to placement

This chapter explains, in order, how to place Serif Mixology in your world and get it working. There are 6 steps.

Step by Step — Follow the steps in order

1

Prepare a world project

Serif Mixology is something you place in a world. First, prepare the world project where you will place it.

• If you will place it in a world you are building now — You can use that project as it is. Back up the project before you start.
• If you want to try it on its own first — In VCC, choose 2022 World Project from Create New Project and create a new project.

On the Manage Project screen, check that VRChat SDK - Worlds is up to date.

2

Import the product

Open the project in Unity, and from Assets > Import Package > Custom Package..., load the .unitypackage of the edition you bought (SerifMixology_FullSuite_v1.x.unitypackage or SerifMixology_Standard_v1.x.unitypackage). Leave all items checked and press Import.

When the import finishes, scripts start compiling. Wait until the loading indicator at the bottom right of the screen stops.

The product is imported into Assets/Serif/SerifMixology/. Your own recipes and ingredients made in the wizard will be created later in Assets/Serif/_UserData/ (→ Included prefabs and folders (Japanese)).

3

Place a set

Open your world's scene, and drag the prefab you want from Assets/Serif/SerifMixology/Prefabs/ into the scene.

• SerifMixology_Optic — the optic version (measure and pour from the bottles on the shelf)
• SerifMixology_HandPour — the hand-pour version (pour by holding the bottle) Full Suite only
• SerifMixology_Menu — the guest menu (a look-only tablet; as many as you like; place it together with a set)

Placement tip: drop it straight onto the counter top

The origin of a set is at the position of the garnish tray, at the height of the counter top. In the Scene view, point the mouse at the counter top (a surface with a collider), around where you want the garnishes, and drop it. Then the things that sit on the counter top (garnishes, the syrup rail and so on) land exactly at the counter-top height.

The origin of a set is roughly around the garnish tray, at the counter-top height (the screenshot is the sample scene)

The standard layout assumes a bar where the aisle between the front counter (optics, syrups, garnishes, sink and so on) and the back bar behind it (wine, mixing glass, glass dispenser and so on) is 1.3 m. Move the equipment one by one to fit your bar (→ Moving equipment (Japanese)). The optic version's shelf hangs from the ceiling, and the distance to the ceiling can be adjusted in the Inspector (→ Mounting the optics (Japanese)).

4

Run 「全セットを登録」 (Register all sets)

After placing, run the menu Serif ▸ Serif Mixology ▸ 全セットを登録 (Register all sets). This creates the glass numbers and the equipment list, and connects the sets in the world to each other.

Run 「全セットを登録」 (Register all sets) again each time in these cases:

• When you place (add) a set or a guest menu
• When you duplicate equipment or glasses

It is also registered automatically when you press 「適用」 (Apply) in the wizard. Even if you forget, a check appears before upload and stops it, so a broken world will not be published as it is.

If you forgot to register, this check appears before upload. Press 「登録して続ける」 (Register and continue), and the sets are registered

When you want to change recipes or ingredients, open the menu Serif ▸ Serif Mixology ▸ カクテル・ウィザード (Cocktail Wizard), make your changes, and then press 「適用」 (Apply) at the bottom of the window. At first, you can leave everything as it is (→ Cocktail Wizard (Japanese)).

5

Set up lighting

It works without them, but placing the following two makes liquids and glasses look much nicer. They do different jobs, so ideally you have both.

① Reflection Probe (reflections)

Place one Reflection Probe near the bar, turn Box Projection on, and fit the box to the size of the room. The surroundings are faintly reflected on the rims of glasses and liquids.

If there is none, the Environment Reflections (sky) in Lighting are reflected, so the rims pick up a faint sky color (with a blue sky indoors, the rims look slightly bluish-white).

② Light Probe (brightness)

In a room where you bake lights, place a Light Probe Group around the bar (at the height where you move while holding glasses) first, and then bake. Without it, the glasses and bottles in your hand do not match the room's brightness, and they look too dark (or too bright) and out of place.

An example with a Light Probe Group placed (the screenshot is from another product's demo world)

Liquids are lit by ambient light, Light Probes and one directional light. Real-time point lights and spot lights do not affect liquids (they do affect the bodies of the glasses and bottles).

6

Upload, and try it in VR

Save the scene and, as usual, run Build & Publish from the Builder tab of VRChat SDK > Show Control Panel. Check that the build target is Windows (PC).

A check runs automatically before upload. If there is a problem you could not notice until you enter the world, such as forgetting 「全セットを登録」 (Register all sets), it stops here. When it stops, the reason is shown in the Console, so follow it to fix the problem (most cases are fixed by 「全セットを登録」).

Once the upload is done, go into the world in VR and make one drink. We recommend choosing a Highball from the 「定番」 (Classics) tab on the tablet and following the lit parts in order. Good work!

Using it in the world

Controls at a glance

The set seen from the bartender's side

The tablet

On the bartender's tablet, you choose the recipe to make. When you choose one, the steps are shown, and the lamps of the equipment you will use light up.

• 定番 (Classics) — 12 common drinks (ハイボール (Highball), ジントニック (Gin & Tonic), モスコミュール (Moscow Mule), ブルーハワイ (Blue Hawaii), カルーアミルク (Kahlua Milk), テキーラサンライズ (Tequila Sunrise), モヒート (Mojito), ギムレット (Gimlet), ネグローニ (Negroni), オールドファッションド (Old Fashioned), キールロワイヤル (Kir Royale), ドライマティーニ (Dry Martini))
• 名前から (By name) and ベースから (By base spirit) — You can look through all recipes in order of name, or by base spirit
• Custom tabs — You can make and show tabs that collect only the recipes you choose, such as your shop's menu (→ Standard and custom tabs (Japanese))

When you enter the world, the 「はじめての方へ」 (For first-time users) guide is shown. Tap the board to close it, and the 「はじめての方へ」 button at the bottom left of the list brings it back.

The tablet's three buttons:

• Auto Match — Even if you make a drink without choosing a recipe, if it matches any recipe, it gets the finished look. It starts ON for everyone, and looks the same to everyone (if you turn it OFF, only the screen of the person who pressed it stops showing the finished look)
• 若葉 (beginner leaf) — Show or hide the name tags on bottles and so on
• 鍵 (key) — Beginner assist. Only things lit by the guide are accepted (you can use it only while a recipe is chosen)

Name tags shown with the 若葉 (beginner leaf) button

When you go off the recipe, the tablet shows 「自由な一杯として続けられます」 (You can continue it as a free-style drink). If you want to start over and follow the order, empty the container in the sink and then choose the recipe again.

When you choose a recipe, the steps are shown

The 「はじめての方へ」 (For first-time users) guide shown when you enter the world

The guide lamps

When you choose a recipe, the lamps of the bottles and tools to use next light up (only the person who chose the recipe sees them lit).

• Orange — 2 or more times left
• Yellow — 1 time left
• White — while pouring (while the glass is pressed against an optic), and for a moment when everything to be added from that equipment has been added

Left = orange (2 or more times left) / Right = yellow (1 time left)

Glasses, sink and the ↻ buttons

One glass at a time appears at each spot of the glass dispenser, and when you take one, the next appears. However, the number of glasses is limited. If a spot stays empty, all glasses of that type are in use (it is not broken). A glass you empty in the sink goes back to standby, and comes out again when a spot is free. If you run short, the world's creator can increase the number in the wizard (→ Number of glasses (Japanese)).

The reach of the buttons you press (return, recall all, the wine pour button, the optic height switch) is 0.3 m. In VR it is measured from your hand, so you can press it by bringing your hand close. On desktop it is measured from your eyes (viewpoint), so you cannot reach it unless you move close.

Left = coral ↻ (recall all) / Middle = green ↻ on the bar mat / Right = ↻ at the back of the tablet stand

The soda gun

When you hold the soda gun, a list of drinks appears above the gun (only the person holding it can see it).

• VR: choose with the right stick, up and down
• Desktop: choose with the mouse wheel, or with ↑↓ (PageUp / PageDown also work)

You can pour only while you hold Use (the trigger). While a recipe is being guided, when that ingredient reaches the recipe's amount, it stops by itself even if you keep holding (it is not broken). As the tablet's 「はじめての方へ」 (For first-time users) guide also says, soda water and juices come from the soda gun.

When you hold it, the list appears above the gun (only the person holding it can see it)

The guest menu

This is a tablet for guests to look at the menu. The list is the same as the bartender's (Classics, By name, By base spirit, custom tabs), but it is only for looking at the menu, and you cannot choose a drink (no steps are shown either). Each viewer can operate it separately, so any number of people can look at it. You can also pick it up, and return it with the ↻ on the stand.
