Camera System

A Depth of Field camera system with VR Friendly physical controls and a desktop mode

Quick Setup Guide

• Follow the general installation guide
• Import the PostProcessing package by clicking Window -> Package Manager in Unity and searching for PostProcessing
• Create an empty object in your scene where you want your camera to be spawned
• Click on Window -> UdonToolkit -> Camera System Setup in the unity top bar
• Drag and drop the created empty into the Camera Position field
• Provide a watermark overlay if you want to draw a watermark on top of the pictures people take, e.g. the world logo

The watermark should be a transparent 16:9 image (1920x1080)

• You can also add one of the default guide panels near the camera by checking "Add Camera Guide". This option is recommended, so your players know how to use the system
• Click Setup Layers
• Click Create Camera System
• Click on the created Camera Lens object and there Compile All Udon Sharp Programs at the bottom of the Udon Behaviour component
• You're done!
• If the positioning isn't exactly how you like it: Ctrl+Z, move the empty object and click Create Camera System again

Now you can build your project, and the camera should be working!

Usage and Examples

You are expected to use Camera System Setup UI from Window -> UdonToolkit -> Camera System Setup in the unity top bar to set everything up, consult the top of this page for the required steps. But here is a guide on the manual setup

• Drag and drop UT Camera System from UdonToolkit/Camera System folder into the scene
• Right click and click Unpack Prefab Completely (that is very important)
• Move out all the objects inside UT Camera System into the root of the scene (also important)
• By default camera is set up to use layer 27 for PostProcessing, and layer 28 for the VR Controls
• VR Controls layer is expected to be set to only collide with itself, otherwise you might get unwanted vr control interactions even if you did not actually press anything with your finger
• Make sure those exist or change them
  • You can set objects inside Camera Lens Profiles to any layer that is not PostProcessing or Default
  • Don't forget to update the target layer of the PostProcessing Layer component on the Camera Lens -> Lens Camera object
  • When using a custom VR Controls layer, make sure to change tha layer of Camera Left Finger, as well as the VR Controls and Start Sphere objects
  • If you changed the VR Controls layer - you'll also need to update it in each Sphere object's Area Trigger Collide With parameter
• Click Compile All UdonSharp Programs
• Check that every UdonBehaviour in the system shows set public variables: check Camera Lens, any of the VR Controls -> Sphere objects, Camera Tracker object, any of the Camera Flip, Always On, Focus and Switch Position objects
  • If any of them show No Public Variables - click Force Compile Script
• Click on the Camera Lens object and uncheck Is Active on the Parent Constraint
• Move the Camera Lens wherever you want
• Click Activate on the Parent Constraint
• Uncheck Is Active, expand Constraint Settings
• Uncheck Lock and set all the Position Offset and Rotation Offset values to 0, check Lock again
• Check Is Active
• You should now be ready to use the camera in your world!

This is a bit of an involved process, hence why the automated setup was created, the manual guide is provided for reference of what UdonToolkit is actually doing when you click Create Camera System
