ProTV Troubleshooting and FAQ

This page will contain various common issues and related solutions for getting ProTV to work how you want it to. This page will expand as time goes on.

How do I view the logs?​

SOLUTION: The logs for VRChat are located in the APPDATA folder on windows %APPDATA%\\LocalLow\\VRChat\\VRChat\\*.log. Sort by date modified to get the latest log file.

Though the better solution is to make use of U#'s log reader tooling by first enabling the debug log and UDON log flags --enable-debug-gui --enable-udon-debug-logging (pics 1 & 2 for reference) and then enable the U# log reader in the unity editor under the Edit->Project Settings menu (pic 3 for reference).

How do I make the TV's audio global and not spatialized?​

SOLUTION: On the speaker game object, remove the VRCSpacialAudioSource component. Uncheck spatialize on the AudioSource if it's there, then remove any keyframes from the curve if there are any for spacial blend (only required if the spatial blend value says 'controlled by curves'), then set the spatial blend slider to 2D.

I'm getting errors about IsValid missing the Utilities namespace.​

SOLUTION: VRCSDK menu -> Reload SDK If that doesn't work, keep doing it, restart Unity, mix the two. If you've done dozens of times and it's still not working, make a new project and migrate your assets.

Welcome to unity development.

I keep getting an error about 'ProTVBuildHelpers' failing.​

SOLUTION: Examine the build checks log via Tools/ProTV/Open Build Checks Window. It should detail any issues that need resolving.

I bought a world that came with ProTV, but nothing is working​

SOLUTION: The world was likely poorly exported and did not properly include all necessary dependencies, thus breaking references. It is recommended to import the latest ProTV 3.0 beta. This will remove any older version that may be in the world.
Read the 3.x Migration Doc to get started.

I imported a playlist with a lot of entries. My world size is now much bigger. Is there a way to reduce the world-size without losing any entries?​

SOLUTION: In C#, strings/urls are encoded in 16bit character arrays. This means that each character in a URL is 2 bytes. If you want to keep all the entries and reduce the world size, you will generally want to shorten the URL lengths.

Here's an example set of numbers: Given 800k entries (an extreme example), if we remove 10 characters off of each url... the world size would be decreased by almost 16 MB. 10 chars * 2 bytes * 800,000 entries = 16 million raw bytes removed / 1024 = 15625 KB / 1024 = 15.25 MB

Same goes for alternate URLs/titles/tags. The more data you have on each entry the more the world size adds up. Simple math. You need to determine your choice of balance between world size and desired data available.

Or

SOLUTION: For ProTV 3, when connecting the AudioAdapter, new AVPro speakers will typically be created to facilitate good audiolink reactivity. If that doesn't work for you, the easiest way to do it manually is the following steps:

  • (For AVPro) Make a copy of one of the audio sources
  • Remove the VRCSpacialAudioSource component
  • Uncheck spatialize on the audio source if it's enabled
  • Set the AudioSource Spatial Blend to 2D (aka value 0)
  • Set the volume to 0.002
  • Set VRCAVProVideoSpeaker Mode to StereoMix
  • Set Stereo Pan on AudioSource to the middle (aka value 0)

The TV works, but I can't input any URLs in the UI​

And/Or

The media controls prefabs are missing the Main URL object​

And/Or

The script on the MediaInput game object is missing​

This is due to a Unity import bug related to the SDK itself (Thanks Unity).

ProTV 3.x Users

This issue should be resolved 99% of the time by running the build script via menu Tools -> ProTV -> Update Scene.
Try that first, and if that doesn't work, try the below steps.

SOLUTION: Remove ProTV from the assets and scene. Save/close/reopen the project. Go to the VRChat SDK unity menu and select Reload SDK. Save/close/reopen the project. Then reimport ProTV into the project.

If that doesn't work, try the following alternate sequence that some have found to work: Remove ProTV from the scene. Save/close the project. Go to the project's assets folder in your file explorer and delete the ProTV folder manually. Reopen the project and go to the VRChat SDK unity menu and select Reload SDK. Save/close/reopen the project. Then reimport ProTV into the project.

If that still doesn't work, you'll need to manually reconnect all the references. (See pictures) When the VRCUrlInputField breaks, certain references are lost. Below (pic 1) points out what you need to reconnect (certain prefabs may differ from the picture, same process is needed though). Yellow is the object references and green is the events you need to re-add. Once that's done, you'll then need to reconnect the VRCUrlInputField back up to the controls (pic 2).

The TV reference is being removed from the Playlist plugin component​

SOLUTION: Unpack the playlist prefab. Unity likes the break that prefab for ProTV 2.x. This is not an issue in ProTV 3.x.

REASON: (This is one of multiple reasons why a youtube link may fail to resolve part of the time) Links that are generated through a youtube-dl service (eg. nextnex, thetechnolus, vroxy) are tied to a particular country/legal jurisdiction, but are generally transferable between regions, meaning that I can generate the link on a server in Germany and open it on a client in the US for example. But as soon as the video is region-locked in any country, the links are generally no longer region-transferable. So if you have a video that is only blocked in Russia, you might not be able to transfer the link from Germany to the US, causing a 403.

The loading bar on the TV is getting stuck at the end. What's going on?​

REASON: The loading bar is technically just an animation. There's no way to know what the progress actually is for a url request.

If you are in VRChat directly and it gets stuck at the end, that means either the script has crashed or it's taking a long time to resolve. I have observed many times where a youtube video is taking excessive time to load (more than 30 seconds), but eventually it does either load or fail which will then disable the fake animation.

If you are trying to play it in editor via ClientSim, that likely means that it's trying to load a url into a video player component that doesn't exist causing the script to crash. To avoid this you will need to include the ArchiTech.VideoPlayerShim package into your project.

Is there a way to load in a playlist from an external hosting source like pastebin or github?​

ANSWER: URLs cannot be created dynamically during runtime. This includes from a JSON response. VRCUrls can only be created during world build-time or manually entered into a VRCUrlInputField by a user in-game.

Is anyone having an issue where the VRCAVProVideoScreen component is just deleting itself on play mode for multi screen setups?​

ANSWER: For ProTV 3, that's intentional. The VRCAVProVideoScreen components should only be on the VPManager game objects. ProTV 3 uses a different rendering pattern than ProTV 2 or some other video player assets. All you need to worry about is making sure you have the materials assigned correctly to your mesh and the TVManager object in the Rendering Options.
Having multiple AVProVideoScreen components for a single AVProVideoPlayer is a performance hit, so we enforce removing extraneous copies of that component where appropriate.
Any of the ones that get removed automatically, you can just remove manually to avoid the confusion.

Some of my text in my scene is blocky or square. What's wrong?​

SOLUTION: If any of the text looks block-y or square, you will likely need to reset the z scale of the UIs.

  • Go to each affected Canvas component that has broken square text under it, right click the respective GameObject and select the ProTV -> Utility -> Reset Children Z Scale menu action.
  • This will go through each child transform and find any incorrectly scaled Z values that are set to 0, and update to an appropriate value.
  • This particular fix is mainly for TextMeshPro shader requirements.
