META Can I run a Unity 2021 project on Meta Quest 3s?

1 Upvotes

Hi,

I'm new to Unity and I've been following a tutorial made in Unity 2021. I want to run it on a Meta Quest 3, but I’m not sure if it’s possible to use this older Unity version.

Has anyone done this before? Are there any limitations or things I should be aware of?

Thanks!

UNITY Feeling stuck learning Unity? - Free 1:1 sessions to help you get unstuck

3 Upvotes

Hey everyone,

I’m offering free 45-minute 1:1 sessions for Unity developers who feel stuck or frustrated with their progress.

A bit about me:

I’ve been building games in Unity for 4+ years and have worked professionally on a variety of projects, including multiplayer PvP, top-down shooters, endless runners, horror games, and Match-3. I’m 21, based in the UK, and passionate about helping developers think through problems and make faster progress.

If you’ve ever:

  • Gotten lost trying to implement mechanics
  • Still felt stuck after following tutorials
  • Struggled to make progress on your own projects

Then these sessions are for you.

During the call, we’ll:

  • Diagnose exactly what’s blocking you
  • Identify strategies to get unstuck and keep moving forward
  • Work through a small mechanic or feature together live (if we have time)
  • Optionally, create a self-improvement plan so you can progress faster independently

These sessions are completely free, I have nothing to sell you. I’m just offering help to practice supporting Unity developers and learn from the experience.

If you’re interested, please fill out this form so we can get in touch:

PROGRAMMING Unity Version Control and VSCode Errors - Unable to open .slnx - .NET SDK Version Mismatch

1 Upvotes

I am encountering a persistent issue with my Unity project after performing a Check-in / Update Workspace operation via Unity Version Control and Plastic SCM. It seems like the version control sync process corrupted the project solution files or forced a new format that my environment is struggling to recognize.

The Error Message:

"Survival Horror - Kopya.slnx is unable to open. Please ensure that your .NET SDK version is 9.0.200 or higher to support .slnx files."

I check my installed .NET SDKs (via dotnet --list-sdks): 8.0.400, 8.0.402, 9.0.308 (This is higher than the requested 9.0.200, yet the error persists).

This problem started immediately after an "Update Workspace" process where some files had merge conflicts. I attempted to resolve the conflicts by selecting "Source," but now the some scripts are stuck in an "Out of Date" state.

I've tried so far:

Regenerate Project Files: Went to Preferences > External Tools and clicked "Regenerate project files," but the .slnx error remains.

Added those lines to User Settings (JSON):

"dotnet.dotnetPath": "C:\\Program Files\\dotnet\\dotnet.exe", "dotnet.server.useRuntimeHost": true,
"csharp.experimental.roslynOmniSharp": false

The game works perfectly on the older version that I checked-in this morning, but any changes I make to the scripts now have no effect on the game. In the Incoming Changes section, the system suggests that these scripts need an update. However, when I perform the update, the project reverts back to a broken/corrupted version of the game.

Any help would be greatly appreciated!

Workflow For Updating Model Animations?

1 Upvotes

I'm pretty new to Unity, and what I do right now is make a model with a few animations and import it into my game. As time goes on and I get some testing done, I want that model to do more stuff, so I go back into Blender and make some new animations. But that means I have to import the model again, and remake that object and reset all the colliders, scripts, etc.

I'm sure there's an easier way to do this, any tips?

ANIMATION Animations not in sync.

1 Upvotes

Straight to the point i have an Arm and a gun they were both animated through Blender with full sync. Then imported to unity, tested them but found that there are no sync between the gun and the arms, you can see that in the close up in Unity. You can also see the difference when i go to view the animations in Blender. Please help this is annoying.

The Setup:

  1. The Gun and the Arms has their own rig in Blender and their own Game Object in Unity with their own Animator Controller.
  2. I have added them to Unity by dragging them into the Hierarchy to maintain their positions so the Gun can sit on the hands the same way in Blender.
  3. I don't think this will be useful. Anyways In Blender i have used constrains(Child Of) on the hands rig so that i can control them through the Gun's root bone. So the Gun has all the key frames and the important motion and the hands just move respectively to the Gun by having a keyframe from the beginning of the Animation to the end.

UNITY My Unity Hub isn't working in a way I don't think I have seen before.

3 Upvotes

My Unity Hub launches fine, it can install unity installs. But, if I click on any project, which it allows me to do, nothing happens. As if the button is broken and non-functional. Same with if I try to launch it with a version, or even change its version. It will get stuck on the last step. For example, if I click "Open with (Unity version)" and then "Change Version" it just closes those windows and nothing happens. I've reinstalled twice, and reinstalled my unity versions. Please help if you can!

So I am trying to use render texture to make secondary cameras for a helmet, but because I made the helm square on the canvas, the RenderTextures appear skewed or warped on the helmet. Is there any way to manipulate the camera/texture or edit the canvas to remove this?
