If the FAQ does not cover your issue try the Discord link on the bar in the right. Someone there can likely help you. You can also try the forum.
Can I play with friends?
Yes! Vivecraft can be used to play on any normal Minecraft server running the same base Minecraft version. You can play with anyone, VR or not.
The VR features you can use in multiplayer depend on the server configuration. See the Multiplayer page for more info!
Can other people see me move in VR?
Yes! With a little work. You will need to be on a server with one of our server plugins, and you, and all your friends will need either Vivecraft or the Vivecraft Non-VR companion mod.
How do I play Minecraft?
Check google or youtube for tutorials
Why can’t I jump?
Vivecraft disables jumping and falling in teleport mode for those prone to motion sickness. Enable them in the VR Settings > Locomotion Options menu by turning ‘Simulate Falling’ on.
Why can’t I teleport?
When you connect to a multiplayer server that does not report running a Vivecraft Server Plugin the movement mode will default to free-move so you do not get kicked for cheating. If you know the server allows teleporting you can switch back to it by holding the ‘Pick Block’ button for 4 seconds or from the VR Settings > Locomotion menu.
Why can’t I type in game?
Using the in-game keyboard (and several other mouse-related things) requires that the game window is in focus on your PC. If you alt-tab or click off it in Desktop mode be sure you switch back to it.
Can I play with mouse/keyboard?
Yes you can. Change ‘Play Mode’ to ‘SEATED’ in the VR Settings menu.
Can I play with a gamepad?
Does Vivecraft work with Forge?
Yes! See the Downloads page for installation instructions, and this page for individual mod compatibility info.
Does Vivecraft work with LiteLoader?
Yes, but only on 1.7.10. Install Vivecraft with Forge then extract the LiteLoader .jar and put it in your /mods folder.
Can I use Vivecraft with mod packs?
Yes!. See installation instructions below. Check the mod compatibility chart if you encounter any issues, individual mods in the pack may not work.
Using the FTB / Curse / Twitch / Technic Launcher
- Use the mod launcher to download your desired pack. Note the directory where it installs.
- Run the Vivecraft installer.
- Check ‘Install Vivecraft with Forge’
- Check ‘Custom Profile Name’ and enter in a custom name, if desired.
- Check ‘Modpack Directory’ and click the … button to browse to the modpack directory. This is the directory containing the /mods folder for the desired pack.
- Install Vivecraft and use the official Minecraft launcher to play your custom profile.
Below is an example for launching the DW20 pack for 1.10.2 installed via the Twitch App.
The game runs poorly, what can I do?
Minecraft was not written for VR and is not a very well optimized game. Here are some steps you can take to improve performance
- Make sure you are allocating enough RAM for your installation type. Additionally be aware it’s possible to have your Java heap space overridden by Windows environment variables. If the game run incredibly bad check for a unwanted -Xmx256M argument there.
- Reduce your draw distance in the Video Settings menu. Below 10 is best, even for high-end systems.
- Turn down the ‘Render Scale’ in the VR Settings > Stereo Rendering menu. Also make sure your SteamVR supersampling is at 1.0, Vivecraft has its own setting and will stack with SteamVR’s.
- Make sure you are not using any custom shaders or texture packs (in Video Settings).
The motion controllers don’t respond at all
Make sure the game is set to STANDING play mode. Use the mouse to navigate the menu to the VR Settings screen and change it there.
The game shows up on my desktop, but not in the headset!
This occurs frequently on systems with dual GPUs like Alienware laptops. The solution is to force your PC to always use the gaming processor. For NVIDIA systems in the NVIDIA control panel set the Graphics Processor option to ‘High Performance’.
The game crashes on startup, what should I do?
You will need more information about the crash.
Go to your .minecraft/crash-reports directory and look for the latest file. Additionally you can try the .minecraft/logs directory and look for ‘latest.log’. (If you are using Forge on 1.10+ look for ‘fml-client-latest.log’ instead). The last entry in this file should be the crash stacktrace.
Once you have located the error, check the common ones below. If your crash is not listed, come to the Discord or Forum and bring your log.
The game crashes and the error says “MalformedClassName”
Go to your .minecraft directory and delete usercache.json. That should sort it.
The game crashes and the error says “java.lang.OutOfMemoryError: Java heap space”
Check your Windows environment variables for something that is adding a Xmx256M or similar argument to your java commands. Remove it.
The game crashes and the error says “Could not reserve enough space for 2097152KB object heap”
You do not have 64 bit java installed. install it or remove the -Xmx2G argument from the Vivecraft profile.
The game crashes and the popup window says ‘Java Binary SE has stopped working’
This is caused by a buggy nvidia driver released in January 2017 (v378.49). Try updating your drivers.
The game (or the installer) crashes and says ‘EXCEPTION_ACCESS_VIOLATION’ in ‘d3d9.dll’
This is caused by an incompatibility between Windows 10 creators update, 64-bit java, and Rivatuner. You will need to either uninstall or update Rivatuner.
