I have an issue with 1 experience potion ( should contain 5 exp points I guess) in the nightmare academy checkpoint 13

---------------------------
Fatal error - Data is corrupted.
---------------------------
ERROR: Data in texture5.fbq is corrupted. Checksum failed for file: data/root/instance_base/entity/object/levels/venetian_canals/venetian_tile_roof_alt_0_roughmetallic.fbmattex

Reinstall the game.
---------------------------
OK

Im about 3 hours in. up to act 4 i think now when i try to load i just get this message.

It means that the game file texture5.fbq is corrupted. This is often caused by antivirus program falsely identifying part of the file as a virus, but could be hardware issue too (e.g. hard drive or memory being broken). You should use "Verify Integrity of Game Files" in Steam to redownload corrupted texture5.fbq, and if that doesn't help, make sure there aren't any antivirus programs messing the file.

Crackling Mire checkpoint 7 is reading 5/10 experience potions despite all 10 in that area being blue and already picked up.

[Drummar]

Turns out they were in the following area, despite seeming to count all the experience potions it's like they're all kinda shifted forward too much. Some of the experience potions in part 7 are actually in part 8, part 8 in part 9, etc. Kinda confusing to keep track of but oh well.

I try connect my controller and my left/right stick doesn't work.
All the buttons work fine include pressing the left/right stick but moving sticks doesn't work, like the game not recognize.

I try open with the STEAM big picture mode. And all the controller functions still work fine, and it recognize my controller as XBOX360 controller (I use my ps4 controller to connect with 8bitdo usb wireless.)

Is there anyway to fix this? please help.

Unfortunately Trine 4 only has native support for X-input controllers, that is Xbox 360, Xbox One and similar controllers. PS4 controllers don't generally work with the game, so if Steam's Big Picture Mode didn't help I can only recommend you to play with a keyboard and mouse instead. :( Sorry for the inconvenience!

There is a known bug with the EXP locations being counted wrong, because the game calculates the locations based on horizontal coordinates. The dev team is aware of the problem and is looking into it. The missing EXP is very likely in the previous or the next checkpoint instead, so please check both carefully and you should be able to find them.

Multiplayer is very laggy.

My friends and I tried to play multiplayer but there was a lot of rubberbanding and lag. The three of us each tried hosting but the issue still persisted. Please help.

[mjwilkins17]

The game freezes on the loading screen every time I try starting it up. Usually it'll get to the point that it says "click here to start" and then it'll freeze up. The mouse will still move around and it sometimes shows the in-game cursor, and the music will still play, but the screen is all black except for the wizard in the bottom right corner.

OS: Windows 10 64-bit
Processor: Intel Core i7-3520M
RAM - 8 GB
GPU - Intel HD Graphics 4000

I installed the most recent GPU driver version. I've also tried uninstalling and reinstalling the game. I've tried switching the GPU settings for the game to high performance, and running the game as an admin. I'm out of ideas.

Sorry to hear that! Does this only happen in online multiplayer? Also have you tried joining any random games to see if the same thing happens there too?

First, check that you and your friends have all updates installed. We released a patch earlier this year that fixed some netsync problems, so if there are any updates pending, install them first.

You can also test changing the game's settings from the Options menu, for example lower the graphics settings and resolution, or run the game in Windowed mode to check if that improves performance at all. It's a long shot, but worth testing. If it doesn't help at all then the issue is very likely with the online connection.

We've received some reports about rubberbanding/lag happening in multiplayer but unfortunately haven't been able to reliably reproduce it at our end, despite extensive testing. In Trine 4, the main online gameplay happens with a direct connection between players, using peer-to-peer connections, so laggy behaviour is usually caused by network issues at the player's end (especially the host's). There are a couple of things you can try to improve this.

Add to exceptions
Add Trine 4 and Steam to your security program's exceptions (antivirus, firewall, etc.) to make sure it's not interfering with the game's online access.

Open correct ports
This refers to the UDP ports in your router. Trine 4 uses ports from 27300 to 27315. By default they should be open in most routers, but this varies a lot between Internet service providers and countries. Check also your other router settings. Some routers have their own built-in firewall, so check that the settings aren't too strict.

Try a wired connection
If you're using a wireless connection, test the game with a wired connection instead if possible.

I recommend you and your friends all do these, since the problem can be at your end or it can be at your friends' end. Sorry for the inconvenience, let me know how it goes!

Unfortunately it looks like your GPU is below the game's minimum requirements, so the freezing is very likely caused by that. Because of this we can't promise the game will actually run on your PC at all.

If you still want to try something, you can edit the game's visual settings manually and set them on low settings to see if the game can run then. To do this, go to %appdata%/Trine4 and open options.txt in a text editor. Make sure the game is not running when you do this. Options.txt contains the game's settings, same as the Options menu. For example, set the resolution lower by editing these lines (just match the width and height with your desired resolution):

setOption(rendererModule, "ScreenWidth", 1600)
setOption(rendererModule, "ScreenHeight", 900)

Running the game in Windowed mode instead of fullscreen can also help. You can do this by editing these lines and setting them to 'true':

setOption(rendererModule, "WindowedMode", true)
setOption(rendererModule, "WindowTitleBar", true)

I also recommend turning off Vsync and setting a FPS cap to see if that helps:

setOption(rendererModule, "VSyncEnabled", false)
setOption(rendererModule, "FpsCap", 0)

Remember to save after doing any changes. If changing these settings doesn't help either, I can unfortunately only recommend you to check if you're still eligible for a refund via Steam. Sorry for the inconvenience!

The last witch puzzle is broken in online multiplayer. It's the correct solution but the beam gets blocked by the metal bars holding the mirrors.

That puzzle still bugs, apparently. Not quite the same way as this, but the result is the same: the top right stone can't be lit using the fused light beam.
We did find a wonky alternative solution using diagonal beams, though. Will post screenshot if we do it again. Only works in multiplayer.

Edit: here's the screenshot.

2nd edit: the “official” solution ended up working in multiplayer.

Sorry to hear that, but I'm glad to hear you managed to find an alternative way to progress. I've forwarded the bug report.
