Eh? What same error? I don’t have a previous post from you in here and that hasn’t been reported here before.

Do you have a full log file for it? Also are you on windows? Because any other platform you’ll have to manually compile due to me not having the required hardware to compile for it.

Usually errors like that are caused from stale Intermediate folders in the project files, which you generally just delete to fix (they re-create then), however if you are using the pre-built on a new project then that shouldn’t be the case and it shouldn’t be trying to re-create it anyway.

1702

I think he means the same error as I am getting

1703

Mmmm, no I don’t. WheeledVehicle.h didn’t change locations in 4.18 and that is the same include line as before. I built and packaged entirely on 4.18 without issues even in a non unity build.

There actually isn’t an alternative path to that file available and its module is included.

You don’t have the plugin module PhysXVehicles disabled do you?

1704

its not the same error though, he isn’t generating an OpenVR pdb file, while you can’t find a header file so the main VR Module is having issues.

guess just a misunderstanding, i’m adding the pre-built to a clean project to see if packaging messed up somehow last night.

1705

Hmm, nope PhysXVehicles is enabled. The plugin has been working fine in 4.17.2, but I can’t seem to update to 4.18 because Visual Studio doesn’t compile. I’m gonna do a bit more research.

I’m not sure whether it’s because of 4.18 or plugin, I thought it was a 4.18 issue so I already filed a bug report:

https://answers.unrealengine.com/que…ual-studi.html

(its a different error, but they might be related)

1706

Oh, that is definitely a UBT error, its in your projects intermediate files, not the plugins.

Are you still on visual studio 2015 or did you update to 2017? They added visual studio code support for 4.18 and it broke things a few times during previews, but so far I have been fine on release.

1707

Ah, I am using 2017 now. I’ll try going back to 2015, see if that works.
( I already tried deleting the Intermediate, Saved and DerivedDataCache folders)

1708

Think 2017 is more stable now, was making sure you hadn’t recently upgraded or were still on 2015.

Delete ALL intermediate files (including in plugin folder) and then “switch” engine version back to 4.18 (even if still on it).

1709

I thought the UBT errors were the same, my mistake, sorry if I caused confusion :slight_smile: I’ve no idea about Visual Studio or coding.

I’ll get the log when I’m back on the PC (Windows). It’s an existing project brought forward from 4.17. I installed 4.18, updated the plugin using the prebuilt download. I deleted saved and intermediate from the project folder, generated the visual studio files and then tried to compile.

1710

Can you post the rest of the log in CODE tags or pm it to me?

I don’t know if you are also having UBT issues but that last line doesn’t say anything specific.

1711

Will do. Be a few hours time before I get back.

I cleared the intermediate folders in the two plugin directories as well, and it seemed to be working OK at first, then it failed again.

I am currently testing out the content example and every time I start previewing in steam VR, the play area rotates randomly and is never in a fixed position, how can I disabled it?
Its like your using “Reset Orientation and Position” and executing it again does not work

1713

I think our problem is fixed, there was old C++ code that didn’t work anymore (SetupBinaries())

Thanks for the help, I supported you on Patreon today for all the good work!

1714

You are welcome and thank you.

I’ll note that you have access to the discord now, you should totally make use of that. I idle in it at work and when coding at home and answer questions all day. Users in there also throw ideas back and forth.

1715

Ah there we go, thanks for the log it gives me what I needed.

When you updated to the 4.18 version of the plugin you must have just dragged the files in to the folder, you should have deleted the current contents first. GripSteamVRTrackedDevice was not overwritten with a new version for 4.18 because it has been removed entirely from the plugin (is no longer required).

You can feel free to just delete the GripSteamVRTrackedDevice.cpp and GripSteamVRTrackedDevice.h files, but I would suggest that you delete everything and re-copy the files in to make sure nothing else is left as its legacy version.

1716

Yes, I dragged it in and overwrote the files that were there. I now know for next time now, thanks for the help.

The plugin is excellent, I tried to do a lot of the setup myself but when I saw did a much better job I started porting things over. I’ve used your template as a guide and built it all up modifying your work where needed. Its been a massive, massive help so thanks. I’ll pledge on your patreon for the help here and for the work for the plugin :slight_smile:

EDIT: Its all worked fine time!

1717

Does VR template support gravity? If I was to walk off the edge of the nav mesh/ground would my character fall like gravity? Thank you

1718

Yes…Its the full normal character but for VR. It supports all of the movement modes and capabilities of a standard character (plus some).

1719

I am sorry, but another basic question. I have been watching a lot of your videos/demos and I am curious if template supports teleporting? I prefer the teleport method for movement and not hoover/sliding along the ground. I like the Unreal VR Template teleporter or similar. Would it be hard to set that up for template? Thank you

1720

The template includes a great number of movement options, including standard teleport
