VR Expansion Plugin

You likely have fracture on impact turned on and it is colliding with it.

ryan326 · March 13, 2017, 11:48pm

Hi Everyone,

I tried getting project to work in 4.13 and 4.14. Each time with different issues. In 4.14 it’s saying VRExpPluginExample could not be complied. Try rebuilding from source manually. When I try to build in Visual Studio it says SteamVRPrivate.h No such file or directory.

In 4.13 I got the project to open in unreal but when I tried to load the SteamVR Game Override it would do nothing a say the package failed to load.

Is anyone interested in getting paid to help me set project up and get it working… Please help.

mordentral · March 14, 2017, 12:45am

You need to use the 4.14 locked branch, you downloaded the 4.15 version.

Sleeper_1 · March 14, 2017, 9:14am

I’d like to note that in one of the instructions you still say it’s only compatible with 4.13 and 4.14, which also got me confused

anonymous_user_3b4c8d46 · March 14, 2017, 9:16am

It is compatible with multiple versions although, there are releases of the plugin corresponding to each UE version. In other words, there is no universal plugin release which works on all the UE versions.
I hope that explains things to you guys (=

You mentioned increasing the client bandwidth limit for Steam Voice. Is that accomplished by increasing the following in DefaultEngine.ini do you know?

[/Script/Engine.Player] ConfiguredInternetSpeed=10000 ConfiguredLanSpeed=15000

I’m thinking these values are really low as they stand. Are there any other net settings to change as well as these?

Thanks.

mordentral · March 14, 2017, 12:51pm

mmm, i’ll update that, probably shouldn’t list specific engine versions

Not to each, to each with a major code path change that made it difficult to continue forward as a unified branch.

4.13 introduced a ton of navigation changes that would have required me to double the code in the path following component to support the old version as well (with compilation defines) so I broke it out separately.

Then 4.15 changed how module headers work engine wide, and while I could have kept that one cross compatible it also made the old style enums deprecated, which is a larger problem. I couldn’t change over to the new enum style for 4.14 and 4.13 because they didn’t support replication of them yet and I didn’t want to manually replicate bytes and convert back and forth just to support older engine versions.

I don’t have that much of a problem in my mind locking out branches currently, 4.15 is the first mostly stable VR branch as far as I am concerned (with 4.14 being the first real VR release). Specific features missing from locked branches could be pulled in from the later branches if needed by someone.

From what I have seen new the Unreal Tournament is using 15000 bps for clients in internet servers, which is the engine LAN default.


 [/Script/OnlineSubsystemUtils.IpNetDriver]
 MaxClientRate=15000
 MaxInternetClientRate=10000

 [/Script/Engine.Player]
 ConfiguredInternetSpeed=10000
 ConfiguredLanSpeed=20000

Would be


 [/Script/OnlineSubsystemUtils.IpNetDriver]
 MaxClientRate=15000
 MaxInternetClientRate=15000

 [/Script/Engine.Player]
 ConfiguredInternetSpeed=15000
 ConfiguredLanSpeed=20000

Configured speeds are that the server allows the clients to set I believe.

UT also uses a lower tick rate than default I think though, but they might just be using their Opus integration, I think that steam VOIP has higher bandwidth requirements.

mordentral · March 14, 2017, 12:59pm

Oh, that was the template saying that, not the plugin itself. I changed it to say latest version for the template, its not going to load on previous versions anyway due to the map file.

Hey, I’m pretty new to UE4 in general and wanted to check out the template. When I try to build the solution, I always get the following error:

Edit. Using 4.15

Edit2: Solution was to change back from Visual Studio 2017 to 2015

mordentral · March 14, 2017, 3:24pm

The illegal qualified name was a legit issue, generally VS compiles through that anyway but it shouldn’t be left in, I just fixed that (from time to time it sneaks in).

The enum names being generated incorrectly by the UBT isn’t a plugin problem though, someone had the same issue upgrading to 4.15 with their project and they had to delete intermediate files and recompile. If you are just doing your initial compile though it shouldn’t have that problem.

What version of Visual Studio are you running on?

a2uinteractive · March 14, 2017, 3:53pm

I’m using Visual Studio 2017, maybe that’s the real issue here and I should rather go back to Visual Studio 2015.

mordentral · March 14, 2017, 3:59pm

Yeah I would try 2015, 2017 support just came out for the engine and I doubt it is perfectly ready yet. Throwing build errors on auto generated content from ue4 throws red flags to me about its readyness.

Edit
People seem to be saying that the 2015 build toolchain still needs to be used with 2017 when compiling, but that they are using 2017 for the text editing and intellisense. So basically keep 2015 installed and edit with 2017 if you wish.

IslandPlaya · March 14, 2017, 4:08pm

VS2017 caused me no end of problems… Reverting back to VS2015 Community fixed it. Recommend using 2015 for the time-being. I think 4.15.1 will have some VS2017 fixes…

a2uinteractive · March 14, 2017, 4:35pm

Thanks guys, will do so and report back.

Edit: seems to be building fine now! Thank you again for the quick help

Magneto · March 14, 2017, 5:11pm

If it works like a typical widget then yes, you just use Epics widget interaction components, the template has an example for base functionality with them.

mordentral · March 14, 2017, 5:44pm

Edit Never mind I see you are trying to use the example project. That only loads on 4.15 due to the map files and content being on 4.15, its harder to keep working across versions.

The template is also using the 4.15 version of the plugin since it has to be on 4.15 itself.

The plugin itself has multiple versioned branches, its just the template project that doesn’t. I updated some of the readme’s on the repositories to make more clear today.

ryan326 · March 14, 2017, 5:53pm

I have tried multiple files, the above steps were from file, https://bitbucket.org//vrexppluginexample

The c++ component should be installed I have it working for other games. Is there a way for me to check?

I also did the locked 4.14 files and got the different errors below:

Read the post above it, you are using the Template project which is 4.15 only, it wouldn’t load regardless.

Also if you change the plugin in the template to an older version than you will need to delete the intermediate and binary folders for the plugins probably, and the template map will still not load and you will get blueprint errors (could probably still be used for reference).

Also please please use code tags for long text.
