OpenVR-InputEmulator Latest steam update broke Input Emulator

It just crashes SteamVR on start and then SteamVR blocks it. Don't know how to fix it.

Same issue. Hopefully it’s just a simple bug in the new update. But I think that input emulator is failing to pick up devices and is crashing. But that’s just my theory.

Same issue here, it started happening sometime in beta and had to opt out of beta to get it working again, but now it affects the new released version.

Issue is most likely caused by IVRServerDriverHost_005 needs updating to IVRServerDriverHost_006 which was introduced in beta.

Noticed this yesterday, I saw another solution implemented successfully for for Natural Locomotion, described fix here

"Seems like IVRServerDriverHost got updated to version 006 in the driver DLLs, so if you're lucky changing the hook to look for the new version string might be enough."

A new hotfix has been released for SteamVR which may fix the issue.

Hmm, just tried updating steam and steam beta, still not working. is there something I need to do to pick up this hotfix, or is it just "wait a bit" and it will become available?

would be great if someone with some knowledge could release a fixed version. this is completely broken as of last update. :c

The project is abandoned sadly it may never be fixed

Yeah, I even tried to grab the source code, searched and found the "IVRServerDriverHost_005 ", added a IVRServerDriverHost_006, saved it and now wtf do I do lol! Downloaded Microsoft Visual Studio, but that can't compile to an exe unless it's the commercial version, so I tried the free approach with minGNW, but holy cow that is not point and click it seems, so I wasted some serious time on what would seem to be a cakewalk for someone, anyone, in the know.... which is not me :)

I can't complain though, without the effort already donated by those before, we wouldn't have anything at all, so when they get to it, cool with me. And Thank You to matzman666 and those that contributed this, and all the other cool stuff!

Sep 19 '20 02:09 thoskee

im not sure what it takes to compile this, but please dont give up! i believe in you :p

Try this dll please, it should work. https://drive.google.com/file/d/1gXVxXRuNq0yIJpClagKKyWHBCcG0zfPy/view?usp=sharing dll to be put in "SteamVR\drivers\00vrinputemulator\bin\win64" let me know if it works...

Sep 19 '20 14:09 p1mp184

To p1mp184.

From what I've tested, what you've created is a complete repair of the OpenVR-InputEmulator that was broken in the SteamVR update. All those people who were having trouble with this issue will thank you.

Sep 19 '20 14:09 RuneOcean

this works for me. thank you so much.

Sep 19 '20 15:09 fwenny

question for people using vive, does it feel jittery and laggy for you when you move your head with input emulator running?

Sep 19 '20 16:09 fwenny

Awesome, now I don't have to think! Works great, I thank you p1mp184, my wrists also thank you.

Sep 19 '20 17:09 thoskee

I had thought so on occasion, wasn't sure if it was this, or OPenVR advancedsettings, decided it may be both add a tiny bit?

Sep 19 '20 17:09 thoskee

So is this something we need to do each time steam client updates, or only when the client occasionally changes the dll in question?

Sep 19 '20 17:09 thoskee

This time we have been lucky, but who knows what the next steamvr update would break. I suggest to create a copy of the current complete steamvr folder, which works. In the future in case of issues it should be possible to replace the new steamvr folder with the old one and it should work again... Until the next update again... Glad it worked this time though

Sep 19 '20 17:09 p1mp184

i have a friend who gets really bad jitters when input emulator is running, and none while it is off. only started after latest steamvr update. wondering if someone else has that issue.

Sep 19 '20 17:09 fwenny

Weird interaction with playspace mover. Only my hands move and they move in strange directions. Not sure if you even have any control over this but I'd be grateful if you knew anything about it. Thanks!

Additional question unrelated to this particular fix, as it existed before, and I was just reminded by the previous poster, so when I switched to the HTC Vive and Index controllers, from Rift S, the X Y Z offsets were drastically different in there effective axis between left and right controllers, as well as vastly different from Rift S, which the Rift S was exactly as you would have visualized. I understand the axis between controllers are going to behave different, however the index controllers would be different by a seemingly random shift of degrees for X Y and Z, and all different (the axis and the degrees)

Sep 23 '20 04:09 thoskee

I assume it's related to the particular Base Station being referenced, and the two are positioned slightly different, opposite corners, but is there a better way to help me picture the shift in position needed?

Sep 23 '20 04:09 thoskee

Uhm...I do not know "playspace mover". The only thing I did was to re-trace the hook previously defined as "IVRServerDriverHost_005" to "IVRServerDriverHost_006" and then re-compile. Maybe some other applications still need the "IVRServerDriverHost_005" hook. I should try to keep also the old hook and re-compile. Big problem is that my PC is without a GPU now and therefore cannot be switched on at all.

Sep 23 '20 06:09 p1mp184

Can someone say the full directory. I can't seem to find the folder.

Sep 27 '20 20:09 CAYOK

should be in your SteamVR folder (Steam\SteamApps\Common\SteamVR)

Sep 27 '20 20:09 fwenny

Still crashes for me, only when I try to connect my Quest. Tried uninstalling and reinstalling, verifying the .dll file. Any ideas? driver_vrinputemulator.log Edit: I think I've narrowed it down to me using ReLive to wirelessly connect to my (AMD) computer. Does anyone else have this issue and what can be done to solve it? Thanks!

Hey, is there any chance you can also do this for the Space Calibrator driver? My system is broke as the Calibrator driver will not load with the latest SteamVR. :-/

Perfect! I am building a motion rig and without this, I could not play in VR. Thanks so much

Oct 04 '20 15:10 RISCy79

You are a life safer! Like so many I'm using InputEmulator for a motion sim rig, thank you so much for your work. Is there any way I can buy you a coffee or a beer for your efforts?

Oct 12 '20 01:10 phutflesz

hi.

I corrected some things in the dll. Maybe now it works better. Here's the link. https://drive.google.com/file/d/1kBEdyLRKxEtB5nLOKDfs_JpmkMj4fwHY/view?usp=sharing

Oct 25 '20 02:10 p1mp184

Hey man, could you commit the amazing changes you made in a new branch on the repo? It would be awesome
