Failed to create RenderManager (Windows 10 x64 AU)

[demonixis]

Hi,

Since the last HDK2 firmware update, I can't use Unity apps. There are the logs I have

Crash dump can be downloader here

Hi,

Could you tell me what firmware version are you using?
Did you try to rollback to the previous firmware version?

Best,

[demonixis]

Hi,

I use a HDK 1.4 and a HDK2 The HDK 1.4 uses the firmware 1.96 and the HDK2 the 1.97. The problem occurs only with the HDK2, the HDK 1.4/3 seems to work fine.

With the stock firmware (HDK2, 1.01 if I remember well), Unity apps worked well. When I updated my HDK2 to the latest firmware, I was not able to use any Unity application. There are two problems. The first is this one reported in that issue. The second is that a compiled game can start, shows an image for 1 sec and crashes (Take a look at the link provided in my initial post, there is a crash dump generated by Unity).

[osvr-phabricator]

Hey,

Could you please also share with me:

1. OSVR-Server (version or revision).
2. Rendermanager (version or revision).
3. drivers installed (version).

Are you building and installing the latest revision of these components or using the installer?

Thanks.

[demonixis]

Hi,

I use the oneclick installer.

OSVR-Core: v0.6-1320-gc0575b0
RenderManager: ?
Drivers: NVIDIA 372.70

I don't find the RenderManager DLLs into the installation folder

[osvr-phabricator]

Thanks for all the answer, I'm trying to replicate the problem, will get back to you soon.

[osvr-phabricator]

I forgot to ask you one more thing in my previous email.

Which graphic card are you usin?
What is the driver version?

Thanks.

[demonixis]

Hi,

I'm using a GTX 970 with 372.70 drivers. My HDKs uses the direct mode. It works with the HDK1 but not the HDK2. The two HDKs have the latest firmware (1.96 for the HDK1 and 1.97 for the HDK2).

The onclick installer seems to be a 32 bit build because it's installed in c:\program files (x86)

[VRguy]

Yannick,

The HDK2 ships with version 1.01. It has several bugs which are being
addressed, but if it worked for you before the upgrade to 1.97, you can
downgrade it back. Do you need the HEX file for 1.01?

Hi @VRguy

Yes it worked before, you can send me the hex here, thank you.

[demonixis]

I have flashed the HDK with the stock firmware but it doesn't work.

I have created a blank project, downloaded the latest Unity SDK from https://osvr.github.io/build-with/

I got this error (just one)

[OSVR-Unity] Failed to create RenderManager.
UnityEngine.Debug:LogError(Object)
OSVR.Unity.DisplayController:SetupRenderManager() (at Assets/OSVRUnity/src/DisplayController.cs:143)

OSVR.Unity.DisplayController:Update() (at Assets/OSVRUnity/src/DisplayController.cs:317)

@VRguy newer firmwares are better, with the 1.01, I have a crash at start. With the 1.97, the application starts, displays for 1 sec then crashes...

[demonixis]

Hi I changed my GPU (From a GTX 970 to a RX 480) and I have the same problem. Note that since I updated all my sofware (Unity, OSVR, GPU drivers, Windows, etc...) Unity apps doesn't work with the HDK 1.x and 2.

My configuration

CPU: Intel core i5 3350p @ 3.1Ghz
GPU: RX 480 8 Gb
GPU Drivers: 16.8.3
OS: Windows 10 x64 Pro Anniversay Update (1607)
OSVR-Core: v0.6-1320-gc0575b0

I use the oneclick installer, note that it doesn't contains

• RenderManager
• EnableOSVRDirectModeAMD.exe
• DisableOSVRDirectModeAMD.exe

HDK 1.4: Firmware 1.96
HDK 2.0: Firmware 1.97 (Reverted to 1.01 with no change)

[demonixis]

Hi again,

I can conforme that the HDK2 is working fine with RenderManager samples (inclued in the SDK) and with SteamVR. I don't have tested the HDK with Unreal yet, but for now it seems to be related to Unity only.

[DuFF14]

Unity/RenderManager is working for me with HDK2 firmware 1.01, 1.96, and 1.97, and also HDK1.x with firmwares 1.92 and 1.96.

I'm currently using 1.01 and 1.92 (from the one-click installer) without issue, at least with x86_64 Unity builds. There is an issue with x86 builds (but not editor).

I did see the problem where it crashes after 1 second. This occurred on HDK2 after switching from 1.97 to 1.01 firmware and running the Palace demo. I power cycled, restarted, and updated the demo and haven't had the issue since. Not sure what causes this because it was working on 1.01, 1.97, and 1.96, then started misbehaving after switching back to 1.01, then the issue went away. I'm testing on a GTX 1080 with NVIDIA driver version 372.70.

I just updated the Palace Demo, could you see if this version works on your machine? https://github.com/OSVR/OSVR-Unity-Palace-Demo/releases/tag/v0.6.14

I'm still looking for issues with x86/x64 server and Unity build combos. The Palace Demo is a x86_64 build. If I change to x86, it fails to create rendermanager in the build, but not in the editor.

[demonixis]

Hi,

I have tried the palace demo, I was able to start it two time and it worked for the HDK2. However, it seems that there is no distortion correction and no dynamic light (or missing lightmaps?). I use my HDK2 in direct mode on a RX 480 (latest driver).

Then I tried to copy the dll from the palace demo plugin folder, to the plugin folder of one of my projects. It's not working, and I've this message:

[OSVR-Unity] GL.IssuePluginEvent failed. This version of Unity cannot support RenderManager.
UnityEngine.Debug:LogError(Object)
OSVR.Unity.VRViewer:UpdateEyes() (at Assets/Vendors/OSVRUnity/src/VRViewer.cs:193)
OSVR.Unity.VRViewer:DoRendering() (at Assets/Vendors/OSVRUnity/src/VRViewer.cs:264)
OSVR.Unity.VRViewer:OnPreCull() (at Assets/Vendors/OSVRUnity/src/VRViewer.cs:240)

This is a message from Unity 5.5, I'll try with Unity 5.4 (at work), but Unity 5.5 has some improvements and is pretty stable for a beta so I develop my games with it.

In any cases

• RenderManager samples => Works all the time
• Unity Apps => Work one or two time, doesn't work anymore on Linux (see that post on reddit as an OSVR Game Developer for Linux too, it's hard for me to give answers to players of my games...)
• SteamVR works well

[DuFF14]

Can you clarify what you mean by "works one or two times"? What happens the third time? If it drops USB connection, that may be a firmware issue. Are you using 1.01?

It shouldn't work on Unity 5.5 because that hasn't been added to the code, but it's an easy fix I can make today: https://github.com/OSVR/OSVR-Unity/search?utf8=%E2%9C%93&q=UNITY_5_4&type=Code
