Vive Sculpting Tool Crash

[CScornwell]

On Windows 10 pro-64-bit, with HTC Vive: I followed the steps provided https://www.marui-plugin.com/blender-xr/#download and downloaded from those links. The plugin works fine before opening a VR window and using the sculpt tool. It instantly crashes to the desktop upon using the sculpt tool in the VR window on anything more complex than a cube (default primitive). The issue appears much like the previously reported bug with the Oculus Rift, I'll link the Rift users' video for reference: https://youtu.be/xoHUA8AUn5Q

I am currently running Blender 2.8.1. The patch does not appear to have corrected this error.

Sorry, I can't reproduce this.
Is it possible that it's related to your graphics card / driver?
Is the sculpt tool really the only tool that crashes? Other tools are working fine?

Hey Guys
Same issue here as soon as I use a sculpting tool everything crashes. Do you have log files, Or a should i try and run this in shell and watch the output?

My Current Specs:

• Graphics Card: RX 5700
• CPU: ryzen CPU 3500
• VR HMD: WMR lenovo

Software

• Windows 10
• Installed before BlenderXR: Blender 2.82
• BlenderXR Version: 20200102
• additional files: blenderXR_steam.dll, openvr_api.dll for WMR

Update I got this error Running in Power-shell :

Error: EXCERTION_ACCESS_VIOLATION
Address: 0x00007ff6B729095E
Module: C:\User******\Desktop\BlenderXR_Windows_numbers\BlenderXR_Windows_numbers\blender.exe

I moved the files to Downloads and still it wont work

finally got something to work however as soon as I get it in dynamic topology and try to sculpt it crashes right away.

The controls are nice but on bigger files with my beefy hardware it just studders toooo much
only sometimes dose it allow me to sculpt but most of the time it as if nothing happened

Going to try some more testing Ill let you know how it goes;
Ive been mostly programming on mac since 2013 and really having issues getting used to Windows again

Latest Update
Supper glitchy crashes all the time

I put the program in Program files with correct files and i still get crashes
I ran power shell as admin again in program files .blender.exe

Here is what was returned upon crash

Error : EXCEPTION_ACCESS_VIOLATION Address : 0x00007FF678D93405 Module : C:\Program Files\BlenderXR\BlenderXR\blender.exe

Same issues here.

Software:
Windows 10
Blender 2.82a - installed prior to:
BlenderXR 2.81 (20200102).
BlenderXR_SteamVR.dll & openvr_api.dll for WindowsMR

Hardware:
CPU: i7 5820k
GPU: GTX 980ti
HMD: Valve Index

• The toggle for dyntopo does not work correctly nor does dyntopo itself. Attempting to turn dyntopo on usually causes a CTD.

• Changing sculpting tools with too many polygons loaded (i.e. the default sphere in the default sculpting file) always causes a CTD

• Attempting to use the default sculpting tool on the default sphere in the default sculpting file always causes a CTD.

• In addition, BlenderXR 2.81 (20200102) does not recognize my graphics card for CUDA rendering.

Everything else seems to be okay - mind you I've only been able to play with it for an hour or two so far since sculpting and visualization are my main scopes of use.

(I'll mention that it would be real handy to have orientation locks that can be toggled on and off while manipulating the view by squeezing the grip sensors. I.E. disable pitching, rolling or yawing & reset pitch/roll/yaw to zero when it is desirable to keep the scene coplanar with the real-world floor. It would help prevent sinking into/rising above floors when navigating the 3D scene.)

Running into same issues here, can't even try it out.

Software:
OS: Windows 10 1809
Blender: BlenderXR 20200506

Hardware:
CPU: i9 9900k @ 3.6 GHz
RAM: 32GB DDR4
GPU: GeForce RTX 2080 Super (Driver: 451.67)
HMD: Valve Index
Controllers: Valve Knuckles

Steps:

1. Launch BlenderXR
2. Select sculpting start file
3. Changed MatCap to clay (probably doesn't matter)
4. Start VR Window
5. Set left hand radial to sculpt strength menu
6. Set right hand to sculpt grab tool instant crash

Terminal Output:

Error   : EXCEPTION_ACCESS_VIOLATION
Address : 0x00007FF6E089A365
Module  : C:\Users\Andrew\Downloads\BlenderXR_Windows_20200506\blender.exe

Note: Blender is not generating crash logs for this.

Edit: Decided to build the project and do some debugging since I really love the idea of this plugin. If I happen to find anything more I'll add it on here.

I have the same issue.

Win10 1909
Ryzen 3700x
32GB RAM
RTX 2060 Super -latest drivers
HMD: Valve index - complete kit bought week ago, latest firmware and latest regular release steamVR.

Downloaded BlenderXR_Windows_20200506 and the two DLLs for vive. It works fine till I start sculpting. I started with cube and it let me with dynamic topology sculpt it to sort of elongated sphere, then it crashed. When I started with sphere it just crashed when I touched it with sculpt tool. It generates folder but no log, it just instantly crashes.

EDIT:
I tried it again starting with the cube and it actually let me sculpt for a long time. 15-30mins max. Then it crashed again without any logfile. However it was long enough for it to create autosave file! Which when I try to open again just opens blender and instantly crashes. I attached the autosave file, it might be useful?
