I dont’ quite understand why Ralf wont add vr x,y,z position translating script himself.

Its some quite easy to do. Chatgpt created such script for me and it work fine, its not game changers but works , tested it in gta 5.
It could be tuned for steps length.

The script

import openvr
import time
import math
import keyboard  # Requires: pip install keyboard

# Sensitivity threshold (in meters)
move_threshold = 0.02  # 2 cm to detect movement
short_walk_time = 0.5  # 0.5 sec press for ~20 cm movement
long_walk_time = 1.5   # 1.5 sec press for ~1.5m movement

def get_hmd_pose(vr_system):
    """Retrieve the headset's position and rotation from SteamVR."""
    poses = openvr.TrackedDevicePose_t * openvr.k_unMaxTrackedDeviceCount
    tracked_device_poses = poses()
   
    vr_system.getDeviceToAbsoluteTrackingPose(openvr.TrackingUniverseStanding, 0, tracked_device_poses)

    hmd_index = openvr.k_unTrackedDeviceIndex_Hmd
    hmd_pose = tracked_device_poses[hmd_index]

    if hmd_pose.bPoseIsValid:
        matrix = hmd_pose.mDeviceToAbsoluteTracking
        x = matrix[0][3]  # Left/Right position
        y = matrix[2][3]  # Forward/Backward position

        # Extract rotation (yaw) from the SteamVR tracking matrix
        yaw = math.atan2(matrix[0][2], matrix[2][2])  # Yaw angle in radians

        return x, y, yaw
    return None, None, None

For me everything was fixed by emptying folder (prior backup) “C:\ProgramData\Animation Labs\vorpX” and then reinstalling vorpx.

I dont know why this is more mentioned to an extend almost like trying to hide it, or not being aware of it. I know its perhaps maybe related to config factory reset, but maybe not the same.

Uninstalling and you have to install also license.

Prior i thought it only worked only first minutes after restarting a pc, but then even that stopped to work, so i was trying any combination of these

”
headset connected via virtual desktop, also steam sometimes

running vorpx as admin,

alongside vorpx running it with default hook, with alternative hook, with hook helper whoch overrides both default and alternative hook

” but nothing helped only ultimately deleting that folder

[Farutos]

Perhaps late to the party, but you can try playing via remote streaming like Shadow cloud pc, or just pure parsec, vorpx can quite correctly hook on those remote streaming apps, and while experience might not be as immersive as vorpx directly to game, i think still quite enjoyable, and there is no chance this way sea of thieves or any game will be able to ban player for vorpx this way.

[Farutos]

Thankss for suggestion, however i tried nalo and it works quite awkwardly, it works seldomly but when it does, its very cumbersome, the display is literally shaking since it register movement as humping from side to side, so basically while moreless i walk slowly i have to move by hands quickly or even when i move hands quickly the depiction of display is as i was running swinging drunk from side to side on a ship during a strom at ocean, the image of screen is shaking too much. Maybe its better with a phone or tracker mounted to leg.

Furthermore hardware stuff like htc trackers not sure if supposed to be at place like kat loco need bases to track i think so you cant leave the room. If natural locomotion app could be due similar reason not supposed to be walking with it really but staying in place.
Kat loco not sure if those need bases, but perhaps are slower, can be used only at place, and cannot be used like fbt full body tracking or tracking real world objects.

Thanks for your suggested cyberhoes or walkovr perhaps could be better. I think there are some special trackers even for 50 euroes

[Farutos]

and another question, maybe also odd, but since quest headset or at least some or multiple headset can figure out movement, positions that you are close to boundary, and even project to direct vr games, why vorpx cannot make use of this data?

[Farutos]

and basically why catwalk c and virtuix omni can translate movement into arrow keys, but headset/vorpx cannot?

[Farutos]

do treadmills like catwalk c or virtuix omni solving it by merely translating movements into arrow keys? If they can to that, the tredmilless. Why not vorpx, am i missing something whats the difference?

[Farutos]

where can i find and download profile for this game? Can be physical vr walking movement translated into in game moving?

[Farutos]

where can i find and download profile for this game?

Support of VORPX missing, therefore misses opportunity to be used at basically all other non-vr games
Support of VORPX missing, therefore misses opportunity to be used at basically all other non-vr games.

Vorpx tool provides ways of using any game in virtual reality, could be OVRDrop made in a way, that it would be displayed also over VORPX game overlay for example in GTA5?

I started also thread at VORPX site here – https://www.vorpx.com/forums/topic/ovrdrop-overaly-app-doesnt-work-as-in-other-vr-games/

thank you

OVRdrop is powered by SteamVR, and thus can only be seen when SteamVR is running and rendering. vorpX can also be made to run through SteamVR, and thus OVRdrop should be visible in vorpX games when rendering through SteamVR. I have not tested this, but if vorpX is running as a proper SteamVR title, then OVRdrop should be visble and functional.

You will need to set vorpX to run through SteamVR. OVRdrop is only supported by SteamVR at this time, as opposed to something like Oculus Home. OVRdrop works with Oculus Rift and other non-SteamVR-first HMDs, but only when SteamVR is the SDK rendering to the headset. I would be happy to add support for other SDKs when they support the vital functions of OVRdrop, however at this time no other SDK that I know of supports the things OVRdrop needs.

That’s true, thank you, it was due to my Oculus, I uninstalled oculus software maybe unnecessarily , used pimax glasses, and configured in VORPX steam support instead of oculus, and it started to work, although my ovrdrop windows was behind

as since pc games use the same control keyboard, I usually cannot control the game, when different window is activated in windows than the game, and I don’t know if there is any way to overcome this.

Just to say my problems were completely solved by buying a desktop, no matter if optimus technology was directly connected to GPU dedicated port or integrated, it never worked, perhaps because laptop display is always connected to integrated graphics. Who knows maybe if I connected and run a game on external display connected to dedicated hdmi but I had only one hdmi and would not have space remaining to connect virtual reality glasses.
