MultiFunPlayer v1.34.5 - Multi-axis funscript player with SLR & FapTap support

Yoooi · September 15, 2025, 11:19am

Can you screenshot the popup telling you to install .net? Its opened by windows, it should auto download and install the latest .net for you.

Alternatively you can manually install .net desktop runtime x64: Download .NET 9.0 Desktop Runtime (v9.0.9) - Windows x64 Installer

Thanks for the bug report.
I fixed 1.33.9 and reuploaded so just download it again and it should work correctly.

Thanks for the quick fix

squirt · September 15, 2025, 4:51pm

Oh, never mind… Don’t think it’s MFP.

Seems to be something with .NET itself, whenever I open it there’s a notification to repair it. Then it doesn’t repair, then I open MFP and it tells me to install .NET, so I don’t even know.

Yoooi · September 15, 2025, 4:59pm

I never seen .net require a repair so can’t help here. You could try uninstalling and reinstalling.
Also the self-contained version of MFP does not require .net installed so it should work for you.

squirt · September 15, 2025, 6:10pm

Yeah, I think something went horribly wrong somewhere down the line. Oh well, it’s an old burner ACER I use solely for MFP .

Factory reset it, re-download everything, that usually works when all else fails. Thanks for the help and the update

Hi, I’m not sure if this is a bug. I don’t have it completely clear, but there’s something strange: when I’m connected via WEB and I move the browser window (Windows 11) of MFP to one side (to split the desktop into 2 — it also happens with 3 or 4), the video script stops syncing if I change scenes on the page I’m viewing. This does not happen when the window is maximized, only in this split-screen mode.

I’m not sure whether this is related to the browser page (local server) or to MFP itself. However, I don’t see any reason why it should be caused by the local server, since that only serves to pick and play videos, simply adding the name to fetch the script.

This is only info.

Yoooi · September 23, 2025, 8:54pm

I could not reproduce this, I tested with FapTap and it all works correctly when split.
What is hosting the videos/scripts? What do you mean by stops syncing?
I would probably need you to DM me trace logs so I can see what is actually happening.

Hoping someone can help here. I can’t get DeoVR on my Quest 3 to play any scripts anymore. I’m running the SelfContained patreon 1.33.9 version and have tried both DeoVR 15.1 as well as reverting back to 14.6. MFP shows that it is able to connect (green connected) to DeoVR over 23554, but when playing a video, the script preview not only doesn’t show the heatmap, but doesn’t show the white line that marks the progress within the video.

I’m using XBVR as the repository if that matters. Even if it wasn’t able to pull a script, I would expect the white line to move across the progress indicator.

If I use VLC on the same Windows machine, MFP connects and plays as expected, it is just the DeoVR connection to MFP that is the issue.

The Quest 3, XBVR server, and my Windows machine are all on the same network segment. In my Windows firewall, I have allowed all inbound and outbound connections from the IP address of the Quest 3 headset as well as the XBVR server. I’ve cycled remote connections in DeoVR, restarted MFP and the Quest 3 100’s of times, released and renewed IP’s over and over again and just can’t get it to connect anymore. Any help to get this working again would be appreciated.

I’ve turned on trace logging, and here is what I believe is the relevant parts of the application log. In the middle of all the “keep-alive” messages, I’ve tried to play several scripted videos.

Yoooi · September 27, 2025, 2:50pm

For DeoVR+XBVR you should not need any firewall changes.
If that is really the only logs from DeoVRMediaSource then it seems like DeoVR does not send playback information to MFP.

When did it stop working? It’s possible they disabled remote control for some reason like they did with Haptics Connect. Are you logged-in in DeoVR? If yes does you account have SLR subscription or did you buy a script with that account?

You can always try using HereSphere as it also supports XBVR/stash.

paulsy101 · September 27, 2025, 3:04pm

Thanks for your reply! It seemed to stop working around the time SLR went to 15.1 and messed with MFP.

I am logged into SLR, but wasn’t aware of logging into DeoVR, so I’ll try that. I do have an SLR sub with scripts and can’t get it to connect anymore either. That is why I went back to DeoVR 14.6, but still no go. I can’t get MFP to connect to HereSphere on my Quest 3 at all. I need to try and find documentation on how to configure it, because I haven’t found it on my own. Gonna start digging into my XBVR server to see if there is something there. Running 0.4.33 in a docker container and it was working previously.

Yoooi · September 27, 2025, 3:19pm

SLR support was fixed in MFP 1.33.9.
If you are using older MFP maybe try setting SLR username and password to empty so it does not try to log-in. It’s possible that it stops working when you try to use Haptics Connect.

You need to enable timecode server in HereSphere settings.

It’s not XBVR problem, its just that DeoVR does not send any playback information according to your logs.

paulsy101 · September 27, 2025, 3:40pm

I seem to be back working now. I restarted my docker host and container, cleared the script repositories in MFP for XBVR and SLR completely and restarted MFP. Reconfigured the script repositories in MFP and restarted MFP again, and now things are working again as expected. Even SLR! Hopefully everything will continue to work in this state for a while.

I’ve got HereSphere working as a backup now! Thanks for letting me know about the timecode server setting!

Thanks for all your help!

kaiovas · October 1, 2025, 7:57am

Hi there. quick question about the MultiFunPlayer. If the script is perfectly synced, and i have connected via usb cable. have you found a sweet spot for the offset setting? i have it around -10, but i think it is a little behind the movement. Maybe its because i use the pchip interpolation. anyone who have found the perfect sync setting?

stustustustu · October 1, 2025, 1:20pm

I just updated to 1.33.9 but I’m not having much luck, is there any trick to it?

I’ve enabled the new SLR repository and sign into it, DeoVR is connected, Haptics connect is enabled in DeoVR, but when I play a video of SLR no script loads.

Here are some screenshots if you can see something wrong (yes I know all the axis are being bypassed while I was taking the screenshot).

Yoooi · October 1, 2025, 2:01pm

I don’t think there is one. There are too many variables.
I don’t use any offset with HereSphere and have not noticed the need to.

Do you have a “media path modifier” added? Your video path is missing “.mp4” at the end.
Its the button to the right of script repositories.

sleepy4567 · October 1, 2025, 4:53pm

hy

I currently thinking and begin testing linux mint .
Planning to leave windows
Did this program work on linux?

Thanks for all

Yoooi · October 3, 2025, 12:26am

It’s windows only but you might make it work using bottles. Can’t help with that tho.

stustustustu · October 3, 2025, 7:53am

Thanks that was the problem. I don’t recall that turning that on, maybe it was from before there was a Stash repository.

Additional patreon only changelog:

Convert SLR support from Haptics Connect to a script repository

8VTgMkhKmv635×282 14.4 KB

This is initial implementation so there are some drawbacks compared to Haptics Connect:
- It currently does not support script switching, the repository only selects the latest user made script and falls back to latest ai script if it cannot find one. The script switching will come in later MFP versions but it requires big internal changes.
- Heatmap in MFP will load in chunks, but there is a full one visible in DeoVR.
- Only stroke axis works for multi-axis scripts (SLR limitation)
- DeoVR haptics toggle gestures don’t work since they require Haptics Connect
- Scripts stored on VR headset will not be detected by MFP since they require Haptics Connect
If you had problems with SLR scripts not working on Quest due to firewall/VPN when using the old way then this fixes all of those issues.

Changelog:

Block plugins from accessing secure script resources
Add ability to toggle InPrivate mode in Web source
Add ability to export/import (copy/paste) shortcuts and shortcut actions (#195)

So, the last build available on Github is almost a year old now (v1.31.3). But i see this is still getting constant updates on Patreon (v1.33.10). Is this intentional? Every update post keeps saying this is a “timed” exclusive but how long does “timed” mean in this case?

I haven’t used the tool in a long while, just now came back to update it since i got a new machine and i noticed this. Is the new business model to hide all development from the public? Or is there a separate place to download from now? I’m not sure I understand.
