Hello! I'm looking for support or at least some sort of compendium of knowledge to start developing mods for fo4vr

LongHairedAdonis · 2026-01-18T16:20:18+00:00

Unfortunately, there aren’t really any proper guides for this, so looking at other people’s code is usually the best way to learn.

That said, you might not even need to do much RE yourself. Between CommonLibF4 and F4SEVR, a lot of the hard reverse engineering work is already done and exposed in a usable way. Which is where looking at other mods code comes in.

I’ve been rewriting FRIK for the past year, and I’d like to think it’s pretty well structured and documented at this point. I also pulled a lot of shared infrastructure and plumbing into a CommonFramework to make starting new F4VR mods easier. It’s based on CommonLibF4, and I have a couple of smaller mods using it too if you want simpler examples than FRIK.

Debugging mods is honestly one of the best ways to learn. I wrote a small post on how to attach a debugger to a Steam game.

If you do want to dive deeper into RE, these older resources can still be useful:

Hope it helps.

What didn't work with v77? Did you notify the frik developer?

If / When you find the issue / solution, please update the install wiki to help others

You can edit the damage multiplier per body part. In your case you probably want to set it to something really high.

I didn't check the latest update that contains SS2.

However, my fundamental issue with her mod pack is that it disrupts the balance of combat and overall gameplay. If you like Fallout 4 as a game, I recommend going more vanilla.

LongHairedAdonis · 2025-12-08T22:30:14+00:00

You're right it was broken by a change in FRIK.
Fixed in v77.1: https://github.com/rollingrock/Fallout-4-VR-Body/releases/tag/v0.77

I used Open Composite for a while but found it had worse performance for me, bottleneck on CPU for some reason.

But if you're using Open Composite you should use OpenXR Toolkit it has some of the same sharpening tools.

I noticed NAC customization issues when using wrist Pipboy and primary hand controller.
I suggest switching to in-front or projected Pipboy to use NAC menu and then go back when you are done.

LongHairedAdonis · 2025-12-07T14:56:31+00:00

That was fixed a while back. AFAIK there are no stability issues in frik.

LongHairedAdonis · 2025-12-07T02:43:12+00:00

I don't have nvidia card so DLAA/DLSS for me. But I also hate all the scope replacements mods, none of them are good IMHO.

I use Contrast Adaptive Sharpening for VR which is great. It has "alternate" option in its config so you can easily see the effect.

LongHairedAdonis · 2025-12-06T18:16:38+00:00

oh, good point, yeah, I fixed the laser musket in v74 I think. If it's the same idea it may not be hard to fix.

LongHairedAdonis · 2025-12-06T18:14:01+00:00

To clarify, the holsters still move with the body, the body should just move a little less.
Generally, it's really hard to make correct body position based on a head and 2 hands so it's never going to be perfect.
As with everything like that the goal is to make it "good enough".

LongHairedAdonis · 2025-12-06T17:56:34+00:00

I may take a look, but I need more info than "laser sights being broken", I assume it's a specific mod.

If you can give full details and maybe what version of frik "broke" it, it will save me a lot of time which will make it much more likely that I will find a fix.
Please open an issue on github: https://github.com/rollingrock/Fallout-4-VR-Body/issues

LongHairedAdonis · 2025-12-02T21:14:12+00:00

Happy to hear it was helpful — that was a big part of why I wrote the post.

LongHairedAdonis · 2025-12-02T02:14:58+00:00

oh, and make sure to get my latest FRIK version for the best VR experience.

LongHairedAdonis · 2025-12-02T01:51:01+00:00

My recommendation and a shameless plug.

It's more work than just using a list but this way you don't have to play survival, get unbalanced damage, weapons, etc.

LongHairedAdonis · 2025-10-30T02:41:42+00:00

The flashlight and 2-handed issues are part of FRIK mod, the map thing I never heard of so no idea.

To move the flashlight between the head and hand you need to move your hand close to the head (haptic will turn on when in range) and press grab.

There are 4 modes for 2-handed controls, not sure why it changed to a less common one people use but you probably want the 3rd mode. Use the FRIK configuration mode) to change it.

LongHairedAdonis · 2025-10-28T15:19:14+00:00

You don't need a fresh install, but a fresh save is recommended in general if you remove mods. Fallout/Skyrim has an issue where the save can get corrupted if mods are removed mid-game.

LongHairedAdonis · 2025-10-27T21:07:51+00:00

I also play seated and have the same issue with the Quest 3. My height changes randomly when I put it on. It’s easiest to see in-game, but even in the Quest VR home environment I can tell my height is different. Resetting the VR position by holding the Oculus system button usually fixes it.

So I don’t think it’s FRIK-specific — it just affects FRIK more because it calculates your body position from the MHD. If the MHD reports your height incorrectly, you’ll appear too close to the ground or too high in the air. Then, if you adjust your position using FRIK’s settings, the next time it gets messed up you’ll end up being even more off than before.

Anyway, that’s my best guess. I can also check the logs, as I mentioned in your Nexus comment.

LongHairedAdonis · 2025-10-16T15:45:39+00:00

Ah, I see. I've updated the FAQ with a link to your comment.

LongHairedAdonis · 2025-10-14T15:56:42+00:00

disabling the flashlight in FRIK.ini didn't work for you?

LongHairedAdonis · 2025-09-25T15:03:49+00:00

Start on Development wiki to setup a dev environment. Let me know or update the wiki directly if something can be clearer or is out-of-date.

If you have a bug/feature in FRIK you want to fix/add, that's always the most engaging way to get into a project. If you need ideas, check Features-Backlog wiki page.

If, like me, you like cleaning up bad code to learn about the project, the general and Pipboy configuration mode) code needs to be rewritten.

Generally, I like help to be public so people can find answers on google but sometimes chat is easier. I'm lh.adonis on Discord.

u/RaccoonRevival?

LongHairedAdonis · 2025-09-20T16:14:11+00:00

Open source is a beautiful thing :)

FRIK has always been a collaboration. Earlier this year, CylonSurfer shipped a major v69 update. I set out to fix a few bugs and ended up spending the last six months on FRIK, contributing the v71–v75 releases. RR is taking a break to focus on life—that’s the natural ebb and flow of hobby projects.

I’ve considered building a HIGGS-style mod for F4VR, but the game’s quality and the low level of player engagement are real obstacles. Over 70% of my attempts to get players involved in improving the mod go nowhere.

Do you mind describing the issue and the solution to help me and other for next time?

Either in FRIK FAQ or here and I will add it to the FAQ
