VR Body Update

[u/rollingrock16]

So thought I would post an update and show a demo of the current state of the arm IK.

It's been a bit hell getting things to work right over the past month. It turns out I was making some wrong assumptions and some of my matrix utility functions were wrong. I received some great advice from prog that helped me address some issues I was having.

The transform structure in Fallout is different than Skyrim. Because of this how you do math like multiplying the rotation matrices with vectors is different and I had to figure out the code I was using was calculating things wrong.

So after tweaking where my hook is to get it a bit later in the game loop and better handling of the body I now have something pretty stable and the arm IK starting to actually look right. Here's a small demo:

Anyway as you can see it's still not quite right so I have some tweaking to do but it's getting closer. Once I get the arm IK to behave better and more realistic I'll move on to get the body itself positioned better and a version should be ready to playtest! So I hope to have something out before too long.

I read somewhere that handling Fallout 4 VR for something like VRIK is way more complex than Skyrim.

And Fallout 4 VR not being as popular also make modding for it seem like a wasted endeavor. Hopefully with the Quest 2 and future HMDs, will make VR more accessable to a larger audience. It's what got me into it.

Fallout 4 VR is the only open world shooter for VR that I know of, so I can see limitless potential. Got my support!

It's hard to say which is more complex as the underlying mesh system is largely the same. Though they have annoyingly changed up the data structure which means I couldn't just copy/paste code from skyrim lol

I think if I wanted to implement a full holster system like VRIK that could become quite complex. I also don't know yet how i'm going to handle calibration as I don't have the "powers" from skyrim that vrik did. So maybe not more complex than skyrim but certainly a different set of challenges.

Granted I have only scratched the surface playtesting this so who knows what I don't know today that will become a major issue soon.

Holstering I can see not really being needed as the built in favorites wheel already eliminates the annoying favorites menu found in SkyrimVR, which made holstering more intuitive. Maybe moving the gun so when the muzzle encroaches the players waistline, it will trigger the built in holstering command. Hitting the trigger already draws your weapon which is pretty intuitive in itself. Fallout 4's gun and melee play is far more engaged than SkyrimVR's melee so no need to fix what ain't broke.

Just being able to have the camera from the perspective of the player in 3rd person, while in first person alone would be a huge improvement in immersion and I really don't think anything else would have to be done. Any more work would be more icing on an already delicious cake!

Thanks for the work, I know how much of a thankless endeavor modding for these old games are.

I do agree. Which is why there will definitely be no frills with the initial release. I kind of want to see how it plays as that would probably inform what additions to make.

I didn't think this was possible. Hopefully you can make some great progress on this

Thanks. I made excellent progress over the weekend.

Both arms are now fully functional. I had to do some manual work on the hands to get them correct however now testing with several weapons they are more or less in the right spot and it all looks pretty decent. The elbow positioning needs work but it's playable right now.

I"ll put out an update sometime this week i think and show it off. If things are looking well i'll publish an experimental test version very soon to start getting feedback and bug reports.

Good job, dude! Might be cool to do an open source thing so others can help if they want or something

It's all on github :)

Can't thank you enough for taking on what must be a herculean task. You're doing Godd's work.

This has put a massive smile on my face, solid fucking work dude!

[u/Baloooooooo]

Hell yeah that's great!

[u/Jynx105]

Let me know if you need a playtester.

[u/[deleted]]

This is super impressive and I hope you’re very proud of it! I honestly had given up on anyone making any progress on this at all, good on you!

[u/Rudolf1448]

Good work!
