Morrowrift - Morrowind VR (CV1/1.3 alpha! v. 3.0.2)

Level 4
6/6/16 - I finally rewrote the OP... editing this literally gave me a migraine but it's finally cleaned up! If you want to look at the old one for some reason, I archived it here
*ahem* anyway.

- Tested with Disk (GOTY) and Steam copies-- should theoretically work with other versions like the GOG version but this is untested (if someone can confirm that it works I'll remove this disclaimer)

This is a program that hooks into Morrowind + MGE 3.8.0 and, with certain settings disabled, adds fully playable (except character creation) support for the Oculus Rift.
This is different from configurations for vireio and vorpx because it actually decouples the view from the menu and draws the menu as a 3D projection, meaning you can look around separately from where you're aiming and lean forward to zoom in on game text, and it automatically levels your view pitch so you can play it standing up without getting dizzy.
It's written from scratch in C, so there are no dependencies other than Morrowind + MGE 3.8.0 and the Oculus Runtimes.
Here's a badly recorded gameplay video showing off the features (and bugs) in the already-out-of-date version 3.0 (one of the bugs in the video is already fixed!)
(NOTE: if somebody with a decent GPU and recording program wants to take a video of their game window running the latest version of Morrowrift, I'll put it here-- right now all my videos are laggy and ugly because my GPU is old and I don't know how to use OBS)

WHY 3.x?
You might be wondering how this is version 3 when it's so basic... short answer: this one is (theoretically) way more stable and optimized than before due to it using an entirely different structure and coding scheme. Long answer: the first one was DK1 only and was a direct fork of MGE, meaning you had to actually replace MGE with my DLL. Version 2 added DK2 support, and was an extra layer on top of MGE that worked the same way-- that is, by pretending to be DirectX. This version is a standalone program that injects a DLL directly into Morrowind much like VorpX or Vireio, except this program is specifically made for Morrowind/MGE and doesn't have any other dependencies.

There are still a multitude of bugs present in this version, some of which were even fixed in an older version, but as I've abstracted the code more and more in an attempt to make my edits more portable to other games, certain things got harder to fix. Here's a list of all known bugs that I can think of right now:

  • Overlay ZOrder Bug - Any game overlays (or at least steam) come up behind the main menu or HUD. If you're playing with a steam controller and you can't move the mouse on the main menu, try pressing Shift+Tab to see if you accidentally invisibly opened the steam overlay. Luckily it's completely usable in-game since the menu is transparent there.
  • Native Aspect Loss - The game is currently forced into a Rift-shaped aspect ratio, which applies to in-game menus too. I'd like it to obey the game's starting aspect ratio when it comes to drawing in-game menus eventually but that might not be possible if I want the mirror window to show both viewports correctly.
  • Race Selection Bug - The race selection menu is effectively unusable-- I recommend creating your character outside of VR mode and then running Morrowrift afterward and loading a save.
  • NPC Shadow Bug - You have to set Real-Time Shadows to None in-game or else NPC's will flicker like a banned pokemon episode if you're not staring straight at them. I think they use their own clipping planes and I'll have to locate those to transform them.
  • Weapon Clipping - Weapon/hand models have messed up clipping. Probably a similar cause as above.
  • Water Clipping - Water sometimes disappears when you're not aiming at it, and also looks pretty terrible with reflections and shaders turned off which is still required for the hack to work. Also, if you have Pixel Shaders turned on, water reflections don't look right and sometimes draws twice with incorrect headtracking.
  • Sky Movement - Positional headtracking affects clouds and stuff in the sky, which isn't really that big of a deal but looks stupid and can be a bit disorienting if you try to breakdance ingame (or anything else requiring a lot of positional movement). Also, the sun is rotated based on player aim instead of camera position.
  • Loading Freeze - Since the game renders the progress bar during frozen loading screens, the background freezes but still moves with your head which feels really weird. I honestly have no idea how to fix this.
  • Tracking Asymptotes - If you're looking straight up or down, the headtracking gets pretty weird and overdoes roll. This is because of some really old code I wrote back when I didn't understand quaternions, I'll fix it eventually.
  • Elusive Crosshair - The in-game crosshair is hard to see on most backgrounds, and since headtracking is decoupled from the menu it's easy to lose it. In the future I'll probably add a custom crosshair that renders on top of it and is easier to see.
  • Annoying Menu Placement - Not exactly a bug but a side effect of view auto-levelling still transforming the menu so the crosshair lines up correctly: if you're trying to loot something on the ground the menu will come up down there, which is a pain to read or use and also suffers from the trackign asymptote bug. In the future I'll probably fix this by leaving the game menu level and only transforming the aforementioned extra crosshair and weapon model based on in-game aim. I'm also planning on implementing a system eventually where recentering the view actually moves the crosshair to where you're looking, instead of the other way around, which will make it easier to find it.

Even aside from all that, I'm not 100% sure how well this will run on varying systems, so until a few people test it and confirm that it works, it'll be an alpha. Once enough people are able to run it (which may entail some bugfixing) and I improve the launcher a bit, I'll call it a Beta again.

You can download 3.0.2 Here-- Google was yelling at me for uploading an EXE or something so I had to encrypt it so it wouldn't try to scan it. The password is simply "uh" because that was my reaction to Google taking my first upload down. (Just ask this scientician)

If you have a DK2 and you'd rather run the old unstable 0.8 version for some reason, you can still get it Here. There are instructions for using it somewhere in this old archived post.

I recommend starting with vanilla morrowind (goty is fine) since I don't know how different mods (especially MGE and MWSE mods) will affect this. Once you've got it working you can start adding things in and making sure they don't break it.
The first thing you'll need to do is install and set up MGE 3.8.0.
Eventually I want to try to add support for MGE XE and some of the more popular shader mods, but that's a long way off.
Make sure your game has this message in the top left corner before proceeding.
If you're running the Steam copy of the game you'll need to set Morrowind.exe, Morrowind Launcher.exe, and MGEgui.exe to all run as Administrator before this will work.
Next, since this version is still a bit finicky, you have to make sure you run it with the right settings or it will probably just sit there and not draw anything, or render everything totally wrong. Unless you want your game to look that way (or like nothing), you'll need to disable the following MGE features in MGEgui:

  • Distant Land
  • Anti-Aliasing
  • Probably any mods adding shaders

I'm working on getting these features supported but it's very very difficult to do unless I actually modify MGE, and I'm trying to avoid doing that in this version in anticipation of someday retrofitting other games (yes, including skyrim) that don't have open source graphics extenders that I can just rewrite. That's the only reason the ancient DK1 beta version seen on my youtube channel had Distant Land-- I actually modified MGE to add support for it.
If the font size is too small for you, you can choose a lower resolution like 1024x768 and the in-game text will be bigger, but you may get extra aliasing if you do that. Some resolutions render incorrectly right now though like 1600x960.

Just make sure Morrowrift.exe and Morrowrift.dll are in the folder with Morrowind, and run Morrowrift.exe (not Morrowind or Morrowind Launcher). If you're running a Steam copy of the game, you need to make sure Morrowrift.exe is set to Run as Administrator.
If you need the Steam Overlay for any reason (for instance if you use a Steam Controller) You should be able to add Morrowrift.exe to steam as a non-steam game too and still have steam inject its overlay, and if you want to do it with an actual Steam copy of the game you may have to Steam itself as Administrator before it will let you do this (and you still have to add Morrowrift as a non-steam game and run it that way). This may not work for everyone but I was able to run both steam and non-steam copies of Morrowind with Rift support and Overlay support simultaneously.
One caveat with the Steam Overlay though-- for some reason it draws underneath the Morrowind menu right now, so if you accidentally open it on the main menu or during a cinematic, you won't be able to see it. If you can't move the mouse on the main menu try hitting Shift+Tab and see if steam overlay was open invisibly behind the menu.

If you run Morrowrift.exe with -nolevel you can disable the auto pitch levelling, but I don't really recommend it since it can make you dizzy. However if you absolutely cannot stand the menu moving up and down all the time when you aim independent of your head position, this feature can be disabled.

This is currently the only command line argument but I'll probably add more options as time goes on, depending on what needs to be customized.

If you love my project and want to throw in some motivation for me to continue to add new features, new hardware support, and maybe even new games someday, you could make a Paypal Donation and give me a great excuse to work on this project instead of other stuff ๐Ÿ˜›

First things first, I need to fix bugs. If I can get distant land, anti-aliasing, shaders, and MGE XE working well, I'll consider it a major, major victory. Once I have at least MGE working perfectly I may also try to tackle Oblivion and Skyrim support alongside of MGE XE, since they'll have similar shader setups. MGE XE has the benefit of being open source so I can actually look directly at how it works, which may help me structure the code so it works with newer games.
As a side goal, I'd also like to implement SteamVR support instead of just Oculus support to my codebase. Right now I'm saving up for a GTX 1070 and HTC Vive so I can do this, so that's probably what any donation money will go towards. My current GPU is an old GTX 770 which can barely even run things on the DK2, so if I'm going to get a Vive which has no Async Timewarp I'll definitely need a better GPU to go with it.
If I do get a Vive, another pie in the sky goal would be to hack the game so much that your hands and weapon are drawn based on motion controls, and one of the four weapon moves is performed depending on how you move your hands. This would be so insanely awesome I'm kind of afraid to even mention that I'm planning to try it, since it's probably nearly impossible, but hey, I can dream.

I just bought it on sale. Looking forward to this:)

Level 2
Just stumbled onto this and thought I'd say congrats - this is the way rift support should be hacked into games, not the slaving the rift to the mouse as we see on commercial products. Looking forward to this when I get my rift.

Level 4
Hope the beta dll is still working for everybody. I'm afraid it's the best I can do for a while, I've had a really busy summer with lots of work and dealing with lots of illness too... I'm probably just going to give up on the d3d9 master dll because it's just too much trouble getting it to work with multiple games... if I do anything I'll probably fix the crosshair bug since that's the main thing getting in the way of gameplay right now, and try to have a setting for vertical aim to be only via headtracking, or something. I might also hack oblivion or skyrim individually in the future but really my enthusiasm for oculus has died down greatly due to the facebook purchase making a dent in the community and the fact that my DK1 is now outdated and old, and I have important irl stuff I need to do to make a living and pay for school and stuff, so unpaid hobbies have to take a back seat. The other reason I don't work on it often is I switched to Linux, and ofc wine can't handle MGE. I'm planning on getting some sort of virtualized windows os up and running at some point though so maybe it will work in there.

Awesome to hear, looking forward for that. And yeah, the dll is still working for me.

Like people have said, this is the way old games should handle the Rift support and you've done a perfect job. But still, it's just video games and entertainment. Getting your irl stuff in order is more important and there's still a long time before the consumer version hits so no need stress yourself with these Rift projects.

Level 3
I just wanna say, you truly are a hero. It's like you jumped into my brain and picked out all the little things I look forward to in a VR injection mod for a non-VR game. Really, amazing work superllama. I don't have a Rift myself but I just wanted you to know how much I appreciate the work you're doing here.

Thanks, I appreciate your support. I've always felt that non-VR games should work as if the original game is still intact but is being played on a giant 3D screen that wraps around your entire room-- which is the feeling I tried to achieve with morrowrift. I really wish I had the time and drive to make it work even better, or to hack other games the same way, but it's unfortunately not worth the effort at this point in my life, especially with my old DK1-- if I had a DK2 I could add positional tracking support and stuff too-- I just can't imagine how epic that would be to be able to lean closer to the HUD to read it, and also to peek around corners, not to mention the better resolution and display... but alas, 'tis but a fantasy...

Level 3
Any chance of getting the source code for the work you've already completed? I just got my DK2 and I'm dying to play Morrowind with it and this seems like a fun thing to fiddle around with. Way over my head, but I shall fiddle nonetheless.

Level 2
I was a bit bored and took another look at this. I got a good idea: I could edit Morrowinds files and see if I'd find options for mouse sensitivities. Turns out it was a bit harder, I had to go to regedit but there I found the Mouse Sensitivity values. Good thing was that it's only for Vertical movement, there was another value for "Horizontal Sensitivity".
So I changed the vertical value to 0 and it worked! I could play Morrowrift and move my mouse as much as I want and the view can be changed vertically only with the Rift.

But then I noticed that I can't pick anything up unless it's on my eye-level ๐Ÿ˜„

Hopefully 2015 is a good year for VR

Level 3
This was a great idea, too bad it kinda died... I can't get the beta dll to work with the DK2 ๐Ÿ˜ž

Level 2
I got this to work with the DK2. You have to make the resolution 948x1080 and make the oculus the primary display. Now my only problem is head tracking doesn't work. I'm begging one of you to find or make a DK2 headtracking support for morrowind. I will love you forever
