I’m creating a custom profile for the game Gal’Gun Double Peace. (It’s a weeb game). The main challenge with this game is that it’s a shooter on rails. I know I know ‘Why do I even want to play this in VR?’ and all that, but I really want to. I created a new profile based on the Unreal Engine 3 Profile (Because this game is made in UE3), fixed FOV and Geometry 3D first. So far so good. Then I turn on all head trtacking settings to allow Vorpx to let me move the camera with my headset even tho the game doesn’t allow you to move the camera at all. It worked for the most part:
– I can walk to the left and to the right and the camera works properly.
– I can move down (crouch) and up and the camera works properly.
– I can walk forward and backwards and the camera follows properly.
– I can rotate my head in the roll direction (Move my ear closer to my shoulder) and it works properly
– Rotating my head to the left and to the right does NOTHING (Camera keeps pointing forward in the game).
– Rotating my head up and down does NOTHING (Camera keeps pointing forward as well)I feel like I’m so close but I couldn’t find settings to fix the 2 rotation axiss I’m missing. I googled online and it seems that there are aditional settings under “Expert Settings” so I turned it on but no new settings appeared. I also turned on the G3D Shader thing and it also does nothing (I pressed SHIFT END like the tutorial said). It also seems to be ignoring the “Show did you know hints at start” because it keeps showing me the start screen every time I open the game.
I did need to use “Use alternative hooking method for vorpX to hook to the game properly.
Why can’t I see the expert settings? Please Help!
The expert settings toggle just affects a handful of settings in the vorpX menu and the config app that can severely break stuff if used unwisely. They are definitely visible when you checked the box in the config app. If you want to be extra sure you can check whether after clicking ‘More 3D Settings’ with G3D enabled you have a settings named “Focal Offset”. That’s one of the extra settings.
As far as your actual issue is concerned: that’s fairly weird, with default settings head yaw/pitch is what should always work before anything else. Check these things:
- The game must let you look around with the mouse.
- On the head tracking page in the vorpX menu head tracking must be on and sensitivity must be > 0
- If you use a gamepad, for many games the ‘XBox Gamepad Override’ option must be on. Why? A lot of games can’t handle simultaneous mouse/gamepad input. If you want to play such games with your gamepad and mouse emulation head tracking, you need the override, which enabels a built-in gamepad > mouse/kb mapper.
I’m definately not seeing a “Focal Offset” option so I do believe it’s not turning on expert settings for some reason. This are the settings I see:
MAYBE RELEVANT INFO: My headset is an Oculus Rift S. The base profile is the base UE3 profile. I had to check “use alternative hooking method” for vorpx to attatch correctly to the game.
NOTE: The game DOES NOT support looking arround with mouse and keyboard/gamepad, it’s a fixed camera, that’s the limitation I want to solve. Since translation is working even tho the game also doesn’t let you move (You basically just move the gun with a fixed camera) I thought maybe it’s possible with yaw/pitch as well? I know things will break and stuff and that’s okay, I’m ready to vomit or hold my head in one location if I need to I don’t mind. I’m determined to make it work if at all possible, I’m ready to fail if not.
So is there an expert setting I can use for this similar to how translation was achieved? And also what about the expert settings not working, why could that be? Thank you for the assistance!
vorpX’s default head tracking emulates a mouse or a gamepad (if configured that way). There aren’t any settings in the vorpX menu, expert or not, that let you enable head rotation for a game with a fixed camera. With a fixed camera not even vorpX’s DirectVR memory scanner would be able to find the camera.
With G3D you have a little bit if wiggle room for positional tracking as you noticed, but there is no way to do that for rotation since the geometry has already been clipped, i.e. you would look into a black void when rotating your head if head rotation was applied at that point.
If you happen to be a somewhat experienced coder, you *might* be able to code a mod/plugin for the game and use the vorpX C API to apply head tracking to the game’s camera directly (details in the vorpX help under ‘C API for modders and developers’). Provided the game is moddable that’s the only realistic option for your fixed camera game.
Damn, I see. I was aware that culling and geometry would be locked at that point, my plan was to mostly see forward for the mayority of the time, but I wanted a bit of yaw/pitch freedom just for a bit of a more natural feeling, so that would have been good enough as well.
I am a C++ programmer, I might look into modding the game.
That said, it’s still a mystery why the expert settings don’t show… any idea what could be happening?
Thanks for the quick support so far!
