Somewhat rough but functional VR mod to allow HS2 VR fun.

Credit to killmar-the-3rd for the initial implementation, this builds on his work. https://github.com/killmar-the-3rd/HS2VR Credit for the underlying library (VRGIN) goes to Eusth (https://github.com/Eusth/VRGIN) and Ooetksh for their AI-Shoujo version. The present Honey Select 2 VR mod is based off (https://github.com/Ooetksh/KoikatuVR).

Everything, albeit with some quirks. Main game, Maker and Studio are all playable. The full game experience, only in 3D.

Switch to Standing mode then (def: Ctrl+c, Ctrl+c [dbl tap it]). Alternatively change the DefaultMode in VRSettings.xml.

Turn off TAA. Disable BetterAA (or uninstall it). Switch to SMAA (in Graphics->Post Processing)

Yep. In which case you just need the HS2Graphics zip file. Ignore the other two.

The VR input system actually moves the system mouse pointer. Remove HMD and make sure there isn't another window over the game window (or run game full screen). Probably the pointer has escaped and you are actually clicking into something else.

Turn off MSAA. Turn off Realtime Reflection Probes (in Graphics->Settings). Keep 1 Directional Light with Shadows enabled (you can turn down shadow strength all the way to 0 if you like, just leave shadows enabled). If you don't know what this means, just don't turn off shadows globally or turn off shadows on the Cam light in specific. Turn down/off SSS. Turn down RenderScale (in VRSettings.xml file). Something along a .6 to a .8 should give you a nice little bump in frame rate.

In addition to the usual graphics quality settings, turn up RenderScale (in VRSettings.xml file). Something along 1.2 to 1.4 will look nicely sharper. Note above 1.8 will be a slideshow on best possible current hardware.

Anything that supports SteamVR (OpenVR) should work just fine.

Plugin coexists with the official VR plugin now, you can have them this installed and still use official VR as you wish.

Seated mode works (and is the new default). This mode is VR + mouse/keyboard, controllers not needed. Controls are the same as the 2D game except the UI floats in front of your face. Use the mouse and keyboard to drive. Switch to Standing mode (where the UI is attached to the controllers) by pressing Ctrl+C, Ctrl+C (double tapping ctrl-c). You can change the default mode (and various other stuff) in the VRSettings.xml file in game root.

Maker now functions and has a visible UI.

Major camera improvements for both seated and standing. Basically everything should now work as expected, no more ending up in strange places and facing backwards. Title, lobby, H and dialog scenes will attempt to adjust for the FOV change by moving the camera closer to the girl so she occupies the expected amount of view space (otherwise you feel weirdly far away). Note that the fixed VR FOV causes some camera positions to be a bit amusing (like the 2D view of the ledger books that in 3D has you standing on the counter instead).

Camera buttons in studio now work, as do the in scene movable camera views, though selecting the in scene cameras can be fun since the dropdown is invisible.

Compatibility with POVX plugin: https://github.com/Animal42069/HS2_PovX version 1.2.2(+)

Lock mode, when POVX is engaged pressing lock button (default 'L') will freeze the head updates and lock the POV camera in place. Press L again to release. Handy to avoid some of the shaky-cam jerkiness.

New Standing Mode Tools:

POV Tool (eyeball icon). Available when POVX is.

Gimbal Tool (err, rotatory icon thingy)

Switching modes (Seated to Standing or vice versa) results in an awkward camera height, simply switch scenes or camera views to correct it. It's possible to come out of an HScene or Maker with the view tilted. If that happens switch modes and then switch back (Ctrl+C, Ctrl+C - double tap control c to switch). 3D space studio object manipulation is basically impossible as the raycast source and your eyeballs are now different. You can use the move controller and HS2PE to work around a lot of this, but there are limits. Certain GUI elements in studio have a raycast component that renders them invisible in VR. Specifically the scene settings, camera light and the in-scene camera selection drop down. They are present and actually clickable just not visible. Maniputlation of scene settings will probably need to be done outside of VR unless you have incredible spatial memory. Camera light can be adjusted in Graphics instead. The camera selector drop down isn't too hard to click blind...

While we wait for Hooh to overhaul Graphics and release HoohSelect2Graphics - The Visual Experience, this is a duct-taped copy of HS2Graphics with support for VR. It's equivalent to the HS2Graphics included with Hanmens SSS packs (and supports that functionality) but has various fixes for VR functionality (including SSS skins in VR). It also adds a preset system that allows you to designate a preset for various modes which will be reapplied as the game jumps between scenes. No more need to keep reactivating SSS everytime the scene changes.

This works for 2D and both the official and unofficial VR modes.

Some notes on VR graphics settings:

Since the VR interface is in scene TAA applies to it and tends to make it a bit blurry, probably stick to SMAA in scenes (though I break this guideline all the time...) For best VR performance I recommend turning off MSAA and Realtime Reflection Probes (on Settings) and lowering the SSS settings Postprocess Iterations to 2 and Shader Iterations per pass to 4. Deactivating dither may help, although I didn't notice a big difference.

Note: Be careful with shadows, it might be a quirk of my setup but turning off shadows cuts my frame rate in half. Make sure shadows are on in graphics and in any other mods touching the graphics settings. You need at least one directional light with shadows on in a scene.

Requires HS2DX (will not work with vanilla HS2), BepInEx

Unzip the HS2VR.zip file into your base game directory.

BACKUP YOUR GLOBALGAMEMANAGERS (in HoneySelect2_Data and StudioNEOV2_Data - make a copy of globalgamemanagers somewhere safe)

Either patch the globalgamemanagers in HoneySelect2_Data and StudioNEOV2_Data yourself or use the ones from the release section. MAKE SURE YOUR GAME VERSION MATCHES THE GLOBALGAMEMANAGERS VERSION. As of latest this is for HS2DX V1.2.3 ONLY.

Optionally (but recommended), install the included version of HS2Graphics (same as the latest SSS version of HS2Graphics...but with VR support and related QOL improvements).

to

You can also find a pre-patched globalgamemanagers on discord.

To check that VR is working, start Steam VR and run HoneySelect2.exe with the the option -vrmode "OpenVR". This should show the game in VR, albeit without any UI.

Copy BebInEx and HoneySelect2_Data folders into your game directory. That should deposit HS2VR in BebInEx/plugins and openvr_api.dll in HoneySelect2_Data/Plugins.

If SteamVR is running, the game should start in VR mode. If you need to force the game into non-VR mode while SteamVR is running and don't want to disable the VR mod for whatever reason, pass the --novr command line argument.

The controls follow the VRGIN setup:

The mod currently uses a patched VRGIN.dll from the AI-Shoujo VR mod by Ooetksh, not the included git submodule. Once that version of VRGIN makes it onto github, the repo can be updated to include it.
