VR Expansion Plugin

Hi .

I’m running into a issue with using SimpleVRCharacter with an IK plugin I’m using. The plugin apparently uses the actor/capsule forward vector for things like knee pole vector positioning, and SimpleVRCharacter is currently only moving the capsule around according to the HMD transform and not rotating it when moving around in roomscale. is causing the pole vector locations to appear locked to the original yaw orientation for knees with the IK setup. I’m wondering if there is any way with the plugin to also have the capsule yaw rotation aligned with HMD and not just position for room scale movement? I tried adding my own yaw rotation to the actor/capsule via the HMD on tick in blueprint, but it caused a double rotation.

Not without breaking a lot of what epic set up for VR behavior (room scale bounds for one, they will rotate with you then which is incorrect, though I guess they are likely already incorrect for simplechar). Also driving view rotation off of character in a networked environment was not something I felt comfortable doing.

If your IK plugin does not have a variable to expose to drive different elements than I suggest you contact the dev and ask for some, because a closed IK system is not exactly suited to VR (or lots of other uses honestly). Generally any good IK system should allow you to pass in your own Forward vector…which would be the VRForwardVector. Without that, it is incompatible with literally every VR setup currently in use in the engine.

I could maybe add an optional rotate with HMD option, but like I said, I don’t like the concept currently.

How do I update the plugin to the latest version if I already have an older one implemented?

Safe Method, should be hassle free, has more steps

1. MAKE A COPY OF YOUR PROJECT (can’t stress enough, if you don’t have a backup system you do regardless of plugin updates, even just engine updates).

2. Replace the current vr plugin folder with the new one (delete old one first)

3. Delete the intermediate folder for your project

4. Right click on the UProject and Generate Project Files

5. Compile

6. Make any required blueprint changes for things that were changed.

Unsafe method, may have to revert to safe method if the engines reference precompiled files are messed up
