Glad to hear I’m not the only one! I’m currently working in 4.9 with various HMDs
It seems like what we need is a positional override which is independent of the controller. The main issue I run into - the camera, character, and player controller cannot receive extra input reliably, but there has to be some workaround. It is possible to change the camera’s orientation with the player controller. Move the mouse to the left or right and so does the camera. I guess the goal is to read the world rotation of the HMD camera, and then offset the controller to match a target direction. Although, the character blueprint is a little difficult to work with because the HMD has influence over many of its components.
The problem doesn’t seem specific to the HMD hardware. I’ve had these issues with Oculus DK2 and Crescent Bay 3. I received a Vive dev kit yesterday, so hopefully in a few days I’ll have a better idea if it is easier to control. I think its going to suffer the same issues. I have a feeling we have everything we need to get the job done already but I have run out of ideas. haha
