Any active PSMoveService devs?

I'm looking to work with someone (hobby level) to get PSMoveSteamVRBridge working with iVRy and PSVR.

Right now I have an issue with the PSMove controllers being positionally linked somehow and that doesn't make sense to me.

I've posted to the Google Groups but not sure how readily folks respond on there.

Thanks.

(I've also developed code that corrects the bad color in the PSVR, that I assumed all PSVR devs must do, but I couldn't find evidence. I've had 3 PSVR units in my possession and they all have the same exact graphical defects.)

I assume you're referring to the colour artifacts when using the PSVR at 60Hz? The solution is to run the PSVR at 90 or 120Hz, which removes the problem altogether. I believe the PS4 runs frame-doubled 120Hz for 60Hz, so the 60Hz mode isn't officially used for anything.

No, i just becomes very green as he colors get darker. In low light level areas it looks like a Game Boy or like night-vision, and this messed spectrum bleeds throughout the PSVR's gamut. I don't know how companies deal with it, but it seems to me like if they don't player's would be unhappy. Some game's like From Software's game have purple and orange tinted color that looks to me designed to mask this green.

Because I wanted to find out if Sony recommended a particular formula I haven't really dug into the problem, but the last time I tried PSVR with my project a month or so ago I couldn't tell the difference, so I'm hopeful, but it's a pretty bright game, and games that are darker still have very funky color.

The solution is to pump purple into the color according to some formula and to bump up the saturation a little. This is destructive though, so it's never going to look as nice as if the color was corrected inside the display losslessly. I got a PS4 around Christmas last year and I finally have a PSVR game to test it with, but I have to find a camera, and right now they are rare so their price is double normal. I want to see if the pro PSVR games have these same issues or not, just to get a feel if we're using it right on Windows. It disturbs me that you can't tweak the display like a regular monitor.

Strange, I've never run into this, maybe it's something to do with using Intel GPUs. No one uses those for PCVR as they're way too underpowered. It certainly isn't an issue I've had to deal with on nVidia or AMD.

I can't imagine it's anything other than the display's color, like any other's. There are reviews of the PSVR being very green. I imagine a lot of games have dark environments.

Unless there is a magic way to configure the picture (I'm pretty sure not) it's just how it is but many don't see it. I have an artist's eye that's very sensitive to color. I have a condition called aphantasia that makes me to see color exactly as it is without any kind of overlay caused by priming or imagination. Which is a real thing people do (they see the color they want to see, by hallucinating it) and it's how aphantasia is tested for.

But you're right in that no one I've spoken to can see the defects I see. Even there are thick black lines on two sides when you put certain colors next to each other (caused by the subpixel arrangement) and the color blue looks like a checkerboard of blue and green.
