top half of the view is black

[ronceray]

Awesome project. Works perfectly for me... except that it uses only the bottom half of the oculus screen, the rest is black, which is very annoying. By moving around my head I can see that the whole scene is there and working, this is the only issue. Any idea how to fix it?

My specs:
Windows 10 on a brand new Alienware laptop with GTX 1070
Blender v78
Oculus Rift consumer version

Unfortunately, this is somehow a persistent issue. I have tried it on 4
different PCs and a SMI laptop. I am still using my DK2 for the same reason.
But apparently there have been people getting rid of the ribbon by tweaking
their graphic card driver and configuration.
Please let me know if you found the solution.

Ow... Too bad. Do you have anything more specific than "tweaking their graphic card driver and configuration"? I'm no developer...

[ptabriz]

I am pretty sure It was on the previous discussion on this page. I tried
the addon on several systems. I also, updated my graphic card and followed
some of the workaround discussed. No luck ;( !

Indeed this is discussed here:
#25
I will try. Thanks Payam.

Please let me know if you figured it out.

Hi!
So, I've been trying... without success so far. As before, a black ribbon (more 2/3 of the display than the 1/3rd mentioned before) obstructs my view. Updating the Nvidia drivers didn't fix it.
One important remark though: when I change the size of the blender window (on my main screen of course), the visible part on the headset changes. Very weird, I guess this qualifies as a bug... So, by putting my window fullscreen with maximum resolution I'm "maximizing" the HMD display use (but with 1920x1080 there's still half of it missing). While if I shrink the window to half of this in height almost nothing remains in the headset.
As it is, the problem isn't fixed for me as I cannot go over 1080px in height. If I could, I'd try to connect this to a UHD screen and see if it improves this... Any workaround for increasing the (apparent) screen resolution above that of the hardware in windows 10?
But anyway, I think this bug needs fixing. Dalai, any comment on that?

[ronceray]

PS: that's gotta be the dirtiest possible workaround, but by changing my display settings to "portrait" and making blender full screen, I now have a full height view on the display...but now with width problems, as there is a black ribbon on the right of each eye. Slightly more usable than the top ribbon as it is smaller, but still quite crippling...

[ronceray]

Hi! Just a quick update: I'm now trying - without success so far - to identify the part of the code that sets the size of the oculus rendered screen. As it's affected by the size of the blender window (see previous posts) my guess would be that it is initialized somewhere in the operator.py file...where the interface with blender is apparently made. No luck for now though. Could anyone more expert than me give some advice? Thanks!

[michaelybecker]

Nothing useful to contribute here - just moral support:). Getting the same black ribbons on a DK2 / Win10 / GTX1060 - would love to see an update on this! And thanks so much for detailing your workarounds.

[dfelinto]

I will setup a new computer for casual Oculus (DK2) development soon. Let's hope I'm going to run into the same issue you are all facing :)

[michaelybecker]

Looking forward to hearing updates. And thanks for all your great work thus far! AFAIK you're the only one standing up to the challenge:)

[ronceray]

Fingers crossed, Dalai! And same, thanks for the great work. I'm hoping to use this to show my research data at conferences and poster sessions, it's mindblowing... I just hope we could use the full screen ;-)
By the way, one cosmetic suggestion: it would be very nice to add a scale parameter to the VR UI. Most blender files are at a scale way too large to fully appreciate the VR; of course we can scale them down manually, but it would be more natural to be able to choose manually the user scale - to - blender scale ratio.

[ptabriz]

I agree with Michael, I recently compiled a blender with Openhmd. It has considerable limitation and latency issues in compare to your solution.
BTW: Dalai , you are less likely to face issues with DK2 as i have so far implemented it on more than dozens of systems with win10 and various blender builds. The issue with CV1 is consistent though. If you like and dont have access to cv1 i can setup a time to skype in and go over the blender console together remotely.

It would be very nice to add a scale parameter to the VR UI.

If I remember correctly, the scene scale (Blender > Scene > Units) is taken into account. It should at least.

:/ that may be a problem. If that's the case I will try to get someone to lend a CV1 to the Blender Institute. Otherwise we arrange some remote debugging. (it will require MSVC in your end, as well as CMake).

So maybe you'll be able to reproduce with DK2 after all?
