Grab Screen Color node in VR is messed up

[yohann1172]

When I use a shader w the Grab Screen Color node in VR (multi pass rendering), the sense of depth is really messed up. When I use Single Pass rendering, the object is only rendered correctly in one eye and the other is dark grey. Is there a way to get the Grab Screen Node to work correctly in VR for both single and multi rendering passes?

Hello,

Thank you for reporting the problem, we really appreciate it. We will have to run a few tests on our side but I suspect that this could be a Unity related issue, with a few alterations we might be able to help.

Which Unity version are you currently using?
Could you share a sample or a few screenshots of the problems present with both modes?

Thanks!

Hi, thanks for the reply. It actually may be physically accurate in multipass, but it feels very weird in VR...like the convergence is off. Maybe this is how refacted glass actually feels and I never noticed. But single pass is obviously not working (see attachment...be sure to click the image to see the whole thing). Any suggestions?

Thank you for the additional information, we will let you know as soon as we have any updates.

OK thanks. In the mean time, do you have any suggested hacks? Unity offers some advice on this topic at https://docs.unity3d.com/Manual/SinglePassStereoRendering.html but I don't know enough about shader programming for this to be useful.

No problem, happy to help. No tips for now, I will have to get back to you as soon as the ASE developer corrects the issue.

Thank you for the link, we are aware of the problem.

Ok, I look forward to a fix. Thanks for an otherwise excellent product and fast responses. Y'all are great.

Thank you for your support, and your patience, we really appreciate it. We added a fix to the latest update (available via our download page) that could help resolve the issue, please test it on your side.

1. Import the package.
2. Open your shader and hit save to compile it using the updated node.

Looking forward to your feedback.

Hi thanks for the response. The results are different w v100_003 but unfortunately still broken (see attached). The right eye is still not rendering the effect at all, but now the left eye is weirder: now the rippled shape moves wildly as I turn my head. Hope this info helps. Let me know if you need me to test anything else.

I will keep you posted.
