Hey everyone! I'm trying to do some research into a problem, and I'm curious if anyone else has experienced it and possibly found some solutions. This is with Nuke 6.3v1, on Windows 7x64.
Lately we have been having serious issues with the Nuke viewer when placed into stereo mode. We typically are using the OpenGL mode, but this problem appears to be present even in Anaglyph mode. Essentially what is happening is that Nuke is not properly updating the stereo views as changes are made to nodes. What typically happens is we will be working on a stereo comp (IE multiple stereo pairs merged together) and when making interactive changes to nodes, when the viewer updates it will sometimes just go completely flat. Other times it will redraw only a partial right or left frame. As if that wasn't annoying enough, what makes it even worse is trying to get Nuke to fix itself is often so frustrating you want to punch babies. Even if you completely clear both disk cache and buffers, Nuke stubbornly holds on to the bad image in stereo mode. Often times you end up randomly swapping left/rights in the viewer until it finally wakes up and does its thing. Even MORE odd when this is happening is that sometimes you can temporarily "fix" it by setting like TWO left or two right views in the viewer. Yeah that makes no sense, but it works sometimes. Sometimes the only way to fix it is to restart Nuke. Unfortunately nothing about this is consistent, nor is there one simple way of reproducing it 100% of the time. However it happens extremely often, often resulting in hours of lost work time. While I have not found a workable 100% solution, I have found that pausing the viewer and then doing manual updates makes it less likely to break. Additionally I put together a small forced disk cache gizmo that essentially forces Nuke to always render the current frame to disk when changes are made and then read that rendered frame from disk. When using this it is also a lot less likely to break, but of course this solution is incredibly slow and still not 100% We think this might be new to Nuke 6.3, but are not 100% sure. No one seems to remember it happening before we upgraded, but that doesn't mean it didn't for certain. Our hardware consists of the following, to the best of my knowledge Video Cards: nVidia Quadro FX 5600 nVidia Drivers: 266.45 (I know this isn't the latest, but at the moment we're restricted from upgrading due to other software, so I hope this isn't the problem) If any additional details are required please let me know.
