Comparing images A/B in History

[stezza]

I seem to get white lines during scrubbing from A to B is this a graphics card issue?

Which build is this? There used to be a similar issue, but it was resolved for recent builds.

Best regards,

This is the latest build from the nightlies.

Ok; which Windows version? What is the resolution of the images?

Best regards,

Windows 7 x64 and the images was 640x480

I was having this issue with nightly 13240, Maya 2009 x64 using winXp64 and a Quadro 3800, not sure of resolution, but I don't think it was above 1920x1080.

Similar problem here, except as well as the divider refresh problem, the display is black after clicking H.

We're now using 13418 with 2009x64/xp64. I thought this issue was just with the A/B feature, but today I discovered the history panel is now broken, which is much more problematic for us. Here I can open it up, and also load renders (vrimages) from an OLD build fine. But as soon as I try to use A/B or load an image rendered in 13418, the VFB display breaks (turns black) and fills with noise if moved between monitors. I also can't send the new build VFB image to the Maya Render View once it breaks, MayaRV just gets a flat dark blue image. Oddly, if I set my A and B images to those rendered with build 12797, the new feature works fine and I can move the white bar around to set the A/B blend point. I also tried installing the latest quadro drivers from Nvidia but that didn't seem to fix the problem.

Thanks for the pointer; will check it out however keep in mind that this feature is still in development.

Same issue here on a winXP 64 with a Quadro FX5800 and yesterday's build.

Also once the comparaison is engaged I cannot stop it. I need to exit Maya.

Hi Vlado,

The old/new build exr thing seems to be a hint. The problem is not that the A/B stuff is still in early development, I'm excited to see this functionality. It's that the history panel, esp. save/load is now broken. I also tested this on the same hardware but in win7x64 and encountered the same problems. Yannick, same here when I enable the comparison I can't disable it, but I can get things to 'come back' if I load a vrimg from an old build.

You can disable it simply by selecting one of the 'A' or 'B' images and clicking on the "Set A" or "Set B" button respectively.

The original problem (saving of images not working) should be fixed now for the next night build.
