Inconsistent coloring of Big Render tiles

[JohnQForumPoster]

I've been working on rendering a really high res image via the Big Render feature. It got through about 1/3 of the tiles, which fit together seamlessly in photoshop, but then as of last night, I go to see the tiles that have rendered and they all (every single one) have inconsistent color (one renders the shadows to bright green, another is really dark and low contrast, and a third has huge white grainy splotches all over it that weren't present in the original image. The first 3rd of the tiles are perfect coloring, beautiful quality, and fit together seamlessly. I tried re-rendering the first frame that turned out vastly different and then it gives me a different result, but still not matching the rest of the image. The Big Render project was not modified.

Is this something anyone else has experienced? I've tried color correcting the individual tiles to make them match but the lighting is different in each one so there's nothing that can fix it in post production.

Here's a small image of what I'm dealing with. As you can see it's flawless up until I get to a certain point then every frame has different coloring and the bottom left tile has that really ugly white junk (not in the original render). I re-rendered one of the wrong frames and it's closer, but the specularity is really high and everything has a reddish hue to it, so it still isn't right. I've tried rebooting the software and the computer but no difference. Scale DE is checked and hasn't changed since the start of the project.

This is actually after trying to color correct the offending tiles. It was even further of a difference than that originally.


Any suggestions?
