Pink renders - anyone else have this problem?

I have an ongoing issue with Daz 3D animation rendering. The animation will occasionally include several frames of the figure with a pink glow. Anyone else have this issue? Any suggestions on how to fix it? I have had several hours-long renders made nearly worthless due to this issue. I will get as many as a dozen frames with the character pink (buildings or other things seem to be unaffected) in an animation. The frames are usually not together. Help! Mark

I've had a few similar issues, and as I do animations (when I do them) to image series, I have just gone back and re-done the affected frames before (or usually after!) using ImageMagick to create the final animated file.
Another reason why you should avoid rendering directly to AVI. If you render as an image sequence and then composite them together later, you can go back and render only the messed up frames. As to why it's occurring, I couldn't say. It could be anything from surface issues to memory problems, or even an error with the video conversion.
Try rendering as an image sequence and see if the problem persists. If it does, then take refer to the frames which are affected so we can help you isolate the issue.
I've had that a couple of times with still renders too, and had to tweak something to get it to go away. I think it happens with uberSurface, or it may be related to the occasional mis-coloured squares with Deep Shadow Maps, but it's difficult to pin it down.
Thanks to all who responded. I re-rendered to AVI and it looked great. Then I edited it into the composite in PowerDirector 11 and produced it and boom ... there they were again. Always in the same place in the film so they are definitely attached to particular frames. But NOT visible in the original AVI but VISIBLE in the final MPEG4. Odd.
I have sometimes seen this issue when rendering to a single bitmap. Then re-rendered and they went away.
how to render who now this problam
This isn't the issue that the original post was asking about.
Your anti-virus has removed the freeimage.dll file, which is needed by Iray. If you can, restore it from the anti-virus' quarantine or vault, if not uninstall and reinstall Daz Studio; once the file is restored don't let the anti-virus remove it again.
