after waiting what seemed like an eternity to render i finally had my scene lit. but once opening the render it was missing part of the background which showed within cinema 4Ds render sequence. with only a little time left i couldn't render out the scene again so i overlaid the footage with the pre exciting footage witch looked fine until i pressed play. now i have a problem with the render shaken and not being in sync with the footage that was textured into the scene. it was at this point that i noticed 2 of the computers rendered the glow different to the other 3 computers that i rendered on. which was weird being i made no changes to the file when copying over to the other computers. with not much time i tried fix it but was unsuccessful. i had tried stabilisation tracking the background hoping it wouldn't be as noticeable but had no luck, i also tried key-framing the position to sync it up with the background but then that looked even worse. so i just had to leave it and try and make do with what i had as i left it to late to render it out again.
