Lighting in built project varies across machines

Hello,

I have a really tricky bug I’m stuck with and was hoping someone would be able to please help me.

I have built my project into an exe file for windows 64bit, and everything runs beautifully on my machine, however I have tested it on a few other machines in our office and just one of the scenes has a really bright light in it washing the whole scene out to a yellow colour.

Theoretically we should all have identical set-up machines so i can’t see that it would be a hardware issue, and I have tried copying the file I passed to them from a memory stick and that too still works fine on my machine.

Is this something anyone else has ever come across? Any help would be very much appreciated!
Thanks a lot.

Thank you both for your comments, our graphics cards are the same, but some of the drivers had different versions, it was definitely not a monitor issue as we did a screen capture and it showed up on non-effected machines.

I have sort of solved this now, I found one of my lights in my scene was duplicated which was causing the issue, so I’ve been able to remove one and fix it, but I have no idea why it should only affect some machines!

Thank you for your time though!
