Ladybug Radiation Inaccurate

why does my radiation analysis show blue between all these red surfaces? surely the blue srf also need to be red. Please help.

Hi @Ayxs I doubt the inaccuracy is due to ladybug. Have you tried having a look at the normal direction of your surfaces? I suspect that if you turn on “back faces” and look at the direction of your surfaces, the ones in blue are flipped. Check this out:

hope this solves it.
