Just a heads up: the light mask for the science packs can be seen on top of underground belts and loaders at night. Otherwise, this looks awesome. Great idea for a mod!

edit: I think this happens with splitters as well but it's less obvious.

Hey,
this "problem" have classic items too. Example "Nuclear fuel".

I hope that Factorio team fix it, only then I can fix it.

Oh huh, I never noticed that with nuclear fuel. If there's not already a bug report on the forums for that I can make one. Thanks for the reply!

edit: Yep, it's already there: https://forums.factorio.com/viewtopic.php?f=58&t=91843&p=524278
