### Some thoughts about light in general

Posted:

**Thu Jul 18, 2013 10:31 am**I would like to have the current lights to throw shadows when an item is in the way - because they are on the ground.

But shadows is an own theme (e. g. seeing the object-shadows wandering with the sun would be really cool).

And I would like to have the lamps-light behaving more like real lights. Real light-sources behave like 1/r^2 . This means, there is a very lighted point around the source and then the light very fast darkens and then there is a big, dark area around it.

I think in factorio they behave more like 1-r, which means, that the light is descending linearly around the source and at some radius the light disappears...

Also I would like to have a different light-color for the lamps - I think for orange-lights, like in big industry-complexes, or maybe also a very greenish light.
