Surfaces: Difference between revisions

Portal-able surfaces in ''Portal'' are white plates that seem to be made of some kind of stone. They are easy to tell apart from the dark surfaces where someone cannot shoot a portal at.

Non-portal-able surfaces in ''Portal'' are made out of dark brown/black metal plates that reflect the light slightly. Valve has chosen this design because in opposite to the portal-able surfaces, the darkness and the shininess are good to make out from a distance, as it is said in the Commentary Mode of ''Portal''.

The portal-able surfaces in ''Portal 2'' seem to be the same as in ''Portal'', just a littlebit dirtier. {{spoiler|This could be because [[Aperture Science]] withered in the time between ''Portal'' and ''Portal 2''.}}

The non-portal-able surfaces in ''Portal 2'' have changed however, they don't have any 3D effect or shininess like the ones in ''Portal''. They have remained dark, however.
