4th Sendificate map preview images

Here are some preview images from the 4th map in the Sendificate series. (Haven’t decided on a name yet.)

It has two tutorial puzzles, one main puzzle and a bit of story development.

Fake volumetric lighting in Portal 2

Last week, someone posted a link to this concept art image on TWP:

I really like the way you can see the beams of light shining down into the room and wondered if this could be made in the game engine, in a way that doesn’t look shitty. Here’s a first attempt:

I made it by creating many layers (but not too many, for performance reasons) of an almost completely transparent texture. Each layer adds a tiny bit of colour to the scene, which gives the effect its volumetric appearance.

The key is to make it very subtle, to the point where viewers might not even notice it conciously. The more it stands out, the more fake it looks.
