Wooo, double post!

Anyways, I was messing around with Portal 2 commands and found a bunch of commands that I thought might be useful for screenshots (and other things..)

Specifically, mat_bloom.

Anyhow, if you want to make your Portal 2 look great (?) with copious amounts of bloom, here are the commands I used.

mat_motion_blur_falling_intensity 6
mat_motion_blur_percent_of_screen_max 5
mat_motion_blur_strength 5
mat_bloom_scalefactor_scalar 4
mat_bloomscale 1.5
mat_ambient_light_g 0.005
mat_ambient_light_r 0.001
mat_ambient_light_b 0.01

You might want to ditch / reduce the bloom commands but I think that the ambient_light commands make Portal 2 look better (as well as the motion blur, it looks really cool on the intro).

I'm out, goodnight everybody.

To make a Screenshot Look prettier, You can use Image Editing Software. Its not in-game though. But it makes it look much better.
