PS4 Exclusive The Order: 1886 Set to Get Even Better: Developers Talk About Lighting and AI
The gameplay footage shown for The Order: 1886 yesterday was absolutely impressive under many points of view, but today we learn that the game could improve even further between now and its release.
Ready at Dawn Co-Founder Andrea Pessino mentioned today on Twitter that the game’s artificial intelligence is still being worked on, and it will be better “soon:”
The AI is still rough – we have some amazing people working on it, it will get better soon. : )
We also get some information about the already impressive lighting of the game from Graphics and Engine Programmer Matt Pettineo:
Currently using H-basis for lightmaps, SH for probes sampled by dynamics. Were considering switching to SRBFs.
If you’re not into programming, this is probably going to sound like some obscure dead language for you. H-Basis stands for “Hemispherical Basis” light maps, SH is the acronym of “Spherical Harmonic”
Spherical Harmonic lighting is a powerful but a bit obsolete technique to calculate lighting from global illumination sources for a 3D scene in real time. If you want the full rundown, you can find a very through document directly from Sony Computer Entertainment here. Hemispherical basis or hemispherical harmonics lighting is similar and compatible, but has a lower margin of error. Both techniques are also pretty complex.
On the other hand SRBF lighting is mathematically simpler and requires less computational resources, while its visual quality is still the same as the SH and H-basis. A switch to SRBF would probably free up computational resources to be used in other elements of the game.
We’ll have to wait and see just how far Ready at Dawn will be able to push The Order: 1886 before its release, that seems to be slated by the end of this year.
