Archaica: The Path Of Light

is a visually stunning puzzle game with lasers and mirrors, that enraptures gamers not only with finely designed levels, but also with an interesting storyline. In this game we become the Chosen One from the nation that believes walking the legendary Path of Light will save the world from impending disaster. We revive ancient mechanisms, explore secrets of an ancient civilization, and discover the true destiny of The Path along the way through extraordinary realms.

Key Features

  • An extraordinary atmosphere - We’ve put a lot of work to make Archaica’s world a beautiful and remarkable place. Every single level has it’s unique atmosphere and encourages further exploration.
  • Interesting puzzles - We’ve prototyped hundreds of puzzles but selected only some of them. This ensured puzzles are unique and each of them is based on a separate idea. Additionally there are several mysterious devices occurring only in particular places making them even more unique.
  • Ancient artifacts and secrets - Archaica’s world is full of secrets ready to be revealed: artifacts and devices that help you develop your Totem, mysterious ancient machines and their purpose awaiting to be discovered, and entire secret rounds where hint is not available.


“Archaica is a really fun puzzle game, and very beautiful. Great job guys!”

John Romero, creator of Doom and Quake, link: John Romero on Twitter

“Indie games differ from one country to another. On the other hand examples can be spotted on the west as well as the east where a remarquable game is being created, thanks to massive labour input, by a small group of people joined by craving for 'developing their own game'. Archaica: The Path of Light a puzzle game presented during the gaming event Poznan Game Arena in Poland, is without a doubt an example of this kind of piece of work.”

Here is a short and general description about how the lighting in Archaica is generated.


  1. On all the screens there are transparent and emissive materials (we just didn’t hide them).
  2. Archaica renderer evolved from light-pre pass to more deferred (for performance reasons - less draw calls). There is still option for computing lighting per-material (for example crystals use this).

Final effect

D 02 full scene

At first let’s take a look at indirect diffuse lighting (~ambient)

Every next screen shows another light technique added

Only height ambient (two colors interpolated by height):

01 height ambient only

Shadow color (fake secondary diffuse term). Takes into account scene height and normal (and it’s also colorized):

02 ambient shadow colorsec diff

With SSAO applied:

03 ambient shadowcolor ssao

And the last component: secondary directional light without shadows (fake simulation of the reflected light). So this is the full indirect lighting (diffuse; only secondary light adds something to the specular lighting term):

04 ambient shadow color ssao sec

SSAO alone:

05 ssao

Indirect specular lighting (exaggerated)

Computed as a single fullscreen pass:

06 secspec no mul reflectance

The direct lighting (diffuse and specular)

Direct light without shadows:

B 01 noshadows

Shadows alone:

B 02 shadows

And mixed - full direct lighting:

B 03 direct light

Additionally - full (direct and indirect) diffuse and specular lighting alone:

B 04 only full diffuse

B 05 only full specular

Final Light composition

The final lighting in Archaica:

C 01 full light no bloom

Bloom alone:

C 02 only bloom

Mixed - final lighting and bloom:

C 03 full light

As a curiosity - a final lighting without tonemapping:

C 04 no tonemapping

Final scene

Without fog:

D 01 full scene no fog

FINAL SCENE - with fog and godrays:

D 02 full scene

Additional comparison - Without colorgrading (colorgrading adds only a small correction to final look):

D 03 no colorgrading

And as a bonus - Archaica gbuffer


E 01 diffuse


E 02 gbuf normal


E 03 gbuf depth

Reflectance (exaggerated):

E 04 gbuf reflectance powiekszon


E 04 gbuf roughness

Hope this is useful and interesting :)

Fell free to ask if You are interested in any part of computing the light (and final scene look) in Archaica!
