Brigade - brute force game engine

Brigade is in real-time, it’s an engine for video games. It uses path tracing to render the image; instead of rasterisation like every other 3D games.
Brigade uses path tracing, which is an extension to the ray tracing algorithm capable of producing photorealistic images. It traces many rays (samples) per pixel in random directions, and then takes the average value to calculate the final color of each pixel.
Whenever a ray hits a surface, a new ray is traced from that hitpoint in a random direction until the max path depth is reached or until a Russian roulette-like mechanism kills the ray.
This way, path tracing is able to produce effects like diffuse color bleeding, glossy (blurry) reflections, true ambient occlusion, soft shadows, caustics, true depth of field, etc.
It can simulate every known material including participating media like fog, god rays and clouds and materials with sub-surface scattering for example.

Mari 2.0

  • Every channel is now a full, non-destructive, layer stack.
  • Shaders now use layered channels to control every aspect of the surface look including diffuse, displacement and specularity.
  • Fully updated .PSD support means MARI 2.0 works seamlessly with Adobe® Photoshop® and other paint software that reads industry standard .PSD files.
  • All the control and flexibility artists know and love from 2D painting applications is now available in full 3D, directly on the model.
  • Procedural Layers - A powerful procedural engine is built into the heart of the layer stack; offering fluid, GPU accelerated real time procedural noises, patterns, projections and more. Procedural layers mean artists can easily create the look they want, seamlessly blending procedural and painted detail with the same toolkit.
  • Mask groups - In MARI 2.0, rather than a single mask per layer, each layer’s mask is a full layer stack in its own right. Artists can use blending, groups, adjustments and procedurals in their masks for a much more flexible, and non-destructive, workflow.
  • Shared layers - We don’t think artists should have to waste time keeping track of how and where they have reused layers and masks. MARI 2.0 introduces a unique layer concept, shared layers, to ensure that artists can spend more time painting. A shared layer is one that appears multiple times in the same stack, or is shared between stacks, and is automatically and instantly updated wherever it is used.
  • Streamlined layer view - With powerful grouping, tagging and filtering options, the layer view in MARI 2.0 means even highly complex stacks are easy to navigate and control.
