Unreal Engine: 4.17.2

Internal Version: v0.2.7

Architected for Procedural Generation

  • All game systems are designed to be dynamically-created and configured as-needed at runtime. This ensures that players truly are in charge of their play experience.
  • Items are designed to be procedurally-generated based on a set of statistics, modifiers, and hundreds of small parts that are dynamically-assembled to fit certain visual and functional styles and be completely unique to every player.
  • This is carried through to the huge enemy bosses (Behemoths), environment art, world simulation, and more as well.
volumetric_lighting_test_omg_it_works_debug_02

Physically Accurate Simulations

  • Building off of systems already in Unreal Engine, we created a system and workflow to ensure that there is physically accuracy throughout the worlds we create.
  • This accuracy extends to game systems, physics simulations, as well as rendering. If it looks like wood, it'll behave like wood, sound like wood, break like wood, and... Be... Generally wood-like.

Completely Dynamic, Always

  • Everything we do in our games, we do based on a series of systems and simulations. And then doing everything in our power as gamers to try and see how far we can get with them.
  • To ensure as much customization and variety as possible for our players, we have completely dynamic lighting, global illumination, environment simulation & rendering, materials, and more.
  • We want all of our games and their engine to be procedural, dynamic, flexible, and bulletproof. So we can hand it to our players and say: have at it.
over_voluemetricated

NVIDIA GameWorks Volumetric Lighting

  • A highly-detailed, physically-based atmospherics scattering and volumetric rendering algorithm.
  • Uses existing shadows maps for lights in the scene to construct hardware-tessellated meshes every frame to serve as detailed light shafts that are then rendered with a customizable, powerful shading and scattering effect.
  • Additional work done to work alongside trueSKY for full and seamless integration into our entirely dynamic scene.
kaboom

NVIDIA GameWorks Blast

  • Major improvement to the PhysX and APEX destruction that allows for GPU-based rigidbody simulation.
  • Allow for complex, efficient, dynamic in-game destruction to truly bring the rugged world of Steel Hunters to life.
  • Blast allows us to create content/structures with multiple layers, structural integrity from its miscellaneous pieces, and... Well. It's fast. Yay fast.
blandtown_cloud_and_lighting_pass

Full trueSKY Integration

  • A full, engine-wide integration of simul's trueSKY cloud and atmospherics calculation and rendering middleware.
  • trueSKY allows for complete, physically-accurate atmospherics with a wide variety of customizable parameters for aesthetics and performance.
test_houdini_cityblock_placement_scene

Houdini Engine-Powered

  • Since Joy Machine's middle name is "Dynamic and Procedural" (it really is), SideFX's Houdini is like software made specifically for us. Their increased dedication to making it a game development tool along with the Houdini Engine has made it a perfect tool for our kind of workflow.
  • We'll be talking more about how we use this in our workflow in the future, but the general idea is to create highly-parameterized content packages for run-time variations of miscellaneous meshes.
granite_smaple_tileset

Granite Integration

  • Handles giant texture database files (UDIMs) that support up to 256k worth of textures in a single file.
  • No need to modify any assets with custom UVs, Granite is just integrated into the engine and simply requires some basic material modifications to use a custom texture sampler.
  • Dedicated middleware for texture streaming in-and-out varying levels of detail.
gdc_demo_ai_spiderbots

PopcornFX Integration

  • Joy Machine and PopcornFX  go back a while, ever since Trent established the VFX pipeline on ArtCraft Entertainment's Crowfall around it.
  • More relevant: PopcornFX provides an incredible degree of power and runtime customization for all of its effects, making each effect a very powerful and versatile asset.
  • And our Unreal Engine integration outperforms UE4's Cascade system in most use-cases. So that's pretty excellent as well.

From the Joy Lab

VoxelFarm 3 Integration

  • We've been working with the team at VoxelFarm since it launched, and we also have it fully integrated into our UE 4.15 codebase. Which means: massive terrain, fully-destructive environments. And other things we probably haven't thought of yet.
  • Adaptive meshing, a complex, efficient, dynamic level-of-detail solution, and an entire system built with procedural generation principles at its core allow for: well, anything, really.
hbaoplus_v3_final

NVIDIA GameWorks HBAO+

  • Incredibly detailed, efficient ambient-occlusion.
  • Uses the depth buffer as a height-map to conduct ray-tracing to ensure accurate, detailed AO.
  • With the latest HBAO+ binaries, we were able to replace both methods of AO built-in to UE4 (SSAO and DFAO) and save up to 9-10ms per frame.
  • [Currently Disabled in Favor of UE4's SSAO].

NVIDIA GameWorks Flow

  • A completely dynamic, run-time simulation and rendering solution for fluid-based effect simulations.
  • True volumetric rendering of the results of the fluid simulation, including lighting and shadowing.
  • Renders fire, smoke, and other fluid-based effects in-game efficiently, even without the need for extensive offline computations.
  • We really like fire.
