New Rendering Pipeline

Fully Deferred Rendering

UNIGINE 2 has been switched to a fully deferred renderer, so all opaque geometry is now rendered in the deferred pass. Therefore, the rasterization process happens only once, which highly increases performance. After the rasterization process, all lights are applied to the necessary buffers to create the final image of the scene.

Transparent Objects

Transparent objects rendered in the deferred pass are grouped to be rendered in one DIP, which is much faster than in forward rendering, but there is a limitation: they overlap other transparent objects rendered in the deferred pass. However, they provide realistic reflections and cover most cases.

If it is critical to see another transparent object behind the front one, forward rendering is available for transparent objects. In comparison with the deferred pass, transparent objects aren't grouped in this way, which increases the number of DIPs.

Performance Optimizations

It is important to understand some facts about performance of the new renderer as it has several new features in comparison with the older one. Maximal FPS on empty/simple scenes with the new render is lower (about 200-250 FPS) than the old one (up to 1000 FPS), but anything above 120 FPS (60 Hz in stereo) has no practical difference. The interesting part is when we start adding content into the scene, the new renderer's FPS value is almost constant, very slowly decreasing in comparison with the old version.

A simple test with a lot of small static meshes:

As for the raw polygon rendering performance, UNIGINE 2.0 demonstrates even better results:

Here is another test on a static scene with 7.3 million polygons and multiple LightWorlds without shadows (deferred rendering is better for handling lots of dynamic light sources by design):

So UNIGINE 2.0 performance scales much better and can perfectly do the heavy lifting with CAD data, unoptimized 3D scans or any other extremely complex and detailed scenes. Many customers chose UNIGINE 1 because it outperformed competitors, and now we pushed the performance of the engine even further.

Temporal Anti-Aliasing

UNIGINE 2 uses a high-quality temporal anti-aliasing (TAA) algorithm by default. The obsolete multisample anti-aliasing (MSAA) and all corresponding functions have been removed.

In case of fully deferred rendering (when the final image is composed of different texture buffers: depth, normal, etc.), TAA applies smoothing to the whole scene, which is much faster comparing to MSAA that is applied to each texture buffer. Besides, TAA improves the whole image (not only the edges of the geometry, like MSAA) including geometry, shadows, etc., thus delivering overall better visual quality.

TAA disabled:

TAA enabled:

To enable/disable TAA, use the render_taa console command (or Rendering panel -> Features -> TAA in UnigineEditor). When TAA is disabled, the fast approximate anti-aliasing (FXAA) can be used. However, TAA implementation is very performance-optimized, so it is recommended to always keep it on.

Environment Probes

Added high-quality environment probes (LightEnvironmentProbe) for creating dynamic reflections instead of creating reflection materials. They highly increase performance because they require less materials (i.e. reducing DIPs). Environment probes can use pre-baked static cubemaps or dynamically grab the surrounding environment (thus creating dynamic reflections). This cubemap influences reflections and lighting of all objects that have entered into the environment probe's radius.

Unlike other engines, UNIGINE 2 has unique environment probes: they can also work with transparent objects, rendered in the deferred pass.

To add the environment probe to the scene via UnigineEditor, do the following:

On the Menu bar, click Create -> Light -> Environment Probe. Place the object somewhere in the world. Grab a new cubemap texture for the environment probe (Light -> Grab texture button in the Nodes window) or load the pre-baked one. Adjust the environment probe settings.

Effects

Improved SSAO (Screen-Space Ambient Occlusion) quality: now it works sub-pixel and supports far objects.

Improved the bloom effect quality: now it works per-pixel, its radius changes dynamically depending on the pixel brightness, and it can be modulated by the dirt texture. The old glow effect has been removed (it can be simulated with the new bloom).

Improved motion blur quality: now it works per-object and supports objects without physical bodies assigned.

All HDR effects can now be adjusted independently.

Added the sharpen post-effect.

world_log_async and filesystem_log_async console commands have been replaced with async_log_mode and async_log_priority.

Procedural content of ObjectGrass and ObjectMeshClutter is now generated in a separate thread.

As a result, the majority of annoying micro-freezes were eliminated, greatly increasing FPS stability and improving synchronization between IG channels in multi-channel setups.

Performance Profiling

Integration with Microprofile

Added support for microprofile, an external embeddable CPU/GPU profiler with support for per-frame inspection. The profiler serves output as a local web server (works in the Google Chrome web-browser only), the default TCP port is 1337.

To build the engine with support for microprofile, use the USE_MICROPROFILE preprocessor macro. It is enabled by default for Mac and Linux operating systems, Visual Studio 2012+ is required for building on Windows (because of some C++11 features).

Default Profiler

Fixed profiling for more than one frame.

Added profiling covering for all engine segments.

Added integration with microprofile: you can use engine.profiler functions to profile a certain piece of your code via counters.

Added the extended FPS counter mode (enabled via the show_fps 2 console command): display of minimal/average/maximal FPS values over the last 600 frames.

Support for DIS, HLA and C2 Protocols

Introducing integration of the Calytrix LVC Game library, which enables communication between components of distributed simulation systems via the standard protocols: DIS, HLA and C2 (mostly used for military projects). Thanks to that now it is possible to connect UNIGINE 2 seamlessly into your training environment.

Integration works by means of the LVC Game add-on, available only in the UNIGINE 2 Sim edition.

Motion Capture

Introducing integration of the following popular motion tracking systems:

ARTTRACK is a tracking software controlling functions of the tracking system. An ARTTracker add-on is used for integration with this technology.

Support for super high resolution (offscreen rendering) - you can take 4K/8K images even on a regular 1080p monitor.

Capturing sequences of frames according to the TRACK file.

Background alpha masking.

Support for increased color precision (16-bit per channel).

Scene warmup before capturing.

Support for professional EXR format, in addition to TGA, JPG, PNG, PSD.

The tool is available only for the Professional and Sim editions.

SDK Browser

License Management

SDK Browser is now managing licenses for the current machine: in order to use UnigineEditor or debug builds of the engine, it is required to keep the SDK Browser launched. Release builds of the engine does not require connection to the SDK Browser.

If you do not have a stable internet connection, SDK Browser can work in offline mode. In this case you will need to perform offline license activation (required only once per machine): go to Options -> Manage licenses and follow on-screen instructions.

Projects Upgrade

Now it is easy to upgrade your project content to the newest version right in the SDK Browser by pressing the Upgrade available button. A backup copy of your project will be created before the upgrade process and, a migration report will be opened in your browser at the end of the process.

Automatic upgrade is available for:
