Thanks to built in terrain , time of day, ocean and volumetric fog systems. There is also a gfx pack with various environmental meshes , cloud , particles, materials and skyboxes.
Pro Cloud gems
Online oriented plugins composed by both client, server and administration components to easily add various online capabilities without further work (es leaderboards, login, message of the day, downloadable contents).
Since version 1.7 they has been released at a steady rate.
Pro Uses AWS cloud
Other than common aws functionality it supports game specific Game Lift for autoscaling game servers.
Pro New Fbx Importer adds support for every software exporting in fbx
It now works for both static models and animations and support advanced setups(es lods and physics).
Pro Roads and Rivers Tool
Built in support for roads and rivers to ease the design of rich game environments.
Pro Rendering of volumetric fx with full light and shadows support
Global environmental volumetric fog and/or hand placed custom shaped volumes with featuring full lighting and shadows.
Pro Very Flexible Base Shader with many built in techniques
Tessellation and Displacement.
Various Parallax Mapping techniques(POM siluette).
Translucency and Sub surface scattering.
Advanced uv transformation and animation.
Pro Flexible uber shaders with cache and hot reloading
You can modify shaders while testing the game.
Shader files are modular and annotated to setup the material editing gui and filter out mutually exclusive options. All shader permutation are compiled almost instantly from the asset processor and cached for later use.
Pro Advanced VR support and VR Samples to bootstrap your project
Advenced stereoscopic reprojection to save rendering time.
Pro Total Illumination v2 Realtime GIobal Illumination
Realistic looking lighting bounces.
It doesn't require long offline precomputation times like other static and dynamic GI solutions based on lightmaps or other similar techniques.
Pro Built-in Twitch support even by visual scripting
You can create games that react to keywords entered in a designated Twitch channel and let streamers to invite targeted viewers into their game sessions on demand with ease.
Pro Very lightweight and scalable entity component system
Multiple entity contexts, reflection, serialization, replication, script binding, event bus (EBus) messaging, fully cascading prefabs (slices).
Every reflected property can be fully exposed in the editor with a customizable gui control and can be animated in the built in animation tools.
Pro Specular reflection antialiasing
Implements the most recent technique available (published in 2017) from Anton Kaplanyan.
Pro Amazon has announced 3 in house games using it developed from Amazon Game Studios
As a proof of how much Amazon is committed to the project.
The first game Breakaway (e-sport and streaming oriented fast paced MOBA) is actually in beta stage.
Pro WWise LTX Audio
It is still possible to use the non LTX version with few changes.
Pro Lua scripting with the built-in IDE
Built-in Lua editor with remote debugger to debug Lua scripts running in any device.
Pro Cutting edge character shaders
Has skin shaders with subsurface scattering and weighted wrinkle maps, eye shaders with refraction parallax, hair with anysotropic specular reflections, etc.
Pro Advanced in-game UI with 2D and 3D placing
The UI uses the entity component system so it's fully modular and easily expandable. The UI is easily skinnable and supports border scaling images (scale 9). Powerful layouting system supporting multiple screen resolutions. Being based on the entity system every property can be fully animated.
It is elegantly managed in a separate entity context so it doesn't get messed up with other kind of entities and their components like in other engines, but it's fully decoupled communicating with entities in other context on specific event buses.
Pro Every aspect of the engine is made with scalability in mind
Multiple grain of control over any kind of engine setting and various kind of Lod systems. Settings can be grouped and applied in batch.
Pro Cinematic multitrack tool with full featured animation editing
Animation Spline editor supporting huge range of keyframing and tangent editing tools.
Pro Virtual file system with live reload on any device
Optimized versions of assets can be streamed live to any device connected over the network.
This makes possible to implement asset types that hot reloads reducing drastically the time to test new content and little changes on device.
Pro Is the first engine to feature SpeedTree 8
Pro Full HDR renderer path with output support for HDR tv standards
Updated renderer pipeline to leverage the full spectrum of precision, luminosity and image processing features of the latest HDR tv.
Pro Implements the state of the art for Temporal Antialiasing from NVIDIA Research
Special iteration of Temporal AA to battle the ghosting issue omnipresent in engines using other Temporal AA techniques.
Pro High quality free assets packs
Amazon made available a selection of triple A quality scenes filled with high quality assets.
Pro Perforce versioning system pre-integrated with the tools
Perforce also comes with a free version for a limited number of team members.
Pro Order independent transparencies
A must for problematic things like hair , vegetation and scenes with complex solid transparent objects(es glass of water with ice cubes).
Pro Slices a very powerful nested prefab system with hierarchical property inheritance
Modular workflow and flexible cascaded propagation of changes.
Pro Built-in weather system
It is possible to edit weather conditions (rain, thunders,wind, clouds, night and day cycle) by simply moving some sliders.
Pro UI is intuitively laid out
Important functions can easily be seen and accessed, making the engine quite user friendly, even for beginners or those who are new to the engine.
Pro Great rendering
S2ENGINE HD rendering power is comparable to more famous engines like Cryengine and UE4.
Pro Complete terrain editor
S2ENGINE HD is integrated with a complete terrain editor that lets you sculpt, paint, add vegetation, and add splines like roads, rivers, fences, etc.
Pro Easy to use
Essential functions are very easy to use and understand.
Con Some Legacy systems are still incompatible or not fit well with the new entity component system.
At first it is common to try a feature and then understand that it is meant to work with the legacy system and not with the newest one.
Legacy systems get replaced or updated to work well with the new entity component system in every new version, but there is still some work to do.
One example for all Flow Graph visual scripting is meant for the legacy entity and Script Canvas is the visual scripting conterpart for the new entity system, but it is still not available at the moment.
Con No source code repository with updated development branch (requests for Github support currently pending)
You need to wait up to 30 or 60 days for fixes as they are shipped with the next official release.
There is no comfortable way to submit fixes and changes to the engine as the forum is the only tool for sharing code.
Con CryEngine with AWS plugins
Con Still in early access
Might be quite buggy.
