CryEngine vs Skyline

CryEngine has some C#template and also C# based system to write your function/ideas in to your game.

CryEngine 5.4 now supports DX12 and Vulkan

Cry Engine has volumetric fog rendering which allows for realistic cloud shadows that actually render shadows onto the fog itself. Combined with their time of day system, it's possible to create incredibly realistic weather effects. On top of this, color grading allows user to post process pallets allowing them to change the color tone for different type weather, such as using a deep dark blue for rain.

It can shoot, walk on patrol points, can see the player and so on.

Cryengine (starting on Cryengine V) has Virtual Reality support. Developers can create games with VR support for multiple platforms: PlayStation VR, Oculus Rift and HTC Vive.

Cry Engine has realistic water effects that even simulate ocean physics. Features such as waves that respond to global wind, and dynamic water volume tessellation allow for some of the most realistic water effects available to a game developer. The engine also takes into account LOD (level of detail) on water geometry to allow it to stay performant for water at a distance.

Where Cry Engine really shines is with rendering scenes of nature. The Crysis games feature incredibly detailed vegetation and weather effects and it's the Cry Engine that enables that. The engine has many features to create a cohesive realistic looking world. Dynamic water effects allow users to have beautiful oceans, fog and cloud effects allow for realistic weather, and a plethora of lighting effects optimized for natural looking scenes make Cry Engine one of the best engines for creating vast beautiful landscapes.

By having all these features built together from the ground up, Cry Engine is capable of doing more complex effects more efficiently, than other engines that didn't have these effects planned from their inception.

Supports miltiple platforms including: Xbox One, Xbox 360, PS3, PS4, Wii U, PC, iOS, and Android.

Flow graphs resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.

Crytek has launched a dedicated Q&A forum for everything Cryengine related. It's called Cryengine Answers and it's a community dedicated to sharing and answering any question related to Cryengine.

The Cryengine marketplace is an online marketplace which enables developers to access and use individual assets from thousands of materials, sounds and 3D objects created by the community. Even Crytek's own library assets are available there.

Cryengine has an optimized volumetric cloud system for Virtual Reality to give clouds full 3D spatial rendering. This ensures a high rendering quality with a minimal performance hit.

Simply by looking at the RC log when exporting can greatly improve your work. Cryengine doesn't handhold you constantly and helps greatly with avoiding bad practices in asset creation.

A growing community that is always helpful with dev response times averaging less then 24 hours. Often less than 12.

Skyline provides a straightforward drag and drop development environment that can be customized to suit individual preferences. Playing the game and animating the scene can be done from within the editor at any time.

Future versions will allow extending editor's functionality with plugins and offer an official way of trading custom plugins.

Skyline's commercial edition costs just £40, has no royalties or earning limitations and includes 2 activations per license purchase and a year of free updates.

Skyline can be run on a machine with 2GHz Dual Core CPU, 2GB of RAM and Nvidia's 9800 GT (or equivalent) GPU. While, obviously, higher specs are recommended, it's reasonable to expect around 60fps on small scenes with these specs.

The Terrain editor is easy to use and will include features such as hole cutting.
There is a differed lighting render for internal scenes, which makes creating multi light and beautiful/atmospheric scenes so much easier.

All the tools for the terrain are in one place such as placing road/paths, vegetation, billboards, and the settings are easy to locate and change.

Planned features include:
Hole cutting in terrain and
Terrain paging.

Making a game in the current top engines is hard work, making something small and basic in Skyline is not. Easy to learn drag an drop model placement and editing supplemented with easy to follow video's on forum make the process straightforward.

Including image based lighting.

A free version that's limited to non-commercial usage and lacks a few features is available.

Rendering of a water plane looks fantastic and is easily edited for different effects.

The schematic editor is designed to make it easier for non-programmers to create games.

Not much in it at the moment but is starting to grow and will continue to grow with an increase of users.

There are many additions to the engine that are on the road map such as multi threading and tree physics.
The feature list is constantly evolving with each user request and idea put forth.

Skyline has a custom editor that gives the user of making their own tools for use directly in the editor to develop their games. All the editors are made using the Qt Designer and programmed in lua inside the engine itself.

Open-Source Virtual Reality support is in development.

The documentation is been rewritten and follows a structure like a course.
Introduction to > Level designer with examples > Artists

There is also video tutorials, video examples and video tutorial series been produced.

There are user created demo scenes, examples and more.

Making HUDs and GUIs has never been easier
