The following is a list of important facts about the C4 Engine license.
Frequently Asked Questions
Below are answers to many of the general questions we receive. Additional questions of a more technical nature are answered in the wiki FAQ article.
How can I evaluate the C4 Engine? Can I get the source code so I can make a test game?
The standard evaluation package is included with the demo available on our download page. It includes all of the editing tools that ship with the C4 Engine. For obvious reasons, we cannot provide an SDK for evaluation that contains the necessary source code for creating a test game.
What versions of Windows are supported?
The C4 Engine runs under Windows XP, Windows Vista, Windows 7, and Windows 8.
Does the C4 Engine work on the Mac?
Yes, the C4 Engine runs on the Mac, and Mac support is included at no additional cost. Mac OS X 10.9 or later is required.
How do I get the C4 Engine for the PS4?
First, become a licensed developer with Sony. This will require that you have formed a legal corporation of some kind. Once this is all handled, contact us for information about studio-wide PS4 licensing.
What are the minimum graphics hardware requirements of the C4 Engine?
The C4 Engine runs on graphics processors from Nvidia and AMD that meet certain functionality requirements. For Nvidia hardware, a GeForce 8x00 or higher is required. For AMD hardware, a Radeon HD 2600 or higher is required. Note that these graphics cards are quite old, and newer cards will provide a much better experience.
Does the C4 Engine run on Intel GPUs?
Yes, the C4 Engine runs on Ivy Bridge and later GPUs from Intel. It's important that the latest drivers be installed first.
How many polygons can the C4 Engine render per frame?
There are no internal limits to the size of a scene, but the number of polygons rendered is rarely a limiting factor when it comes to an engine’s performance. Many factors influence the rendering speed, and these include the complexity of the materials used, the number of shadows drawn and their types, whether various kinds of special effects are enabled, and how heavy the load on the physics simulation is. There aren’t any specific numerical limits for any of these that can be stated. As with any engine, speed will generally be determined by how well levels are designed.
What do I need to build the C4 Engine source on Windows?
The C4 Engine ships with project files for Visual Studio 2013. The Express Edition of Visual Studio can be obtained for free from Microsoft.
What do I need to build the C4 Engine source on the Mac?
The C4 Engine ships with project files Xcode 4, which can be obtained for free from Apple.
Do I need a studio license?
You only need a studio license if you are developing for consoles or you have received at least $100,000 in funding from an external source (such as a publisher or Kickstarter campaign). Please contact us at email@example.com if you need a studio license.
Does everyone on my team need a license?
Yes, each person on your team needs to be a licensed user of C4 regardless of their job function. Artists, level designers, etc., who don’t need access to the source code still need to have a license (or be assigned to a multi-user license).
For how long do I get updates after licensing the C4 Engine?
The license includes updates for one year, but you can still use the latest version that you have forever.
Is the C4 Engine open source?
No. All licensees are required to keep the C4 Engine source code confidential. You may modify the source code for use in your own products as much as you want, but you may not redistribute your modifications to anyone else.
