Questions about the C4 Engine

Do you have a question about the C4 Engine? We don't have any sleazy salesman that will tell you exactly what you want to hear and push you to buy a license. Instead, you can talk to the engineer who actually built the thing, Eric Lengyel. His email address is lengyel@terathon.com.
