I don't think there's a specific "allowable amount" of AI usage. The real issue is how it's being used.
Using AI as a tool to help solve problems, explain concepts, generate boilerplate code, or assist with things you don't yet know—such as shader programming, optimization techniques, or a particular API—is no different from using documentation, Stack Overflow, or asking another developer for advice. You're still making the decisions, understanding the implementation, and integrating it into your project.
Thank you for reading.
