What are some common challenges Unity developers face when working on large-scale projects?

Unity Developers working on large-scale projects often encounter challenges such as optimizing game performance, managing complex codebases, and ensuring smooth collaboration between team members. Performance bottlenecks can arise from handling large assets or complex scenes, requiring careful profiling and optimization. Additionally, maintaining clean and modular code is crucial as multiple developers contribute to the same project, making version control and clear documentation essential. Regular communication with designers, artists, and other developers helps to align project goals and resolve issues quickly.
