With my extensive knowledge in C# Programming, Game Development, Mobile App Development, and Unity 3D, I believe I am the right fit for your VR project. I understand that you need a competent developer who can efficiently incorporate your .fbx animation and animate it to play forward for 12 hours and then reverse and play backwards. Not only have I done similar tasks in the past but I've also mastered the art of delivering quality work on time.
Moreover, I am familiar with Oculus Quest 2 controllers and can seamlessly integrate them into the scene so that it's fully immersive when played on Quest. Additionally, I'll create a smooth-moving camera outside the VR environment which will help you record the scene effectively from your computer.
Lastly, let me assure you of my unwavering commitment to your satisfaction. Open communication lines are always essential while working on any project. Rest assured, you'll be updated regularly regarding the progress of your project. As a professional, I consider myself accountable for any errors found even after payment is done; thus, ensuring optimum after-sales service. Trust me with your project - expect efficiency, timeliness, and an exceptional final product!
