Worked on the DaemonEngine/Daemon repository to enhance the stability of its rendering engine, focusing on defensive coding practices in C++ for game development. Addressed a critical bug by implementing safeguards against uninitialized tag data in iqm and md5 tag handling, which previously led to crashes when tags were missing. The solution involved initializing the tag’s axis and origin before any dependent operations, ensuring safer data paths and reducing the risk of NaN propagation. This targeted fix improved the reliability of tag processing and provided clearer commit traceability, supporting easier future maintenance and contributing to the overall robustness of the engine.
