Worked on the godotengine/godot repository to address a critical issue in the scene tree editor, focusing on the paste_node_as_replacement operation. Implemented a fix in C++ that ensures the entire transform—including position, rotation, and scale—is re-applied to new nodes during replacement, supporting both 2D and 3D scenes. This change eliminated transform drift and reduced the need for manual adjustments, streamlining scene construction and improving editor reliability. Demonstrated expertise in editor functionality, scene management, and transform mathematics, with careful alignment to existing editor workflows. The work enhanced the accuracy and stability of node replacement within the Godot editor pipeline.
