Happy Spring Festival! As the Lunar New Year 2026 approaches, our community has voted for the next investigator to be added to #OperationLovecraft. "I do not particularly like being addressed by my model designation. Please call me Grace, Pioneer Council's director of secretariat."

We managed to develop and implement a must-have feature for an adult game: a high quality real-time physics system of higher fidelity for cloth simulation in #UnrealEngine for #OperationLovecraft. The gap between the fabric and the skin is now greatly reduced without mesh clipping. #UE5
