Since my animation causes stretching, the bones must be slightly offset downward.</p> <p><img alt="Checking bone positions in Blender" loading="lazy" sizes="(max-width: 767px) calc(100vw - 30px), (max-width: 1023px) 700px, (max-width: 1279px) 950px, 1232px"></p> <h2 id="model-lying-down-after-blender-export">Model Lying Down After Blender Export </h2><p>Check the <strong>Y Up</strong> option in the export settings.</p> <p><img alt="Blender export settings" loading="lazy" sizes="(max-width: 767px) calc(100vw - 30px), (max-width: 1023px) 700px, (max-width: 1279px) 950px, 1232px"></p> <p>If the model is still lying down, try changing Y Up to something else, export, then switch back to Y Up and export again. That fixed it.</p>
