Stack trace:
Mesh 'NormalCurveRendererMesh': abnormal mesh bounds - most likely it has some invalid vertices (+/-inifinity or NANs) due to errors exporting.
Mesh bounds min=(0.00, 0.00, 0.00), max=(1.60, 4493203713429315721967871983616.00, 0.00). Please make sure the mesh is exported without any errors.
