problem when exporting to modeler to painter

Hi @Arima_Alves2913,

Thank you for the message.

This is because of the model's topology. A bad topology can quickly create visible artifacts depending on the 3D Engine. Therefore, there are now 2 solutions. Either you retopologize the Low Poly to get a clean mesh, or you use a dense enough High Poly and bake it, so it will correct those normals.

Best regards,
