I need a problem that I can’t solve when making the scene, please see the attachment. With the same model, I merged the actors and then built the lights. It was found that there were significant differences between the two models. It’s not good to change the material.,Lack of real lighting feeling.,AO,Shadows are not normal.,Although the light display shadow is checked later.。 Do you know how to fix it? Thank you all and hope to get your answers。
