There’s some glare on this object, which comes from the lighting in the original photograph.
The problem is that glare will stay in the same place, even when the lighting on the object is from a completely different direction. Far better to get rid of it altogether.
To get rid of the glare, you need to address the texture that’s wrapped around the object.
You can do this by looking at the Layers panel. In the Textures section, beneath the name of the 3D layer, you’ll see the original texture listed (it may well be called Layer 1).

The texture is stored within the 3D object, and will open as a new .psb document. This is the internal file system that Photoshop uses for artwork that resides inside another layer.
Use the Clone tool, or you could try the Healing Brush, to paint out the shine – the choice is yours. It depends on the situation, as some tools will work better than others. The aim is to hide the shine altogether.
When you now Save the .psb document, the changes will be saved back into the texture that’s wrapped around the pear (note that saving the .psb is not the same as saving the whole file). The glare has now gone, and the lighting is more realistic.
