ThreeJS point light gives weird texture look

I use ThreeJS, more specificaly React Three Fiber to create a 3D Canvas.

I added a glb model, point light and ambient light and the result was really bad.

enter image description here

Why does the texture look so choppy?

Is it because of the material or?

Thank you

I tried to edit intensity and color of the light. No change.

I added a normal cube, with a MeshStandardMaterial and it was okay.

This model was made in Blender, and shadows were baked a bit.
