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.

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.

If you are using shadowmaps, try increasing your shadow bias. https://threejs.org/docs/#api/en/lights/shadows/LightShadow.bias

also it could potentially be an accuracy problem caused by too large or small of a model and your camera clip planes being too large giving it too little accuracy to discern front/back faces of the model. https://threejs.org/docs/#api/en/cameras/PerspectiveCamera.far and also the near property.
