What is causing this discreprency between my two scenes?

Hi there,

I’m very new to 3D Graphics and Unity and hoping to get some help. I have downloaded the Polygon - Nature asset bundle from the store and have started a new project + scene to try and replicate what they’ve accomplished.

Here is an image depicting the discrepancy. (The image on the bottom is the correct scene provided in the bundle and the image on top is my scene with the error I’m trying to fix).

The yellow tree is the exact same prefab and the skybox, directional light and project settings are exactly the same (or so I think).

As you can see in the top image, the boulders and trees are harsher and darker with black areas. I realise this isn’t much to go but if if possible could someone point out potential causes for this and how I can go about rectifying it?

Thanks

Ok I have figured it out, I had to go to the Lighting window and uncheck ‘Baked Global Illumination’
