shadows look pixelated

shadows look pixelated

Hello,

I'm having an issue with the lighting information looking blotchy and noisy in the app. It almost looks like compression artifacts. On the engine, lighting looks clean and smooth so I'm not sure what i'm doing wrong.

here's a comparison of how it looks in the engine vs the app

Any help would be appreciated, thanks!
