Unity Shadows are screwing me up

It worked but now it produced some weird curve artifacts, help! @Arnklit

oh nevermind setting bias to 0.2 and normal bias to 0 fixed it thanks

Hmm, yeah that is shadow acne, the reason that shadow bias is there in the first place, but I actually thought it would be ok, with these flat surfaces, you can try and adjust the normal bias as well and see if you can find a place where it looks good. Alternatively you can set that shadows to be double sided on the meshes instead and that should also resolve it.
