Bug light in Unreal engine 5.1

After the update, lighting does not work well with geometry. Lighting worked fine in unreal 5.03

Upd:This is due to the normal map, an example in the screenshot

Upd2: The fix is ​​to include a nanite for the mesh. That is how it should be?

Is it possible to solve the problem without including nanite ? I have too many assets where I need to enable nanite, this is a bad solution, are there any other ways to remove the problem? and also in 5.1 , when playing particle , frieze is coming .

I had this same problem from porting my project over from 5.0.3 to 5.1. I had to go into the mesh settings and enabled ‘Use MikkTSpace Tangent Space’ and ‘Recompute Tangents’. Then press ‘Apply Changes’. Also check that the tangents and binormals are the same as your old project, by checking ‘Tangents’ and ‘Binormals’ in ‘Show’ in the top left corner.

wow that worked, is there a way to set this parameter for a large number of meshes?
