Shadow artifacts in character

Hi, I’m getting some weird shadow artifacts on the surface of my character, does someone know the reason? Thanks.

Could it be

split vertices
exported sharp edge (Maya, Blender)
wrong normal direction (rotated)?
different smoothing groups (3ds max)

Thanks for the suggestions but unfortunately none of these worked

Hello,
have you tried to increase the resolution of your lightmap?

Maybe its a matter of the light settings for shadows. Check if you have a high enough shadow cascade value (seems like it could be a large jump). Maybe you have a shadow bias set to a value where it favors short distances?
Shadow slope bias also seems to play a role in self shadowing so maybe that could be your culprit.

Do the model’s shadows look ok in you modelling application?

It was indeed a setting of the main light, I didn’t realize I had moved the slider for Contact Shadow Length, Setting it to 0 seems to have solved the problem.
Thanks for your help guys.
