Any solutions to this jagged shadows issue?

conscience73

Rendering an indoor scene with a skylight. HDRI, no other lights.

PBR skin shader. Turning off bump, gloss, detail, translucency doesn't affect the result.

Figure is Sub 2. Sub 3 makes a slight difference but the transition is the same. Sharp, with the shadow being too dark.

Tried rendering the scene in Blender. Same HDRI. Problem doesn't exist there, it seems.

Any solutions?

This is an example, I think, of what si called the terminator effect - the transition from the side that is facing the light to the side that is away from the light. Adjusting the nagles slightly can fix it, as can higher  levels of SubD - I think there may be other options, if you search (here or in general, though the latter will probably produce a   lot of Arnie stuff) for terminator effect (try adding rendering to the search terms)
