Philipp Oeser (lichtwerk) added a project: EEVEE & Viewport.
Philipp Oeser (lichtwerk) added subscribers: Clément Foucault (fclem), Philipp Oeser (lichtwerk).

Here, the result at Factor 1 looks correct, will confirm though since at Factor 0.0, I would assume the result to not be affected by Bent Normals at all?
Or it this a known limitation, @Clément Foucault (fclem)?
