How to get a light to cancel out shadows

Can one light source cancel out the shadows of another on a MeshLambertMaterial?


There is a cube casting a shadow on a plane from a directional light. On the far side of the cube there is a point light that should lighten the shadow but doesn’t. MeshPhongMaterial behaves more like you would expect but is it possible to do this with MeshLambertMaterial?


Maybe this will be helpful:

Yeah, that explains the behaviour. Thank you!
