Hi guys,

    So, looking at this solution :

Diagram on the left - the cube (or square as it's shown in the diagram) shows the faces shifted along the normal, introducing gaps.

Gaps cause light leakage through them.

> You don't use the  normal-offset approach at shadow map creation but when sampling the shadowmap.

Doh :)

Thanks, Daniel & unbird.

Best regards,
Steve.
