float ShadowSlopeBias

Remarks

Controls how accurate self shadowing of whole scene shadows from this light are. This works in addition to shadow bias, by increasing the amount of bias depending on the slope of a surface. At 0, shadows will start at the their caster surface, but there will be many self shadowing artifacts. larger values, shadows will start further from their caster, and there won't be self shadowing artifacts but object might appear to fly. around 0.5 seems to be a good tradeoff. This also affects the soft transition of shadows

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
