6.1 - Shadow Bias

An overview of the Lighting example level, example 6.1: Self Shadowing Accuracy


6.1 - Shadow Bias

This example shows off the Shadow Bias. This property exists primarily to help objects feel more grounded along a surface. There is a tradeoff, however, in that decreasing the value to make an object appear more grounded can sometimes lead to self-shadowing artifacts, as seen in the image below:


The diagonal streaks on the surface are the result of these artifacts, created from a low Shadow Bias value. It should be noted that you will generally not need to change this property, as the default will work in most instances.

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.
