1.9 - Opacity Mask Clip Value

An overview of the Material Instances example level, example 1.9: Opacity Mask Clip Value



We learned earlier that the Masked BlendMode only has pixels that are completely opaque or completely transparent. You can use a grayscale texture or a single channel from a texture to use as a mask. Clip Value lets you set a threshold when the pixel will be opaque or transparent. For textures that have thin sections, those areas will disappear in the distance as the mipmap forces the white out of the image or channel, adjusting Clip Value will allow you to adjust when that occurs.

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.
