Distortion Fading?


#1

This might be a stupid question, but how do I get distortion to fade on certain areas of a texture in unreal?

The problem I’m having is I can’t seem to figure out how to make something refract “less” because the material is already at 0 opacity. I couldn’t find any resources online other than to use meshes (which would look awful).

This is the normal map for reference. I tried blacking out the “blank” part but that didn’t seem to do anything except mess the material up even more.

you need to flatten your normal map… @eclipse97

If you are using the standard refraction mode, “Refraction” is actually the IOR. So use a value of 1.0 to effectively have no refraction/distortion.

You can change your distortion method in the material properties using “Refraction Mode”, and you might want to use pixel normal offset instead.
