any changes of a material runtime is saved in the editor.

 

You need to change an instance of the Material, not the original.

But you're asking this in General Discussion, which is explicitly not a support forum. Scripting would be the place for this.

 

yes how to reset that to default?

 

You can't reset to the previous values unless you kept a separate copy of the material. Otherwise you'll have to change them manually again.

To avoid this happening again do like angrypenguin said, create an instance of the material and reference the instance in script.
