Edit Material for multiple objects

I need to edit to remove the environmental textures in many materials. The question is, if there is a way to remove all environment textures in all materials? Is there a way using a script or do I have to remove all environment textures one by one?

Background: I want to export a file to Prospect VR, a plugin that translates the file for VR Goggles. That’s no problem, but I use on many materials environment textures. Any materials with environment textures prevent a successful export …

Thank you for your help

Hi Mirko - you should be able to select all the objects with the materials to change and edit that material property in Properties > Material for all at once.
