How do I swap a shader?
 

I did not know what I did really when I set up a scene with Mia-material-X. Now I want to exchance that shader to a layered-shader instead. Is there an easy way to exchange that shader with another shader on all the objects in a scene without picking each object and face?

I tried deleting the shader and creating a new one with the same name, but that did not work.

Well you can right click the shader in hypershade and choose "select objects with X shader". Easy way to swap.

Thank you!
