Put Material to Scene

Material Editor > Put Material to Scene

Material Editor menu > Material menu > Put to Scene

Put Material To Scene updates a material in the scene after you edit the material. Put Material To Scene is available only when:

The material in the active sample slot has the same name as a material in a scene.
The material in the active sample slot is not hot.

In other words, this command is intended to fit into the overall sequence of handling materials:

You create a hot material either by applying it to objects in the scene or by getting it from the scene.
You make a copy of the material.
You make changes to the copy of the material.
You update the scene by putting the changed material back into the scene.

Notes

If you apply a mapped material to a parametric object whose Generate Mapping Coords option is off, the software automatically turns on mapping coordinates at render time. In addition, if you apply a mapped material with Show Map in Viewport active to an object, that object's Generate Mapping Coords option is turned on if necessary.
The Show Map In Viewport flag is now saved with individual materials, so you can drag mapped materials from the modeless Browser onto objects in your scene, and the mapping appears in the viewports.

To put a material back into a scene:

On the Material Editor toolbar, click Put Material To Scene.

The material in the active sample slot is now a hot material.
