The sample slots let you maintain and preview materials and maps. Each slot previews a single. You can change the material by using the Compact Material Editor controls, and you can apply the material to objects in the scene. The easiest way to do this is to drag the material from the sample slot to objects in viewports.

• (Material Editor): Compact > Sample slots display

You can display a sample slot in a window of its own. This magnifies the sample slot, which can make it easier to preview the material. You can resize the magnified window to make it even larger. To magnify a sample slot, double-click it, or right-click and choose Magnify from the pop-up menu.

Yeah, managing materials in 3ds Max could be more simple. Fortunately, the 2011 version is a little bit easier to use. In this post I use the 2012 version to illustrate the logic: it’s easier to understand, and in the end I’ll wirte down some advice for 3ds max 2009 and similars. One more clarification before you start.

The Material Editor has 24 sample slots. You can view them all at once, six at a time (the default), or 15 at a time. When you view fewer than 24 slots at once, scroll bars let you move among them.

A material in a slot is shown on a sample object. By default, the object is a sphere. Use the Sample Type flyout to change the sample object.

By default, a standalone map in a slot fills the whole slot. This is when the slot shows only a map; for example, when you drag the map onto the slot from elsewhere in the 3ds Max interface. When a map is assigned to a material, the slot shows it as part of the material, mapped to the sample object.

Hot and Cool Materials

A sample slot is 'hot' when the material in the slot is assigned to one or more surfaces in the scene. When you use the Compact Material Editor to adjust a hot sample slot, the material in the scene changes at the same time.

The corners of a sample slot indicate whether the material is a hot material:

• No triangle: The material is not used in the scene.
• Outlined white triangle: The material is hot. In other words, it's instanced in the scene. Changes you make to the material in the sample slot will change the material displayed in the scene.
• Solid white triangle: The material is not only hot, but is applied to the currently selected object.

Left: 'Hot' material applied to currently selected object.

Middle: 'Hot' material assigned to scene but not to currently selected object.

Right: 'Cool' material: active but not assigned to scene.

A material is 'cool' if it is not applied to any object in the scene.

To make a hot sample slot cool, click (Make Material Copy). This copies the material in the sample slot on top of itself so that it's no longer used in the scene.

You can have the same material (with the same name) in more than one sample slot, but only one slot containing that material can be hot. You can have more than one hot sample slot, as long as each has a different material.

If you drag to copy a material from a hot slot to another slot, the destination slot is cool, and the original slot remains hot.
