How to Import Materials Into 3DS Max
Autodesk 3DS Max creates and renders three-dimensional computer models. These models can have lifelike materials and textures to provide added realism. The default materials in 3DS Max are excellent, however they are very limited. To create more variety in the rendered model, it is useful to import other materials you have made or downloaded from the Web.
Open Autodesk 3DS Max and a model file. Click on the "Material Editor" button. Click the "Get Material" button, and the "Material/Map Browser" window will open. Select "Mtl Library" in the "Browse From:" category and click the "Open" button under the "File" category.
Browse to and select your material and click "Open." Click and drag the material from the "Material/Map Browser" window to one of the material slots in the "Material Editor" window. The material slot will change, reflecting the imported material.
Add maps to the material for increased realism by selecting the collapsible window "Maps" in the "Material Editor." Determine the characteristics of the material, such as roughness, reflectance, glossiness and bumpiness, and add image maps to the various map channels, such as "Diffuse," "Reflect," "Bump" and "Displace." The maps add three-dimensionality to a material without affecting the computer resource use or rendering requirements of the model.
Adjust each map's orientation, scale and tiling in the collapsible "Coordinate" and "Bitmap Parameters" windows after clicking each map's image selection button. When you are finished, click "OK" and drag the material from the "Material Browser" to the 3DS Max object you would like to change to your imported material.
