Texture Coordinates

Material textures on imported or linked objects have the same appearance as

within Revit or AccuRender. Of course, the exception to this rule is when

AccuRender procedural textures are used.

When materials from Revit are viewed in the 3ds Max Material Editor, you'll

notice that some settings are not translated or they are not set as you're used

to seeing in 3ds Max. For example, if the texture map of a flooring material

has a rotation of 45 degrees in the Revit project, the rotation setting does not

translate when the model is linked/imported to 3ds Max. The rotation for the

texture map is set to zero in the 3ds Max Material Editor.

Map Scaling

The scale of material textures is of primary importance. The File Link Manager

or DWG/DXF Importer attempts to read and translate the offset and tiling of

the materials so the texture maps appear in 3ds Max as they do in Revit.

However, map scaling may differ because the Tile Size settings in Revit are

measured in decimal feet or meters even if your Project Units are set to Decimal

Inches or Millimeters. Once the model is linked or imported to 3ds Max, you

can turn on Use Real-World Scale and match the Tile Size settings. The main

thing is to pay attention to the Tile Size settings when you create the material

in Revit.

As a example, let's say you've created a material in Revit that uses a brick

texture map with an X: Tile Size set to 20 and a Y: Tile Size set to 16. If you

open that material in the 3ds Max Material Editor, you will find that the Width

and Height Size settings are automatically set to 20' and 16' respectively. The

texture mapping will always be scaled correctly in the scene. How a material

is displayed in the Material Editor depends on whether Use Real-World Scale

is turned on or off.
