3ds max Map Scaler Modifier

Software:
3ds max 2017

Use the Map Scaler (MapScalar) Object Space Modifier to make UV coordinates conform to a uniform map real-world size.

Tip:
Create effective UV coordinates for angular geometrical meshes quickly by applying an Unwrap UVW modifier, and in the UV Editor, selecting all the mesh, and choosing Mapping > Flatten Mapping, and than applying a Map Scaler modifier and setting its Scale parameter to the wanted texture size..

Notes:

1. When applying the Map Scaler modifier to an object with deformed UV’s, it will break the UV’s in order to force consistent scale.
2. If the Scale parameter matches the file’s system unit definition in Customize > Units Setup > System Units Setup, than it will effectively work as real world map scale, and allow you to set a real world texture size in the Coordinates rollout of the texture in the Material Editor.
