What it does

Notes

Source

Object

dropdown

 Select the high polygon object from which you want to calculate the height map.  

Version

dropdown

 Select the high polygon object version from which you want to calculate the height map.  

Size

dropdown

 Set the size of the selected channel on the low polygon object for which you are creating the displacement map.  

Frame

text field, slider

 Set the frame from which you want to calculate the height map.  
Destination

Version

Sampling

Interpolation

dropdown

Interpolation is similar to Photoshop's sampling functionality. You can select the method Mari uses to average out pixels from either:

• Nearest Neighbor- selects the nearest pixel for sampling.

• Inverse Distance Weighted - weights the average on the closest pixels.

• Inverse Distance Weighted (Smoother) - weights the average on the closest pixels with a priority to providing smoother sampling.

• Inverse Distance Weighted (Sharper) - weights the average on the closest pixels with a priority to providing sharper sampling.

  

Sample Count

text field, slider

 Set the number of points the search finds and combines when sampling.  
Center Positions checkbox Choose whether or not to center the sampling position for the height map. This is where the Samples size starts from.  
Bleed Edges checkbox Choose whether or not the height map bleeds over the edges of patches.  
Range Amount text field, slider The range (distance) to which the height map extends. The units in which this is measured are determined in Range Units.  
Range Units dropdown

The unit of measurement for the Range Amount field:

• Infinite - the range amount is set in the context of infinite XYZ space.

• World Units - the range amount is set in worldspace.

• Object Size Percentage - the range amount is determined as a percentage of the total size of the object.
