Talk:Painting Bump Maps

From ZBrush Info

Hi, I think that the users do not use polypaint function to painting Bump color, this method is defective.

First, Bump color depends on the number of vertices of the current model. Usually, it does not show smooth effect(Bump). Even if we use HD Divide function, the effect is still not smooth. And as the number of vertex model growing ,software operating speed is reduced.when we use HD Divide function, the system will consume enormous resources. The painting operation will not become fluent, and 'Undo' operation will be very slowly.

Therefore, I recommend the users choose 'Pm' function to paint Bump map, it's advantages: The effect is very smooth; very little system resources consumption; 'Undo' and painting operation will be very smooth.

use HD for generating a bump
