Volume Displace Modifier
The Volume Displace modifier.
Texture
The texture that is evaluated at every voxel to determine how far and in what direction to displace.
Grayscale textures lead to stretching along one axis. It’s best to use a color texture.
Strength
Controls how far voxels are displaced.
Sample Radius
Mid Level
This should be modified if the texture offsets the entire volume in one direction and you want to center it again. For performance reasons, the displaced volume should stay close to its original position.
Example
A volume displaced with various strengths.
