Height fields

Height Field Manager GUI

You add new fields with the height field manager GUI. 

This GUI shows all the height fields living in your scene.

If you right click on an height field item, a menu will pop up. From there you will be able to "Edit", "Reload", "Delete" and "Select" it.

Height fields in Maya support multiple meshes, in Houdini you will have to combine your mesh before passing it as source mesh for your height field.

Animated height fields are available in Atoms. Atoms rebuilds the animated height field internal data at each frame, for this reason they are less performing than static height fields.

When creating an height field you can choose the default KdTree structure or BVH. 

BVH is a ray cast acceleration structure to store an height field. It's a lot faster to build compared to the default KdTree, but is can be slower to raycast. We suggest to use it with animated height field or with big meshes.
