Input

• One group containing one well-defined perimeter. For instance one closed edge path, or one face, or one surface.
• Multiple groups, each containing a well-defined perimeter.

Parameter

Resolution

Resolution sets terrain mesh cell side length. Resolution is global.

Control values by typing to the VCB whenever Mesh is active.

Operation

Direct

1. Pre-select valid input, per above.
2. Run Mesh.
3. To adjust result, type values.

Mesh is a Pick command.

Mesh can Keep Fence or Erase Fences

Mesh will reset the general terrain mesh topology inside your picked control areas.

However, Fences are special. Fences are terrain edges that have been Fenced.

Per default, Mesh will still keep Fences.

Sometimes, Fences are in the way. You wish to locally get rid of all Fences in your meshed area, and instead start afresh. In Mesh, it is easy to erase Fences locally.

To make Mesh erase Fences, read the VCB label carefully. Follow the instructions.

Currently, in the VCB, the number:

• 1 means Keep Fence.
• 2 means Erase Fence.

Mesh versus Mesh Brush

Mesh is is a Picker.

Mesh lets you interact with the terrain via reusable input geometry, also called control groups. For Mesh, the input area will drive the affected terrain area. Mesh is ideal for accurate work.

However, Mesh also has a corresponding brush tool, called Mesh Brush. Brushes are ideal for more expressive, freeform work. You don't need to first create input geometry to use brushes. Instead, you can simply brush the terrain directly.

Mesh-Pick and Mesh-Brush tools both do the same thing. They change terrain resolution in an area. But they let you control that area in two different ways.

When you need to change terrain resolution within an area with a precise boundary which ought to be reusable — use Mesh.

When you wish to change terrain resolution in a quick, freeform way — use Mesh Brush.

Often, it does not matter exactly where different general terrain resolutions begin.

Workflow Tips

• Landshape terrain is multi-resolution. You may change terrain resolution locally at any time using Mesh or Mesh Brush.
• In general, it is better to start terrain low-resolution, and then increase resolution only where needed. Typically, reserve higher resolution for areas that have special interest, or require granular surface features.
• For a model requiring a large context terrain surrounding a smaller grade site, you could use fairly low resolution for context, and use higher resolution for the site itself.
• For best results, avoid low-resolution terrain areas right adjacent to high-resolution terrain areas. The transition will show awkwardly shaped triangles. If you run into this, set an intermediate resolution, then remesh the transition. A resolution of 2 does not sit well next to 18, but if you add a transitioning band of resolution 6 in between, this will behave better. A great way to achieve this is to use the Mesh Brush.
• Fences are terrain edges that can persist through your remesh operations. Only Fence the edges that you need. Use them to your advantage. Learn more about Fencing.
