Reuse proxy models with surface mapper

In this blog we'll showcase how the surface mapper enables reusing the same model as LOD levels for multiple models with different topology. It also showcase how you can bake materials to an self supplied proxy model.

Best practices

Billboard cloud mode: Outer shell

The billboard cloud aims to replace the objects in a scene with a view independent set of billboards. The Billboard mode: Outer shell makes the planes fit to the outer shell of objects, as opposed to Billboard mode: Foliage.

Best practices

Impostor: Billboard cloud for vegetation

The billboard cloud aims to replace the objects in a scene with a view independent set of billboards. For vegetation assets the "Billboard mode" should be set to "Foliage" . This mode allows the billboards to represent the foliage volume with intersecting planes. The leaves should map to the billboards in a manner that keeps the perception of volume and silhouette close to the original tree.
