Node: Hit Test Volume

Hit Test Volumes are used for managing selection in StarCraft II. There are two types of Hit Test Volumes, HitTestTight, mostly for drag selection, and HitTestFuzzy, mostly for click selection.

HitTestTight

HitTestTight nodes define the center mass of a model, and are used extensively for in-game drag selection. These are not a special node type created by the SC2ArtTools. Rather, they are standard 3ds Max primitives that the exporter handles specially based on their names.

HitTestFuzzy

HitTestFuzzy nodes are used as an early pass for click selection. There should be one or more per model, and the whole model should be completely enclosed by HitTestFuzzy geometry. Larger models should use more HitTestFuzzys to better match the model's actual form. However, only one will suffice for small models. HitTestFuzzy nodes are not a special node type created by the SC2ArtTools. Rather, they are standard 3ds Max primitives that the exporter handles specially based on their names.

Common Properties

HitTestTight and HitTestFuzzy share many common constraints and properties.
