Component:VHACD Dialog

Component image 

VHACD Dialog component as seen in the Scene Inspector

The VHACD_Dialog component or V-HACD 2.0 dialog, is used to do a convex hull decomposition on a mesh to make the collision simpler and more performant.

The V-HACD Dialog window that provides all settings and allows running the decomposition into convex hulls

Fields

Fields

Name	Type	Description
persistent	Bool	Determines whether or not this item will be saved to the server.
UpdateOrder	Int	Controls the order in which this component is updated.
Enabled	Bool	Controls whether or not this component is enabled. Some components stop their functionality when this field is disabled, but some don't.
TargetCollider	MeshCollider	The collider to simplify.
MergeDoubles	Checkbox	Whether to merge double vertices.
Resolution	IntTextEditorParser	maximum number of voxels generated during the voxelization stage
Depth	IntTextEditorParser	maximum number of clipping stages. During each split stage, all the model parts (with a concavity higher than the user defined threshold) are clipped according the "best" clipping plane
Concavity	FloatTextEditorParser	maximum concavity
PlaneDownsampling	IntTextEditorParser	controls the granularity of the search for the "best" clipping plane
ConvexHullDownsampling	IntTextEditorParser	controls the precision of the convex-hull generation process during the clipping plane selection stage
Alpha	FloatTextEditorParser	controls the bias toward clipping along symmetry planes
Beta	FloatTextEditorParser	controls the bias toward clipping along revolution axes
Gamma	FloatTextEditorParser	maximum allowed concavity during the merge stage
Delta	FloatTextEditorParser	Controls the bias toward maximizing local concavity
PCA	Checkbox	enable/disable normalizing the mesh before applying the convex decomposition
Mode	DecompositionMode	how to base the approximate convex decomposition
MaxVerticesPerHull	IntTextEditorParser	controls the maximum number of vertices per convex-hull
MinVolumePerHull	FloatTextEditorParser	controls the adaptive sampling of the generated convex-hulls
ConvexHullApproximation	Checkbox	Approximate the convex hulls.
