Example of adding an Organic Collider to a simple Capsule.

Where to find

The Organic Collider can be found under Mechanics > Collider Generators > Organic Collider (VHACD)

Feature Overview

Create Organic Collider

Create Organic Collider
Filter out Duplex Vertices	Filter out double vertices
Concavity	Maximum allowed concavity (default=0.0025, range=0.0-1.0)
Alpha	Controls the bias towards clipping along symmetry planes (default=0.05, range=0.0-1.0)
Beta	Controls the bias towards clipping along revolution axes (default=0.05, range=0.0-1.0)
Min Vol. per Convex Hull	Controls the adaptive sampling of the generated convex-hulls (default=0.0001, range=0.0-0.01)
Resolution	Maximum number of voxels generated during the voxelization stage (default=100,000, range=10,000-16,000,000)
Max Vertices per Convex Hull	Controls the maximum number of triangles per convex-hull (default=64, range=4-1024)
Plane Downsampling	Controls the granularity of the search for the "best" clipping plane (default=4, range=1-16)
Convex Hull Downsampling	Controls the precision of the convex-hull generation process during the clipping plane selection stage (default=4, range=1-16)
Pca	Enable/disable normalizing the mesh before applying the convex decomposition (default=0, range={0,1})
Convex Decomposition Mode	0: voxel-based approximate convex decomposition. 1: tetrahedron-based approximate convex decomposition (default=0, range={0,1})
Convex Hull Approximation	Enable/disable approximation when computing convex-hulls
OpenCL acceleration	Enable/disable OpenCL acceleration (default=0, range={0,1})
Max Convex Hulls	Maximum number of convex hulls to produce
ProjectHullVertices	This will project the output convex hull vertices onto the original source mesh to increase the floating point accuracy of the results
Generate Collider For Selection	Generates a collider for the selected object
