Bounds Source code

ClothIndexBuffer Source code

Index buffer for simulation cloth.

ClothMesh Source code

Cache of ClothMesh objects at different scales.

ClothMeshScale Source code

Scale of each of the ClothMesh objects in cache. This array is same size as ClothMesh.

ClothToGraphicsVertMap Source code

Mapping between each vertex in the simulation mesh and the graphics mesh. This is ordered so that 'free' vertices are first, and then after NumFreeClothVerts they are 'fixed' to the skinned mesh.

ClothTornTriMap Source code

Map which maps from a set of 3 triangle indices packet in a 64bit to the location in the index buffer, Used to update indices for torn triangles. Note: This structure is lazy initialized when a torn cloth mesh is created. (But could be precomputed in BuildClothMapping() if serialization is handled correctly).

ClothWeldedIndices Source code

This will hold the indices to the reduced number of cloth vertices used for cooking the NxClothMesh.

ClothWeldingDomain Source code

This is the highest value stored in ClothWeldingMap

ClothWeldingMap Source code

Mapping from index of rendered mesh to index of simulated mesh. This mapping applies before ClothToGraphicsVertMap which can then operate normally The reason for this mapping is to weld several vertices with the same position but different texture coordinates into one simulated vertex which makes it possible to run closed meshes for cloth.

LODModels Source code

NameIndexMap Source code

NumFreeClothVerts Source code

Point in the simulation cloth vertex array where the free verts finish and we start having 'fixed' verts.

PerPolyBoneKDOPs Source code

KDOP tree's used for storing rigid triangle information for a subset of bones. Length of this array matches PerPolyCollisionBones

RefBasesInvMatrix Source code

RefSkeleton Source code

ReleaseResourcesFence Source code

SkeletalDepth Source code

SkelMeshGUID Source code

GUID for this SkeletalMeshm, used when linking meshes to AnimSets.

Sockets Source code

Cloth

bClothMetal Source code

Whether cloth simulation should be wrapped inside a Rigid Body and only be used upon impact

bEnableClothBendConstraints Source code

Enable constraints that attempt to minimize curvature or folding of the cloth.

bEnableClothDamping Source code

Enable damping forces on the cloth.

bEnableClothLineChecks Source code

Enable cloth line/extent/point checks. Note: line checks are performed with a raycast against the cloth, but point and swept extent checks are performed against the cloth AABB

bEnableClothOrthoBendConstraints Source code

Enable orthogonal bending resistance to minimize curvature or folding of the cloth. This technique uses angular springs instead of distance springs as used in 'bEnableClothBendConstraints'. This mode is slower but independent of stretching resistance.

bEnableClothPressure Source code

Enables pressure support. Simulates inflated objects like balloons.

bEnableClothSelfCollision Source code

Enables cloth self collision.

bEnableClothTearing Source code

Used to enable cloth tearing. Note, extra vertices/indices must be reserved using ClothTearReserve Also cloth tearing is not available when welding is enabled.

bEnableClothTwoWayCollision Source code

Enables two way collision with rigid-bodies.

bForceNoWelding Source code

Forces the Welding Code to be turned off even if the mesh has doubled vertices

bUseClothCOMDamping Source code

Enable center of mass damping of cloth internal velocities.

ClothAttachmentResponseCoefficient Source code

How much an attachment to a rigid body influences the cloth

ClothAttachmentTearFactor Source code

How much extension an attachment can undergo before it tears/breaks

ClothBendStiffness Source code

Controls strength of springs that stop the cloth from bending. bEnableClothBendConstraints must be true to take affect.

ClothBones Source code

Vertices with any weight to these bones are considered 'cloth'.

ClothCollisionResponseCoefficient Source code

Response coefficient for cloth/rb collision

ClothDamping Source code

Controls how much damping force is applied to cloth particles. bEnableClothDamping must be true to take affect.

ClothDensity Source code

This is multiplied by the size of triangles sharing a point to calculate the points mass. This cannot be modified after the cloth has been created.

ClothFriction Source code

Controls movement of cloth when in contact with other bodies.

ClothIterations Source code

Increasing the number of solver iterations improves how accurately the cloth is simulated, but will also slow down simulation.

ClothMetalImpulseThreshold Source code

Threshold for when deformation is allowed

ClothMetalMaxDeformationDistance Source code

Maximum deviation of cloth particles from initial position

ClothMetalPenetrationDepth Source code

Amount by which colliding objects are brought closer to the cloth

ClothPressure Source code

Adjusts the internal "air" pressure of the cloth. Only has affect when bEnableClothPressure.

ClothRelativeGridSpacing Source code

Controls the size of the grid cells a cloth is divided into when performing broadphase collision. The cell size is relative to the AABB of the cloth.

ClothSleepLinearVelocity Source code

Maximum linear velocity at which cloth can go to sleep. If negative, the global default will be used.

ClothSpecialBones Source code

Vertices with any weight to these bones are considered cloth with special behavoir, currently they are attached to the physics asset with fixed or breakable attachments.

ClothStretchStiffness Source code

Controls strength of springs that attempts to keep particles in the cloth together.

ClothTearFactor Source code

Stretch factor beyond which a cloth edge/vertex will tear. Should be greater than 1.

ClothTearReserve Source code

Number of vertices/indices to set aside to accomodate new triangles created as a result of tearing

ClothThickness Source code

How thick the cloth is considered when doing collision detection.

SkeletalMesh

AddToParentPerPolyCollisionBone Source code

For each of these bones, find the parent that is in PerPolyCollisionBones and add its polys to that bone.

bForceCPUSkinning Source code

All meshes default to GPU skinning. Set to True to enable CPU skinning

BoundsPreviewAsset Source code

Asset used for previewing bounds in AnimSetViewer. Makes setting up LOD distance factors more reliable.

bPerPolyUseSoftWeighting Source code

If true, include triangles that are soft weighted to bones.

bUseFullPrecisionUVs Source code

If true, use 32 bit UVs. If false, use 16 bit UVs to save memory

bUseSimpleBoxCollision Source code

If true, use PhysicsAsset for extent (swept box) collision checks. If false, use per-poly bone collision (if present).

bUseSimpleLineCollision Source code

If true, use PhysicsAsset for line collision checks. If false, use per-poly bone collision (if present).

FaceFXAsset Source code

The FaceFX asset the skeletal mesh uses for FaceFX operations.

LODBiasPC Source code

LOD bias to use for PC.

LODBiasPS3 Source code

LOD bias to use for PS3.

LODBiasXbox360 Source code

LOD bias to use for Xbox 360.

SkeletalMeshLODInfo Source code

Struct containing information for a particular LOD level, such as materials and info for when to use it.
