Fixed cloth simulation generating incorrect normals.
Also added option in Cloth Component to update normals of static particles (disabled by default).
User will want to keep the option disabled when continuity of the normals is important, like in characters, but for environmental cloth the mesh could look better when the normals of static particles are updated too.
Enable 'Update normals of static particles' option on blind slices of Nvcloth gem
Fix unit tests
- Added operator+(Matrix3x4), operator*(float), RetrieveScaleSq and GetReciprocalScaled to Matrix3x4. Used by Cloth CPU Linear Skinning. These operation will be performant as they use SIMD.
- Modified so there are no virtual functions calls at vertex level.
- Caching indices to simplify the loop when applying skinning.
- Caching static variables Matrix3x4 zero and DualQuaternion zero to avoid creating it for every vertex.
- Removing branching to skip joints when the weight is zero, these cases are rarely and this improves performance by removing branching from loops at vertex level.
- Changing skinning influences so it's a continuous block of memory.
- Caching the vector size() if a variable instead of directly using it in a for loop.
- Fixing cloth working with Actors by reading directly from ModelAsset instead from EMFX Mesh.
- Actor caches map from joint indices in skin metadata to skeleton indices so they can be query later.
- Actor cloth skinning reads indices and weights from Model Asset instead from EMFX Mesh.
- Actor cloth skinning with unlimited skinning bones.
- Sort out cloth unit tests by disabling them until there is a way to create an Atom mesh
- Addressing feedback.
