Is there a relation between the facetData and the indices of the mesh?

Facet Data Issue

I figured out how to get the vertices that make up a facet: let index = mesh.getClosestFacetAtCoordinates(x, y, z); let facetPosition = BABYLON.Vector3.Zero(); mesh.getFacetPositionToRef(index, facetPosition); let positions = mesh.getVerticesData(BABYLON.VertexBuffer.PositionKind); let indices = mesh.getIndices(); let v1x = indices[index * 3] * 3; let v1y = v1x + 1; let v1z = v1x + 2; let v2x = indices[index * 3 + 1] * 3; let v2y = v2x + 1; let v2z = v2x + 2; let v3x = indices[index * 3 + 2…
