- new correspondence-finding strategy in FMeshImageBakingCache. Added a global Thickness parameter, and now preferentially uses the ray-hit found by casting inwards from Point+Thickness*Normal. This handles the cases where a greeble/etc is just layered on top of base mesh. These kind of mesh elements are only intended to show up in the normal map, so they aren't stitched in. - expose Thickness and World-Space options in BakeMeshAttributeMapsTool - initialize image in Normal and ResampleImage Bakers, otherwise initial value is garbage - add TSampledScalarField2::BilinearSampleGradientClamped and fix typo in BilinearSampleClamped() that resulted in incorrect interpolation - add Texture2DUtil, contains functions for reading a TImageBuilder from a UTexture2D. Can read from source data if available. - ColorConstants now returns white for group 0 - add double version of FMeshDescriptionToDynamicMesh::CopyTangents() - add support for computing on subset of vertiecs in FMeshConvexHull - fix up template export in TMeshTangents - make mesh const in TImplicitMorphology, TImplicitSolidify - accessor/etc additions in TDenseGrid2, TImageBuilder, TSampledScalarField2, TIndexedWeightMap - add source UStaticMesh reference in FPhysicsDataCollection, function to initialize from a UStaticMesh - update Tools affected by above changes - add TSampleSetStatisticBuilder::ComputeMultiPass() helper function to compute stats for iterable collections in one line - remove dead code in UVLayoutOp.cpp #rb tyson.brochu #rnx #jira none [CL 14769759 by Ryan Schmidt in ue5-main branch]
