- add new UModelingObjectsCreationAPI and associated data structures, provides abstract API for creating mesh and texture objects from Tools that is not specifically tied to StaticMesh Actors/Assets - new helper functions in UE::Modeling:: namespace to simplify usage of an implementation of this API registered in a ContextObjectStore - add new UEditorModelingObjectsCreationAPI implementation of above, supports hooks for higher level to provide custom paths - add ModelingModeAssetUtils.h, provides several functions in UE::Modeling:: namespace to be used to implement those hooks (various existing path-determination code is moved here) - ModelingToolsEditorMode now registers an instance of UEditorModelingObjectsCreationAPI in ContextObjectStore and connects up callbacks to these path functions - AssetGenerationUtil functions and ModelingModeAssetAPI deleted - All Tools that previously used IToolsContextAssetAPI updated to use this new system #rb jimmy.andrews #rnx #jira none #preflight 60b7c2ddae46a1000162729b [CL 16538450 by Ryan Schmidt in ue5-main branch]
