nathan mitchell	d817f21d71	Modeling Tools: Provide support for the IMeshDescriptionProvider to provide "empty" MeshDescriptions, for cases where such instances are desired such as changing topology. This change creates extendable infrastructure parallel to the existing MeshDescription provider implementations so clients of the empty MeshDescription instances do not need localized specialization based on ToolTarget subclasses. ... This change addresses the errors found with applying certain modeling tools to skeletal meshes due to the old code not using the appropriately setup MeshDescription for skeletal meshes. #rb Ryan.Schmidt #rnx #jira UE-138420 #preflight 61d8dbc4430de36baa5fd904 #ROBOMERGE-AUTHOR: nathan.mitchell #ROBOMERGE-SOURCE: CL 18588220 in //UE5/Release-5.0/... via CL 18588227 via CL 18588243 #ROBOMERGE-BOT: STARSHIP (Release-Engine-Test -> Main) (v899-18417669) [CL 18588249 by nathan mitchell in ue5-main branch]	2022-01-12 14:53:07 -05:00
ryan schmidt	27ba71e214	ModelingTools: Add support for reading and writing to a specific LOD via IMeshDescriptionProvider/Committer. Refactor various other aspects of MeshDescription access. Update MeshTransferTool to be able to transfer from and to specific LODs. ... Add new MeshTargetInterfaceTypes.h file, move EStaticMeshEditingLOD there and rename to EMeshLODIdentifier. Add FGetMeshParameters and FCommitMeshParameters types. IMeshDescriptionProvider::GetMeshDescription() now takes FGetMeshParameters to optionally specify LOD. Added IMeshDescriptionProvider::GetMeshDescriptionCopy() function, to handle copy-case. removed IMeshDescriptionProvider::CalculateAutoGeneratedAttributes(). This was only being used to force Tangents computation, which can now be done via GetMeshDescriptionCopy() and FGetMeshParameters.bWantMeshTangents option IMeshDescriptionCommitter commit functions now take a FCommitMeshParameters to optionally specify target LOD. StaticMeshComponentToolTarget::GetMeshDescriptionCopy() added, optionally computes auto-generated MeshDescription attributes on the copy StaticMesh(Component)ToolTarget updated to support FCommitMeshParameters target-LOD. SkeletalMesh, Volume, and DynamicMesh ToolTargets updated for new APIs but do not currently support any of the new LOD parameters. These should never be called w/ LOD parameters in the current codebase, ensures added to catch any errors (they would be non-fatal). UE::ToolTarget::GetMeshDescription() and GetMeshDescriptionCopy() in now take FGetMeshParameters argument. Removed bWantMeshTangents param to GetMeshDescriptionCopy(), now done via FGetMeshParameters. Updated call sites. TransferMeshesTool now supports specifying read and write LOD (numbered or HiRes) for StaticMeshComponent source/target, via above functions. TransferMeshesTool can now also target a new LOD in a StaticMeshComponent, index is 1 larger than current maximum source LOD. #rb lonnie.li, rinat.abdrashitov #rnx #jira none #preflight 61b8d56b2e65a1df046aa5e1 #ROBOMERGE-AUTHOR: ryan.schmidt #ROBOMERGE-SOURCE: CL 18461686 in //UE5/Release-5.0/... via CL 18461725 #ROBOMERGE-BOT: STARSHIP (Release-Engine-Staging -> Release-Engine-Test) (v899-18417669) [CL 18461778 by ryan schmidt in ue5-release-engine-test branch]	2021-12-14 18:40:01 -05:00
