Blast 1.1.2

Blast(tm) SDK 1.1.2 (26-Jan-2018)
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Changes

• Improvements to uniteChunks for hierarchy optimization.
• NvBlastExtAuthoringFindAssetConnectingBonds optimized.
• APEX dependency has been removed (ExtImport used it). Now ExtImport has a built-in NvParameterized read that can load an APEX Destructible asset.

New Features

• FractureTool::setChunkMesh method.
• Distance threshold added to NvBlastExtAuthoringFindAssetConnectingBonds.
• NvBlastExtExporter: IMeshFileWriter::setInteriorIndex function, for control of interior material.
• Cutout and cut fracture methods: NvBlastExtAuthoringCreateCutoutSet and Nv::Blast::CutoutSet API, FractureTool::cut and FractureTool::cutout APIs.
• NvBlastExtAuthoring:
  • NvBlastExtAuthoringCreateMeshFromFacets function.
  • NvBlastExtUpdateGraphicsMesh function.
  • NvBlastExtAuthoringBuildCollisionMeshes function.
• UV fitting on interior materials using new FractureTool::fitUvToRect and FractureTool::fitAllUvToRect functions.
• Multi-material support in OBJ file format.

Bug fixes

• Fixed bug causing normals on every other depth level to be flipped when exporting Blast meshes.
• Fixed bug where faces are missed after hierarchy optimization on a sliced mesh.
• Fixed subtree chunk count generated in Nv::Blast::Asset::Create (led to a crash in authoring tools, fracturing a pre-fractured mesh).
• Fixed a crash when loading an obj with bad material indices.
• Fixed Actor::split so that visibility lists are correctly updated even when the number of split actors exceeds newActorsMaxCount.

Known Issues

• Damage shaders in extensions can miss bonds if the damage volume is too small.
• Authoring code does not use the user-defined allocator (NvBlastGlobals) exclusively.
