Scene Cache

[i-saint]

Unity / MeshSync

• [x] make a component that opens cache files and sends data via TCP. MeshSyncServer is intact in this phase.
• [x] make a local version of MeshSyncServer. stream data directly from cache files (no TCP connection).
• [x] create animation clips
  • all frames have key and interpolation is constant. (make skipping specific frames easy)
  • timeline support will be done with this feature.
• [x] 'copy .sc to StreamingAssets' button
• [x] interpolation
• [x] make prefab when import cache
• [x] make scriptable importer for cache files
• [x] animation frame rate override functionality
• [ ] show better error messages (than "Invalid AssetDatabase path")
• direct GPU buffer update
  • [ ] d3d11
  • [ ] d3d12
• [ ] preload options
• [ ] generate velocity
• [ ] cache recorder (exporter for Unity)
• [ ] bake skinning functionality for MeshSync side

DCC

• [x] (max) cache exporter CUI
• [x] (max) cache exporter GUI
• [x] (max) export meshes after TurboSmooth applied (export render meshes)
• [x] (max) face group ids
• [x] (max) strip unused materials
• [x] (max) remove '3ds Max opt' from externals
• [ ] (max) submaterial name (parent name _ sub name)
• [ ] (max) custom view matrix (for tilt correction)
• [ ] (max) export meshes that have multiple render meshes (particeles, etc)
• [ ] (max) use camera/light state.
• [x] (maya) cache exporter CUI
• [x] (maya) cache exporter GUI
• [x] (maya) 'bake transform' option
• [x] (blender) cache exporter CUI
• [x] (blender) cache exporter GUI
• [x] (blender) 'bake transform' option
• [x] (blender) mesh instance with 'bake transform'
• [x] (blender) export selection
• [x] (modo) cache exporter CUI
• [x] (modo) cache exporter GUI
• [x] (modo) 'bake transform' option
• [x] (modo) mesh instance with 'bake transform'
• [x] (modo) export selection
• [ ] (mobu) lens shift
• [ ] Alembic to scene cache
  • USD have Alembic plugin and can read .abc transparently. but it doesn't recognize some important properties (FaceSets, vertex colors which many DCCs support with their own extension attributes).
• [ ] USD to scene cache

optimization

• [x] strip unchanged vertex attributes
• [x] pre-convert (serialize refined meshes)
• [x] 'flatten hierarchy' mode
• [x] add meta data (just like topology variance in Alembic)
• [x] preload
• [x] (unity) use MeshRender if the Mesh is not skinned
• [x] use decoded scene buffer as vertex buffers directly (avoid large buffer copy)
• [x] split scene buffer & parallel decode
  • [x] equalize vertex count per split
• [x] SIMD-ify lerp tangents/normals
• [ ] (unity) use NativeArrayUnsafeUtility.ConvertExistingDataToNativeArray()
  • on Unity 2019.3, Mesh can accept NativeArray vertex buffer
• [ ] per-vertex-attribute data update flags
• [ ] normal/tangents compression
  • x, y, sign (1 bit)
• [ ] 'merge into monolithic mesh' mode
• [ ] use memory-mapped files

misc.

• [ ] interpolate matrices (MeshRefineSettings)
