  • UV Layout
    • Connectivity
      • Seperate Edges - 액자같은거 Group으로 edge잘라서
      • Island Attribute - Copy같이 여러개 만들었을때 attribute 만들고 unpack (transfer attribute)하고

udim https://www.sidefx.com/docs/houdini/solaris/udim.html UDIM is a system for dividing texture space into multiple “tiles” in UV space, with each tile represented by a separate texture file on disk.

  • 1001 기준
    • 1만큼 옆으로(U)
    • 10만큼 위로(V)
