Character Creation Insight From Gilbran

1. Base Body

1. (Artist) Base Body Setup

   1. skin and model thoroughly as a baseline

2. (Artist) Set Blend Shape and Shape Keys

   1. define min max size
   2. Topologi jangan sampe ada yang berubah

   

   

3. (Programmer) Integrate Blend Shape with the Game

   

4. (Program)Bone Scaling

   

2. Clothing and Accessories

1. (Artist) Create Costume based on base model

1. (Artist) Separate Parts

   1. Export with bone (Based on Base) [Research Point ?]

   

2. (Program) Transfer Bone from accessories to base skin bone

   1. this way accessories got properly attached to the bone

   

3. (Artist / Programmer?) Fitting Accessories to character looks

   1. using shrink wrap
   2. additional adjustment in maya to configure wrapping (Tedious) [Research Point? ]

   

   

   

Problems

Mesh Normal Overlapping (head and body is separate part)

Tips : (Maya) Transfer Attribute (merging 2 different mesh to 1 mesh)

3. Animation

Much Easier since animation is bound to skeleton since skeleton is re-used multiple times

kesulitan adalah untuk bikin gear yang nggak clipping ketika animasi

• nggak mungkin keliatan di depan. karena kesulitan ngecek 1-1 untuk semua case

Q&A :

• Nicko ngehindarin Blend Shape. dikarenakan tedious

  • tapi oke karena semua karakter punya badan yang sama
  • blend shape di rekomendasikan untuk re-using armor model asset ke different body type
  • alternatif lain, pakai vertex shader extrusion untuk mengubah bentuk badan (dari normal ke gemuk), tapi jadi perlu ada tambahan texture channel untuk menentukan extrusion valuenya. Advantage : extrusion map bisa ditransfer/dimapping dari body ke armor/cloth

• kapan prefer pake shape key (blend shape) atau kapan pake bone untuk scaling2 nya

  • untuk AAA pakai 2 2 nya tapi practice nya juga perlu di kontrol
  • untuk objek statis nggak perlu shape keys.
  • untuk objek yang nggak ada bone nya preferrably pake shape keys
  • tapi untuk objek yang animated preferrably pake bone

• Changing base model mid development

  • unbind model from old bone (copy weight information)
  • bind model to new bone (paste weight information)
  • adjust weight information

• scalability untuk nambah slot aksesoris tambahan

  • Add attachment points that’s parented to corresponding bone.
  • Some static attachments doesnt need to be rigged (Hats, short-hairs, glasses, helms, etc)
  • Some attachments might need their own skeletal rig to be procedurally/programmatically animated (Long hair, capes, earrings, weapons, shield, etc)
  • Some attachments need to be rigged to the body skeleton (moustache, beard, gloves, shoes, etc)

• cape yang berkibar2 what to use ?

  • either using Cloth Physics or Jointed Bones Physics Cloth Physics :

    • Built in function
    • might not works when switching mesh programmatically

    Jointed Bones Physics

    • Easier to set up
    • Need to add script to simulate physics

  • kasih bone ke semua model meskipun nggak ke apply [ can procedural animation helps ?]

• UV Mapping sama untuk badan nya.

• aksesoris bone terpisah

• jubah dan yang nempel banget sama pakaian untuk badan nya.

• standarisasi

• equipment yang jadi 1 sama badan nya

• standarisasi untuk rig
