Modeling Guide

First download the latest version of HSDRAW. Open a .dat file, and in Nodes on the left-hand side expand scene_data until you see the RootJoint. Double click on the RootJoint to open the model.

Expand Root Joint

Objects

Models have Objects. Objects can be hands, heads, limbs, etc. Two interesting objects include the Shadow Dummy and the Shadow Outline.

Shadow Dummy

The Shadow Dummy is a blocky shadow outline of the character. This appears to be used for the shadow on the ground. It is likely flattened when creating the shadow in-game.

There is also a Shadow Outline.

Shadow Outline

These objects use Back-face culling to create a dark outline on the model. Back-face culling makes the polygons facing the camera invisible, but leaves the polygons behind them visible. This guarantees that the model itself will always be over the Shadow Outline polygons.

Export

You can export the model, allowing you to modify it in external programs like Blender. Go to File->Export Model to File

Export Model to File

Export it as a .dae file. It is recommended to create a new folder for the output, as it will also save the respective textures used for the model.

The default settings should be fine, although you may want to select any settings that seem relevant.

Export Settings

Import

After done modifying the model, you can re-import it at File->Import Model From File

Import Model From File

Once again, the default settings should be fine. It is recommended to keep the current skeleton if you get a warning for it.

Import Settings

Note that many of the object properties will be changed. This is because the export format does not store these properties. You will need to compare each object to the original object properties and fix them.

Update Culling

After you've compared to the original model and fixed the object properties, you may notice that the new model still doesn't appear to match the original.

Model Not Matching

At this point you will need to change the culling on many objects. HSDRAW gets confused and thinks the original model has Front culling on all objects, but the objects are instead a mix of None and Back:

  • Object 0 - None Culling
  • Object 1 - None Culling
  • Object 2 - None Culling
  • Object 3 - None Culling
  • Object 4 - None Culling
  • Object 5 - None Culling
  • Object 6 - None Culling
  • Object 7 - None Culling
  • Object 8 - None Culling
  • Object 9 - None Culling
  • Object 10 - Back Culling
  • Object 11 - None Culling
  • Object 12 - Back Culling
  • Object 13 - Back Culling
  • Object 14 - Back Culling
  • Object 15 - Back Culling
  • Object 16 - None Culling
  • Object 17 - Back Culling
  • Object 18 - Back Culling
  • Object 19 - Back Culling
  • Object 20 - Back Culling
  • Object 21 - Back Culling
  • Object 22 - Back Culling
  • Object 23 - Back Culling

The idea being, shadows should only be visible in Back of non-shadows. This creates the illusion of cell shading.

The model should now roughly match the original in HSDRAW:
