Help:Replacing models: Difference between revisions

*(optional) If you are using 3ds Max, the [https://github.com/Aaaboy97/BotW-Tools/tree/master/CSV%20Exporting CSV export] script

<blockquote>Summary: Import the DAE into a shared workspace with your model, so that the object list has your objects, the original objects, and the original skeleton.</blockquote>Open your 3D modeling program of choice, and bring your replacement model into the workspace. Then, go to File -> Import, and import the DAE model you extracted from the SBFRES. If you exported multiple models, only import the model you are currently working with. For example, if you exported an entire armor, you should only import the legs (or whatever part you are working with). Once you have finished the "Export Your Rigged Model" step, return here to repeat the process for other models.

You may see errors when you import with 3ds Max - this is normal, you can ignore them. Blender suppresses these errors, so you won't see them.

Combine the original model's objects, roughly along the lines of how your objects are. For example, if the original model has separate fingers, hands, and arms, and your model has separate hands and arms, combine the fingers with the hands. Or if your model is only a single object, combine all the original model's objects into a single object. In 3ds Max, you can do this with Command Panel -> Modify -> Edit Geometry -> Attach, and selecting the object to attach the selected object to. In Blender, you can do this by selecting multiple objects with Ctrl+click in Object mode, then right-clicking and selecting Join.

There are also plenty of tools in 3ds Max's Edit Poly/Mesh modes, or Blender's Sculpt mode for helping move the model around. In 3ds Max, you can right click on the Edit Mesh/Poly to convert between them. In Blender, one of Sculpt mode's tools is the Pose tool, which is quite good for moving limbs into place if you're modifying an armor.

Rename your objects to something close to the original's, so that you can easily figure out which of your objects corresponds to which original object. This will help both during this step and later, during the "Replace the Original Model with Yours" step. For example, if you have an object for hair, it's encouraged to name it <code>Hair_###__Mt_Hair_###</code>, where ### is the number of the armor you might be working with, and Mt_Hair_### is the name of the material you want to use with it. Including the name of the material in the object is helpful so that when you need to reassign materials in Switch Toolbox (which you may have to do often, depending on how much trouble you have) you will be able to tell, straight away, which object needs which material.

===Apply the Rig from the Original to Your Model===

<blockquote>Summary: Apply the rig from the original object(s) to your object(s). Set maximum limit for bones to affect vertices to the object's skin count.</blockquote>For 3ds Max: Select the original object's Skin modifier in the modifier list, then copy it. Select your object, then paste the rig onto it. If all has gone well, you're done with this step. 3ds Max uses one or more of a series of algorithms to map the rig of one object onto the rig of another object automatically, and it's generally pretty good about it.

 

After applying the rig onto an object, set the limit for the number of bones to affect each vertex to 4. In 3ds Max, you can do this by scrolling the modifier rollout on the right side down to the bottom, expanding Advanced Parameters, and setting the number in the Bone Affect Limit box. In Blender, you can do it with the Limit Total option, found right under the Transfer Weights option described earlier. Other programs will have different ways of setting this limit.

 

You also want your weights to be normalized. In 3ds Max, the weights are normalized by default. In Blender, in Weight Paint mode, you need to click on the screwdriver-and-wrench icon in the middle of the right side, expand Options, and select Auto Normalize.

<blockquote>Summary: Delete the original model's objects and your model's skeleton (if any), leaving just your objects and the original skeleton. Rename your objects.</blockquote>Delete all the objects from your workspace that you don't want to be imported to the game. This includes any secondary objects not part of your final model, your model's skeleton (but not the original model's skeleton), and the original model's objects.

It's also a good idea to rename the your objects to names that describe what they are for. In Blender, renaming the upside-down orange triangle doesn't do it, you have to expand that and rename the upside-down green triangle. Though this isn't strictly necessary to get the replacement model to work, it can really help smooth things out later.

<blockquote>Summary: Fairly simple, export your model. DAE is probably best.</blockquote>Using File -> Export, export your model as whatever type you wish. Switch Toolbox, as of writing this guide, only handles DAE properly. It has an option for FBX as well, and as it receives updates regularly, FBX or other formats may become properly handled at any time.

It also has an option for importing via CSV (which is not a model type) that is explained in the optional step, below. CSV is only recommended if your exporter cannot export DAE or FBX for whatever reason.

Switch Toolbox now handles DAE's from Blender just fine, so there is no longer any need to use Autodesk FBX Converter, as was originally described here.

Eyes are very strange. Link's original eyes are placed correctly, but exporting them will cause them to be placed incorrectly in any 3d modeling program, and reimporting unchanged eyes will cause them to appear in a different place. However, the game will load them as if they were in the correct place. It is generally not advised to move the eyes unless absolutely necessary, as there is no single way to make them work consistently.
