Skin is a texture image that replaces the default skin of your avatar. Skins can be re-made and uploaded in Sine Space using the Virtual Goods component.
You can download the default avatar skin template from the following link.
Once you have created the Skin save the PSD and import it back to Unity.
Unity uses a working folder called the "Assets Folder" - anything in this folder is accessible in Unity in the 'Project' panel. You can right-click in the 'Project' panel, and select 'Show in Explorer' (or 'Show in Finder' on MacOS) and view the files. To import the texture into Unity, simply save it into this folder. Unity will detect and import the texture when you tab back into it.
Attention: Do not store the edited Skin in the 'Artist Project' folder, it will not be uploaded. (That folder is ignored during uploads)
A skin is a special type of Clothing Item - as of Editor Pack 12, we strongly recommend uploading skins using the new 'Tattoo System' which is documented below.
Video Option: This topic is covered under Masterclass 17
Create a new blank gameobject using GameObject->Create Empty from the menu
On the right hand side of the screen, locate the "Inspector" panel, and add a Clothing Item Settings component to this new empty object
Locate the Tattoo section on this component
You now need to adjust the settings to indicate this is a skin; the key settings are:
NOTE: If you are using an older Editor pack, you will also need to tick 'Only Contains Skin' to get it to process correctly, you can find that on the Skin tab. (Newer editor packs such as 12p13 should not require this; however if you encounter an error during processing, you may want to try it.)
The next step is to format it as a item - fill in details on the name, pricing, etc.
Add the virtual good component from the 'Add Component' button
You will then need to adjust some settings - fill in the form until all the red exclamation marks have vanished.
Finally, to save this to disk (so that it is stored as a file, versus simply an object in your scene), click the 'Fix Now' button to convert it to a prefab; be aware the objects name (at the top) will be used in the filename, so you may want to rename the object prior to clicking this button.
You may now upload the item from the Upload tab, this will upload it to the world directly.
If you wish to preview it, prior to uploading; you can use the Clothing Previewer to test an item
Create a new GameObject
Add the Statue and Clothing Previewer components to the object
Now, in the Project Panel, locate your object
You can then drag the object into the previewer slot. Set the appropriate gender on the 'Statue' component (note: the Statue component can be used for NPCs, or previewing against a specific avatar - see more in the NPC pages of this wiki)
Hit the 'Play' button in Unity, and the avatar should preview, while wearing the item.
If you need to use a custom shader or material for your skin, follow this procedure. Note this method may not be as compatible with tattoos and makeup layers.
you can create a new material and drag skin texture and normal map in normal map slot.
Once the material is created you can chose the material shader for skin from built in unity standard, custom shader or SineWave skin shader.
SineWave Skin Shader
Once the skin material is created, it needs to be converted to fit the skeleton.
Create an empty game object in the scene and add the Clothing Item Settings Component to it.
Chose the relevant Skelton for the clothing item. Please note Space supports multiple third party skeletons as well as it's own native male and female models.
If you are creating only skin, select Skin Base slot. If you want the skin to have more than just skin select other applicable slots.
Select Only contains skin if you are uploading skin only. If you are doing a combined outfit Don't select this.
Set the number of material the skeleton you are using has.
Sine Space male and female skin only has 1 material; if you have selected that as the skeleton Set the size to 1.
After the size is set. Drag the skin material in the material slot.
Attach the virtual goods script and complete the submission process.
See Virtual Goods for more details on the virtual goods script.
