How to Import

.dae

• Xcode an read this. Just drag it into your art.scnassets folder.

.blend

• If the model in .blend format, open it in Blender, and export it as a .dae.
• Create a folder in art.scnassets for your model(s) and texture(s)
• Drag the .dae and the textures (.jpg or .png) into your folder
• If there are textures, click the .dae scene, find the model you want, and select the texture image in the diffuse section of the model.
• Add a the model as an SCNNode to your scene.

func rootNodeFromResource(assetName: String, extensionName: String) -> SCNNode {
    let url = Bundle.main.url(forResource: "art.scnassets/\(assetName)", withExtension: extensionName)!
    let node = SCNReferenceNode(url: url)!

    node.name = assetName
    node.load()
    return node
}

let potionsRoot = rootNodeFromResource(assetName: "potions/vzor", extensionName: "dae")
let potionNode = potionsRoot.childNode(withName: "small_health_poti_blue", recursively: true)!
scene.rootNode.addChildNode(potionNode)
