SCNNode material scale

I have an SCNNode that has its geometry populated from a collada file (.dae) and displays correctly on screen. I can apply materials to the geometry easily enough, however I'd like to change the scale of the material.

I currently populate it with

nodeArray[0].geometry?.firstMaterial!.diffuse.contents="wood.png"

but the scale of the material is too small. While I can edit the png in GIMP or something similar and import it as wood2.png is there any way I can set the material scale programatically?

Solution

  • You need to open your UV snapshot in an image editing software like Photoshop, scale the wood texture in Photoshop over your UV's, then resave your PNG/JPG, move PNG/JPG back to Xcode
