Save Changes to DAE file in Scenekit


So I’ve abandoned the isea of using google vr for now and i’m trying to modify the mixed reality scenkit project. it’s really close to what i need but if i import a .dae model from blender it doesn’t have the textures i want but when i modify the material in xcode it won’t save? how do i change this.
also, how would i use a particle system instead of the meshes in the mixed reality project?


ok so i got round this by converting to a scn file but now i get code sign errors when i change stuff from the original project. driving me nuts!


basically whenever i add a texture - 1024x1024 png just like tree


That’s weird you’re getting code sign errors on changing stuff. What’s Xcode failing to code sign?
