Question by Ogdy · Jul 06, 2016 at 04:14 PM · meshmaterialruntimeuvobj

Issue with materials on runtime-loaded mesh.

Hello,

I have a very weird issue : I am using the wiki's .obj runtime importer (http://wiki.unity3d.com/index.php?title=ObjImporter)

My .obj files have no uv. However, I should be able to -at least- set uniform colors to models once they are imported. What happens is that all the .obj I import with this script are completly black when I add a diffuse shader with a color to them.

I have no clue of what is happening. The issue seems to come from the generated mesh itself (maybe the UV?).

Do someone knows what is happening here ? Thanks in advance.

Here is the code that calls the ObjImporter : GameObject newobject = new GameObject();

  if (!string.IsNullOrEmpty(path))
  {
        Mesh holderMesh = new Mesh();
        ObjImporter newMesh = new ObjImporter();
        holderMesh = newMesh.ImportFile(path);
  
        newobject.AddComponent<MeshRenderer>();
        MeshFilter filter = newobject.AddComponent<MeshFilter>();
        filter.mesh = holderMesh;
  
        newobject.GetComponent<Renderer>().material = Resources.Load("Materials/Default", typeof(Material)) as Material;
   }
