zbrush import Vertex Color rgb

hi about zbrush export Vertex Color rgb
i have make try with little cube and see on block note what's we can read about him
the goal is reimport this in unity i looking on the web and i'm surprised of found nothing about this
so all help is welcome for sure

 

i have start here


someone have time to look please

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5.  
6. public class zbrush : MonoBehaviour {
7.  
8.     public string test;
9.     public Color testco;
10.    
11.    
12.     // Use this for initialization
13.     void Start () {
14.  
15.         //testco = HexToColor (test);
16.         //ArrayList arr =new ArrayList (test.);
17.  
18.         int length = 8;
19.         int strLength = test.Length;
20.         int strCount = (strLength + length - 1) / length;
21.             string[] result = new string[strCount];
22.  
23.         for (int i = 0; i < strCount; ++i)
24.         {
25.             result[i] = test.Substring(i * length, Mathf.Min(length, strLength));
26.             strLength -= length;
27.           }
28.         // result
29.         //foreach(string f in result)
30.         //     Debug.Log(string.Format("[{0}]", f));
31.  
32.  
33.         Mesh mesh = GetComponent<MeshFilter>().mesh;
34.         Vector3[] vertices = mesh.vertices;
35.         Color[] colors = new Color[vertices.Length];
36.  
37.         Debug.Log (vertices.Length+"  dd  "+result.Length  );
38.        
39.         int i2 = 0;
40.         while (i2 < vertices.Length) {
41.             colors[i2] =    HexToColor (result[i2].Substring(2,6))  ;   //Color.Lerp(Color.red, Color.green, vertices[i].y);
42.             i2= i2+2;
43.         }
44.        
45.  
46.  
47.  
48.         mesh.colors = colors;
49.  
50.     }
51.  
52.  
53.  
54.  
55. Color HexToColor(string hex)
56.     {
57.         byte r = byte.Parse(hex.Substring(0,2), System.Globalization.NumberStyles.HexNumber);
58.         byte g = byte.Parse(hex.Substring(2,2), System.Globalization.NumberStyles.HexNumber);
59.         byte b = byte.Parse(hex.Substring(4,2), System.Globalization.NumberStyles.HexNumber);
60.         return new Color32(r,g,b, 255);
61.     }
62.  
63.     // Update is called once per frame
64.     void Update () {
65.    
66.     }
67. }
68.  
69.  

 

so what's happen i got [vertices.Length] is two length of color
so only 1/2 is colored and it's not look on good vertex order
someone can help please

 

i found this it's maybie one way for do it more accurency

http://wiki.unity3d.com/index.php/ObjImporter

but i fear it's not to my level string reader look to mutch

anyone can help please

 

I would see if you could convert that OBJ to FBX outside of Unity. Unity certainly does support loading vertex colors from FBX.

 

thank's i have already try this way but yes maybie she exist somethink's for sure

 

Use FBX, then use a shader that supports vertex colours.

 

Zbrush don't export on FBX
but if get full info how do it
very interessing by the way

 

You can use Blender to import the OBJ and export an FBX.

 

thank's i try now

 

Not Working here any option in blender for import vertex color from zbrush i have make check

 

OH my god i think's i do it after try with Goz for blender ! oh can say how i many thank's
