Set Uvs Coordinates[SOLVED]

[jeanfabre]

Hi,

 It works here, I think you are simply not properly setting the base values, so it doesn't match any uvs.

bye,

Very strange!

I pay attention to basic values ​​(here uv base values ​​of the cube)

Another strange thing , the values ​​displayed by UV "mouse pick uv" remains that of the original mesh and does not change when I move the uvs while the texture changes color!

[jeanfabre]

Hi,

 your uv values showned for the cube are wrong, uv ranges from 0.0 to 1.0, so what script are you using the get these values?

bye,

 Jean

[logiquefloue]

This is an imported cube Blender, the script told me exactly the same values ​​as in Blender.

Here is the script

Code: [Select]

#pragma strict
 
public var theCube : Transform;
private var theUVs : String = "";

function Start ()
{
    if (theCube == null)
        theCube = this.transform;
 
    var theMesh : Mesh = theCube.GetComponent(MeshFilter).mesh as Mesh;
     
    theUVs = theUVs + "(" + theMesh.uv.length.ToString() + ") :";
     
    for (var i:int = 0; i < theMesh.vertices.length; i ++) {
       
        theUVs = theUVs + "  " + i + "=" + theMesh.uv[i].ToString();
       
    }
}
 
function OnGUI ()
{
    GUI.Label( Rect( 10, Screen.height * 0.25, Screen.width - 20, Screen.height * 0.25), "UVs " + theUVs );
 
}
Having said that, with the following script, I can move my UVs ... but when I use "mouse select uv'' to the new coordinates, it does not work, I always start UV coordinates, have you any idea? Merci

Code: [Select]

#pragma strict
 
public var theCube : Transform;

function MoveUV_1 ( UVf : float)
{
     if (theCube == null)
        theCube = this.transform;
 
    var theMesh : Mesh = theCube.GetComponent(MeshFilter).mesh as Mesh;
  var UVs : Vector2[] = new Vector2[theMesh.uv.Length];
    UVs = theMesh.uv;
   
 for (var i:int = 0; i < theMesh.vertices.length; i ++) {
 
 if (UVs[i].x == 0.1){
       
  UVs[i] = Vector2 (0.1, UVf);
  }
 
 theMesh.uv = UVs;
             
 
  }
     
}

Hi,

 Then, pm me with this object and your scene if you can, cause it works ok with all the tests I carried over.

bye,

Hi,

Here the scene.

Reminder of malfunctions:

1 / If UV base is defined, the coordinates UV targets are defined in 0.0
2 / When I move the uv,  "Mouse Pick UV" always gives my old coordinates and not the news!

[jeanfabre]

Hi,

 You need to package the scene, otherwise, I won't have the model and the texture.

bye,

 Jean

[logiquefloue]

sorry

Here the package

[jeanfabre]

Hi,

 Ok, thanks, I could find the problem! Thanks for the scene, it helped me finding what exactly I was doing wrong in my tests. Can you redownload from the original post, ti should work fine now.

bye,

 Jean

[logiquefloue]

It works fine now, thanks 

The new coordinates are not displayed by "pick mouse UV" do you know why?

[jeanfabre]

Hi,

 Maybe you should wait one frame, the mesh update cycle maybe not done yet.

bye,

 Jean

[logiquefloue]

Hi Jean,

Uv pixel is set to "every frame". the strange thing is that the texture changes is OK (that means that the mesh is updated, right?) but we still have the old UV coordinates! The problem is visible on the package that I sent yesterday.

Thank you for your help.

[jeanfabre]

Hi,

Try to put a mesh collider on the cube. A box collider will not work.


bye,

 Jean

[logiquefloue]

Even with <Mesh collider> I do not have the new UV coordinates, and the old coordinates are displayed <Mouse Pick Uv>!
I think <Mouse Pick Uv> ignores changes to a mesh prefab in real time (execution)!

thank you

[jeanfabre]

Hi,

 Good catch, What happens is that editing a mesh can be done locally, or actually to the mesh on the asset folder ( the shared mesh), and then ALL components using this mesh will actually see the changes.

Redownload the action, it nows has options to "Affect shared mesh" when you set UV.

Bye,

 Jean
