c# - How to set up UVs for Texture borders -

i'm generating plane able scale without edges of texture being affected pixel wise. plane needs able keep border proportion able stretch size. mesh has 8 vertices , 10 triangles make border. anyway here get. ignore numbers on mesh geometry.

is possible edit uvs desired result? here's code:

mesh mesh = new mesh();     var renderer = mesh.addrenderer();       //create verticies      mesh.vertices = new vector3[] {          //vertices in order convienience          manager.gui.screentoworldpoint(new vector3(0f,0f,0f)),                            //0         manager.gui.screentoworldpoint(new vector3(padding,padding,0)),                   //1         manager.gui.screentoworldpoint(new vector3(width - padding, padding,0f)),         //2         manager.gui.screentoworldpoint(new vector3(width,0f,0f)),                         //3         manager.gui.screentoworldpoint(new vector3(width - padding, height - padding,0f)),//4         manager.gui.screentoworldpoint(new vector3(width,height,0f)),                     //5         manager.gui.screentoworldpoint(new vector3(padding, height - padding, 0f)),       //6         manager.gui.screentoworldpoint(new vector3(0f,height,0f)),                        //7     };        //create triangles     mesh.triangles = new int[] {         7,5,6,         6,5,4,         4,5,3,         2,4,3,         0,2,3,         0,1,2,         0,7,6,         0,6,1,         1,6,4,         1,4,2 };      //create uv's uvs in order of creation convienience        mesh.uv = new vector2[] {            new vector2(0f,0f),            new vector2(padding/width, padding/height),            new vector2((width-padding)/width, padding/height),            new vector2(1f,0f),            new vector2((width - padding)/width,(height-padding)/height),            new vector2(1f,1f),            new vector2(padding/width,(height-padding)/height),            new vector2(0f,1f)          };        mesh.calculatenormals();     mesh.calculatebounds();     renderer.texture = mytex;     return plane; } 

padding defined pixels around the texture ignores scaling, while height , width dimensions of shape.

as george said, mesh generating made impossible to scale image without interesting. fix the mesh had remade works. code now

mesh mesh = new mesh();     var renderer = mesh.addrenderer();          mesh.vertices = new vector3[] {                  //vertices in order convienience                   manager.gui.screentoworldpoint(new vector3(0f,0f,0f)),                            //0                 manager.gui.screentoworldpoint(new vector3(padding,0f,0f)),                      //1                 manager.gui.screentoworldpoint(new vector3(padding,padding,0)),                   //2                 manager.gui.screentoworldpoint(new vector3(width - padding, 0f,0f)),              //3                 manager.gui.screentoworldpoint(new vector3(width - padding, padding,0f)),         //4                 manager.gui.screentoworldpoint(new vector3(width,0f,0f)),                         //5                 manager.gui.screentoworldpoint(new vector3(width,padding,0f)),                    //6                 manager.gui.screentoworldpoint(new vector3(width , height - padding,0f)),         //7                 manager.gui.screentoworldpoint(new vector3(width - padding, height - padding,0f)),//8                 manager.gui.screentoworldpoint(new vector3(width,height,0f)),                     //9                 manager.gui.screentoworldpoint(new vector3(width - padding,height,0f)),           //10                 manager.gui.screentoworldpoint(new vector3(padding, height, 0f)),                 //11                 manager.gui.screentoworldpoint(new vector3(padding, height - padding, 0f)),       //12                 manager.gui.screentoworldpoint(new vector3(0f,height,0f)),                        //13                 manager.gui.screentoworldpoint(new vector3(0f,height - padding,0f)),              //14                 manager.gui.screentoworldpoint(new vector3(0f,padding,0f)),                       //15             };                //create triangles             mesh.triangles = new int[] {                 15,2,0,                 1,0,2,                 1,2,4,                 1,4,3,                 3,4,6,                 3,6,5,                 4,8,7,                 4,7,6,                 8,10,9,                 8,9,7,                 12,10,8,                 12,11,10,                 14,11,12,                 14,13,11,                 15,14,12,                 15,12,2,                 2,12,8,                 2,8,4      };              //create uv's uvs in order of creation convienience                mesh.uv = new vector2[] {                    new vector2(0f,0f),   //0                    new vector2(padding / width, 0f), //1                    new vector2(padding/width, padding/height), //2                    new vector2((width-padding)/width, 0f), //3                    new vector2((width-padding)/width, padding/height), //4                    new vector2(1f,0f), //5                    new vector2(1f,padding / height), //6                     new vector2(1f, (height - padding) / height), //7                    new vector2((width - padding)/width,(height-padding)/height),//8                    new vector2(1f,1f), //9                     new vector2((width -padding)/width,1f), //10                     new vector2(padding/width,1f), //11                    new vector2(padding/width,(height-padding)/height), //12                    new vector2(0f,1f), //13                    new vector2(0f,(height - padding) / height), //14                    new vector2(0f,padding / height) //15                  };                mesh.recalculatenormals();             mesh.recalculatebounds();              return plane;
