Getting UV coordinate with GraphicRaycaster

Same problem here... :(

Hi @TurboHermit!

This is was posted long time ago, but this is a solution I've found using the RectTransformUtility:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 using UnityEngine.EventSystems;
 
 public class Test : MonoBehaviour
 {
     private GraphicRaycaster graphicRaycaster;
     private EventSystem eventSystem;
     private PointerEventData eventData;
 
     void Start() {
         //The GraphicRaycaster component in the Canvas
         graphicRaycaster = GetComponent<GraphicRaycaster>();
         //The EventSystem in the Scene
         eventSystem = GameObject.Find("EventSystem").GetComponent<EventSystem>();
     }
     
     void Update()
     {
         if (Input.GetMouseButtonDown(0)) {
             //Create a PointerEventData to pass in the Raycast
             eventData = new PointerEventData(eventSystem);
             eventData.position = Input.mousePosition;
             //Create a RaycasResult list to pass in the Raycast
             List<RaycastResult> results = new List<RaycastResult>();
 
             graphicRaycaster.Raycast(eventData, results);
             
             foreach (RaycastResult result in results)
             {
                 //Check if you hitted the image
                 if (result.gameObject.name == "your image name") {
                     Vector2 localPosition; //the local position in the image Rect coordinates
                     RectTransform rectTransform = result.gameObject.GetComponent<RectTransform>();
                     
                     //This obtains the position of the pointer in the image rect coordinates
                     RectTransformUtility.ScreenPointToLocalPointInRectangle(rectTransform, 
                     eventData.position, Camera.main, out localPosition);
 
                     Debug.Log(localPosition);
                 }
             }
 
             
         }
     }
 }
