How to get 3D world space position from Render Texture
<p>I am using  <a href="http://docs.unity3d.com/Manual/class-RenderTexture.html" rel="nofollow noreferrer"><strong>Render Texture</strong></a> to make a <strong>Side Map</strong>, it is working fine and I have made it through these steps.</p>

<ol>
<li>One Main Camera Rendering the Scene.</li>
<li>NGUI Camera Rendering the GUI.</li>
<li>That GUI contains the Render Texture (minimap) which rendering the scene on the texture using GUI Camera.</li>
</ol>

<p><strong>But</strong> now I want to improve the map further and want it to make intractable. I want world space position from Render Texture click point. <strong>Is there any way available that I get world space position from render texture's specific click point?</strong></p>

<p>If I click somewhere in render texture then, how can I get the point in 3D world space. </p>

<p><em>For example: I clicked a car object on Render Texture. Now, how can I highlight or get it in 3D world space.?</em> How can Convert 2D render texture click position to World Space Position!</p>
