Question Why Custom Render Texture not Showing on Material?

I'm having this issue, that I'm unable to render the Custom Render Texture to an object
As you can see below the material just appear as transparent, but the MainText is showing (and doing what is supposed to)


The material (LastMaterial) shader is as follows:

I don't know why it's not showing even as the MainTexture is ok
Any help is welcome

 

I finally got it working, even as it took the first texture from a texture2d it was not using the wrap sampling of the texture, but rather "Clamp"
