Create a Texture Isntance or Something (RENDER TARGET)

Hi,

I using a Texture to RenderTarget for the Sniper Scope. This works well, but i grab two Sniper in each Hand, the two scopes show the same. I only apply the material with Render Target on the grab the weapon.
In multiplayer, the player who pick first happen the same.

What is the way to do this?

Is any way to Instance the Render Target? I need to create each Render Target Texture as many players in the server?

Thanks and sorry my english.

Regards!
