Pay for Unity 4.6 render to texture?

Unity Engine
1

I have to use a plugin that is only compatible with Unity 4.6, and at the same time I need to use render to texture which I believe is a feature that used to be in the paid version only.

Recently Unity changed the licensing model though, so that all features are unlocked no matter if you use pro version or not. But, seems it is still locked in the 4.6 version? How does this work exactly, any way to unlock this feature in 4.6 for the basic license, or you still have to pay for that if you use an older version of Unity?

The change to the licensing model only affects Unity 5.0 onwards. If you want to use render-to-texture in Unity 4.6, you are still required to buy a Pro license.
