Vray - Copy texture channel ?

[Lilarcor]

Hello,

I'm sure this must a noob question, pardon me for this. I used vray in other applications,so the principles must be same here right?

Can you tell me how do you copy a texture channel to another? For example you setup your diffuse channel by mixing some textures and procedurals. Now how do you copy this to another channel like bump, or another material's diffuse for example? Do I have to start all over? This makes tiling and such a pain.

Thank you
