Using layer as mask

Hi all!
I was looking for a way to use a layer as mask for another one. It's what i did with render target in V4. Browsing throw the manual I've noticed that should be a button named Chroma Keyer Rank in the layers tab which actually there is not, or better I didn't found.
Anyway my questions are:
How I can do that?
or
Is there a way to obtain a layer content as texture?
and
What procedure is supposed to be substitute of the v4 render target functions?

Thanks
Ale

You can switch any layer to become an "Offscreen Render Target".

Simply click the "Layout" in the 3D Layer
then choose "Offscreen Render Target" instead of "Full Size"

Fantastic! Thank you.
I didn't think to look into layout properties for that. :P

All the best

Hi,

I was just looking for the same feature but couldn't find a way to get the 'Offscreen Render Target' as Texture for a second layer.
Can you tell me the trick?

thanks

I'm wondering how to do this myself. Can someone please explain how to use a Layer that has been designated as an Offscreen Render as a texture in another Layer?

I was assuming it was in the Material node as per the documentation, but I don't see where to link to the Offscreen Layer...

Unfortunately this is far from intuitive! But you're on the right path. Set it to Texture Property Empty. Now you've got a texture slot. Expose it. On Layer level bind the exposed texture property to the render target's texture property.
