How to hide object from rendering?

I have a scene with 4 four object and I want to hide one of them and I don’t how…I want to render only three of them at first…
There is four groups in my egg file…
“Red”,“Blue”,“Green”,“Yellow”
Red and Blue have group in egg file.
I used this one :self.terrain.find("**/Blue") but what next?

Any help?

I’m not sure want you want.

since you have your nodepath, I suppose you just want to do

node.hide()

This node is collisionNode so it doesn’t have hide().
I want to collide to this node and after this node get disappeared.
So I want to have somekind of control over this node that it is in the egg file as a.
