access queue tag from the editor

Is there a way to set the queue number from the editor?

I have a model made of different meshes imported from max and made into a prefab. I use transparent/diffuse shader for all of them but the order they are drawn is wrong. So I just want to indicate which is drawn first etc. with out having a separate shader for all the components.

Right now, no, your only option is to write different shaders.

In some future version we’ll add render queue override per material. So you could have different materials, all using the same shader, and override the queue in them.
