I decided to try my hand at making some procedural materials, as a more or less complete newb.
So: I create an object. I add a material. Now I would like to go into the node editor to edit that material. This seems like it should be simple - it's so simple the documentation doesn't even mention how to do it - but ... how do I do it?
Here's what the documentation says:
Accessing the Node Editor
First lets enter the Node editor and make sure that the Node editor has the material node button (sphere icon) pressed, not the composite or texture node buttons.
That's right! The documentation on how to access the node editor simply tells me that I should access the node editor. I must be a complete idiot for not knowing how. (The link doesn't help, it just tells me how to use the node editor once I have it open.)
Here's what the relevant part of my screen looks like:
The button marked "use nodes" looks promising, but if I press it I just get this:
No nodes, just a different set of widgets.
I imagine there's probably some keyboard shortcut for this, and/or some icon in some random other part of the screen that looks like it couldn't possibly have anything to do with the node editor. Could someone tell me what it is?
