Switch to "use nodes" option

Hi,

In Blender there are some points, e.g. the “Surface” of “World” properties where the default is “Use Nodes”. Clicking on this gives you another set of buttons where you can set the options.

Now speficially for these Surface settings I want to start using the Nodes Editor again as it has functions that I need that are not available in this set of properties (I have to move it around a bit as the background is in the wrong direction).

Now how to get back to the “Use Nodes” so I can start using the Nodes Editor to set up my background texture? (this I expect to be a simple switch but somehow I just can’t find it by searching on Google and this forum).

for cycles
on bottom header you need to change from material to world nodes!

happy bl
