Iterating with loop nodes

- A smart and simple way for us…to generate lots of geometry in PlantFactory…is to use a for loop.…This is just like in computer programming…when you have some command…that you want to repeat a certain number of times.…In this case we want to generate segments…that are connected to one another,…and we also want them to branch off…and do interesting things.…Before we get to that,…let's just change the material on this segment.…Select the segment and if you go to the Material tab,…you'll notice that it's blank, in this case,…because the geometry is taking over.…

When you do go to the Segment tab,…and the material is listed here.…We'll just make a new material from this pull down list.…New material, double click on the material swatch,…we'll rename it, we'll call it green cladode,…and then click on the Overall color down here…and give that kind of a dark green with a lot of saturation.…Click Okay.…Click Okay and we can unselect…and take a look at what simple green material looks like.…

Now we will create a loop…so we'll generate lots of these segments.…
