Converting points to instance channels
- [Instructor] Now that we've built all of our points that we actually want instance geometry to, now we're going to convert these points into channel data that the instancer is going to what to use to instance all the geometry. So what we're going to use for this is a sop to chop node. So what I'm going to do here is type tab, I'm going to type chop and type S-O-P and we'll get a sop to node. Alright, and now under sop here, we're going to type points. Alrighty, so now you can see what we actually have is channels for tx, ty and tz. If we middle mouse click, you see that we have 10 points, zero to nine, one to 10, it's basically taken each of the 10 points and at every sample along the channel it's put its x, y and z value. And now we don't just want the position, we also want the normals. So under attribute scope, you see here where it's taken the p, position data, and it's renaming it out into tx, ty and tz channels. I'm just going to add the normals into the mix here too. So after…
