- [Narrator] All right, so we've created our nice smooth trail geometry from our cash particle sequence and now we're just gonna do a few more things just to prep our geometry. We have to color it and to do everything we need to do to get it ready to render. So what we're gonna do, is first I'm gonna make a polyframe and a polyframe is gonna allow us to generate normals and up vectors so let's turn off, where it says normal name and I actually want that off, and I wanna turn on tangents and bitangents. Now the tangent being N and the bitangent be up. So now if we turn on normals in the viewport you can see that actually generates normals down the length of the geometry. If I go to my visualizers and we turn on our up visualizer that we created before, you can see that now it's actually creating up vectors that's technically the bitangent of the geometry. But you can think that's just sort of perpendicular to those normals. So this is just a nice way to create some good attributes that…
