In this chapter we will create a blood flow animation using particles and a curve guide.
We will have control over our particles, change their rotation, emission order, amount per instance object, and more. We will then introduce some plaque build up in the vein, and have the particles flow around it. There is another option for affecting particles with curves, with a force field and its shape set to curve, so we will start the video with an overview of some the differences between the two.
Hope it will be useful and see you in the next chapter!
