Course Overview

Class Description:

This recorded course will walk you through generating point normal data by way of advection to produce interesting flowing movement fx for use in design work. Multiple setups will be explored to offer different approaches in producing this effect as well as harnessing the power of Redshift3D instancing.

Learning Outcomes:

Students should leave with a better understanding of advection techniques, generating and extracting point attribute data, influencing flow directions, volume and particle simulating, as well as Redshift3D proxy export and instancing.

“Don’t miss out! These lessons are so incredibly deep and if you sign up for a live class, you get to participate and ask questions.”

Lukasz Pason

“Thanks again for sharing so much amazing info to us all, definitely will watch through the videos bit by bit before asking any questions you already have answered : )”

Theodore Daley

“Picked this course up too!! Advection is my favorite. @David Torno | Educator I am going through the velocity course and I really enjoy your method of teaching. I am finding your lessons easy to follow and I like how you put the other students questions in from the original class.”
