Rebelway - Intro in FX - Week 2

General / 20 March 2018

So the second week of the Rebelway course started out a bit rough, seeing it focused on VEX coding and some basic vector Math.

Two things that aren't my strong point, but going over them and reading up on the basis behind it helps me out quite a bit and in the end, I do understand the inner workings now.

The week was focused on a couple techniques, the first one using a geo and emitting and directing the emissions with curves.
And even more handy, using noise based effects for the emission.




The second effect was focussed on the shortest path function, which is a great handy tool to create organic growth curves over a geometry. The example showed it in a 2D version and I would love to use it on a 3D object for a nerve system type of growth.


The portal FX I haven't had a chance to really play with yet besides the classes, so this is something I will do in this week, seeing the classes build upon the example and add some smoke FX to it.


Then we got working on an effect that was based around a meteor-like impact and the layered effects coming from that.

My setup is quite simple, using a pop emitter to emit magical drops that on impact create a collision and from that spawn clones with randomized values to emit more particles. Underneath that there is also the growth pattern to releasing another layer of FX.


Rebelway - Intro in FX - Week 1

General / 12 March 2018

So last week I started this course: rebelway.net/intro_to_houdini_for_fx taught by Saber Jlassi.

In the beginning, I was kinda on the fence if the live element would be worth it and if the level wouldn't be to low. And after a week already I can conclude that it is.

There's so much worth in having somebody explain something as complicated as Houdini in a way that you can grasp it. Having done a shit ton of tutorials, also in Houdini, this is just on another level, that combined with the live feedback sessions and the discord for questions. 

If you are looking to get into Houdini, and you have an advanced level in other 3D programs, this would be my recommendation.


The following tryouts are based on some macro shots of eyes that I found here: behance.net/Your-beautiful-eyes

Here a small test I made after the classes with one of Saber's setups.

And an animated version, all setup without any simulation, just scatter points being animated by VOP noises.
