Mantra PBR Hair

A render test of a custom hair shader for mantra. Added a more accurate Marschner TRT, and seperated the reflect into more logical reflect and coat components. Also added some minor randomness to the shift on each strand. Added Volume colour scattering in an attempt to create a volumetric feel to geometry hair.

This paper is great inspiration: eugenedeon.com/project/importance-sampling-for-physically-based-hair-fiber-models/

Thanks to Corbin Mayne vimeo.com/user3437874 for his awesome work on the guides, and the volume colouring.

As I haven't implemented frenel, the system is not yet fully Physically Based. Hopefully I will share an update with this figured out in the near future

Houdini Tutorial - Create Wetmaps Using CHOPS

Hey guys,

Recently did a river sim where and build a wetmap tool for that, and thought it would be make for a interesting subject for a tutorial.
Video is a bit longer then my usual stuff but I think there should be some useful tips and tricks in there.
Let me know if you have any questions.

Here is the attribute blending asset that I'm using in the tutorial, it's using HDALC, so can only be opened in apprentice and indie:

Demoreel breakdown:

X-Men: Apocalpyse
Cyclops eye beams
Procedural volumetric noise interference patterns implemented with Houdini VBDs and a fairly involved compositing setup (Nuke) to develop this look.
Tree fire implemented with Houdini 15 pyro.
Gods of Egypt
Distributed pyroclastic smoke simulations on Apophis. Creature was counter animated so it's head sat at origin in an axis aligned wind tunnel.
Pompeii (Mr X)
2013 FX TD - Houdini
Pyroclastic smoke simulations. Built a library of custom volumetric geometry sequences with proxy low res components that allowed artistic layout of pyroclastic smoke plumes. Custom volumetric shaders (Mantra) to effect the pyroclastic look and an animated displacement shader for the vortex effect. Smoke assets were rolled out to other members of the FX team.
Gravity (Rising Sun Pictures)
2012 FX TD - Houdini
Kessler field. Background debris burning up in atmosphere. Procedural Houdini FX.
Harry Potter 7 part 1 (Rising Sun Pictures)
2010 FX TD - Houdini
Worked on bespoke animation and simulations for the Horcrux sequence as part of the FX team. Meat, slime, ink & leaf effects.
Journey 2: The Mysterious Island (Rising Sun Pictures)
2011 FX TD - Houdini
Developed and ran bespoke plant simulations to interact with animated characters (collision and wind). Bespoke plant debris and leaf simulations. Procedural layout, lighting and rendering of valley of flowers.

Houdini Quicktip - Adding Alpha Maps To Principled Shader

NOW IN GLORIOUS 4K

Hey guys,
So just a short one this time.
Nothing too complicated, but something that caused me issues when I was trying to do something like this a while ago.

I thought it was weird that the new principled shader didn't have settings for alpha build in by default even though it does pick up on it in the openGL view, so I thought i'd go ahead and record a little tutorial on how to add that that. I'm showing how to make a system that let's you either use image alpha, or a seperate alpha map. Let me know if you have any questions.
Here is the HIP file:

Cheers!

Multiverse for Houdini

In this video you can see a simple example of storing multiple "revisions" of work in the very same Alembic file. This is achieved using the Multiverse 'Git' back-end. You can also see that things work as expected when rendering with Mantra (with motion blur) and that you can swap revisions pretty much interactively while working in Houdini.

Enter the Multiverse: multi-verse.io
