Presentation of the Houdini course …based on theorical examples, and their application in a global scene Covering all major chapters Classic Modeling (Retopology | UVs) Fundamentals (Groups | Attributes | Instancing | HScript | VOP | Vex) Procedural Modeling RIG (Autorig | Manual | Skin | Muscles) Animation (Takes | Layers | Groups) CHOPs (Constraints | Sop level) Heightfields (Sculpt | Layers | COPs | Instancing) Volumes (VDB | SDF | Clouds …) Particles (Emission | Forces | Collisions | Groups | Advection) RBD (Fracture | Manual Constraints | RBD Tools | Bullet Solver | Attributes) Pyro (Emission | Combustion | Forces | Sparse Solver) Vellum (Cloth | Hair | Ballon | Struts | Fracture | Dynamic Constraints) Grooming (Guides | Attributes | Simulation | Render) FLIPs & Ocean Tool (Small & Large Scale | Viscosity | Whitewater | RBD Feedback) Rendering (Attributes | Material Builder | AOVs) Assets PDG (TOPs) Crowds (Agent | Locomotion | Footlock | Terrain Adaptation | Ragdoll) USD – Solaris (Layers | Instancing | Karma) On demand examples… In this course for newbies and mid-users, we start from the very basic Houdini handling, and we cover each chapter one by one, using newly learned technology to enhance the student’s main scene. The example above is one suggestion of the main scene.

First try on “Heightfield” module in Houdini. …with very quick and bad Photoshop compo sorry no time 😉 Main goal, more than testing the very great Houdini’s “Heightfield” tools, was to build a workflow based on Cops, so third-party renderers could easily read masks and textures generated by the Heightfield tools suite. https://vimeo.com/267026899 Terrain base Shape First starting with a lowres grid (100×100), for placing the global volumes, and tracing the river zone. First basic noise Painting of the river Smoothing and refine before carving Refining Upsampled (1000×1000) it to have the correct look and details for terrain filters like erode, noise and slump. applying large Worley noise using mask to merge with original noise, erode and distort on the second part carving river again slump near river fine-carving river Extracting Maps As the aim was to create a third-party render-friendly asset (thus I’m using Redshift), it had to be able to export “standard” type of data including maps, which are originaly based on native heightfield masks.To do this they had to be translated into Cops, which also permit more complex mask/textures generation. import legacy heightfield masks into Cop for creating complex texture masks visualizing masks with color pointclouds for vegetation Textures and Vegetation Using the maps from precedent Cop in Redshift shader nodes. import heightfield into Redshift adapted node importing embedded Cops and referencing maps using them in Redshift Shader’s blending Not that good at this time for very close shots, and water will be worked on next step… Textures and trees found on the internet.
Modeling for both HighRes and Realtime …from ZBrush to Houdini, and very soon Unreal Engine ZBrush Modeling Modeling and retopology with ZBrush. Modeling and apart export of specifics lowres parts. base modeling base modeling retopology thruster reactor turbine Houdini rigging Import of and assembly of ZBrush elements, UV layout and rigging, with the goal to conserve a very low but subdivide friendly geometry. The array meshe parts from ZBrush had to be remade in Houdini in order to be more easily rigged, and required to be all individuals (no instances) so they all have their own UVs (and specific textures) import and reassemble for very geometric parts UV layout defining of bevel edges bevel and subdivision test Hudini rigging for moveable parts final assembly export for texturing Substance Designer Creation of the metal panel’s procedural texture. creating tileable plates pattern extracting rivets zones creating rivets assembly parameters export and test render Substance Painter Classic work of texturing via Substance Painter. Use of instance layers for red color accross parts, and anchor Layer for scratches reacting to normal details layer.Maps exported in Unreal Engine 4 preset, so can be used in both HighEnd and Realtime Renderers. base pre-created metal plattes basic painting (red pain as an instance layer) basic scratches screen same for “turbines” and reactors Final Render Back to Houdini with Redhift (PBR worlflow). …with a tip to show Redshift textures in display. houdini testing and Redshift rendering test render test render test render
Technical Direction of a marvelous Video-Mapping Tool …the kind of toy I like ! For 6 months I have been in charge of the technical direction of a very new and advance tool, that we could describe as an all-in-one videoMapping truck, produced by the Athem compagny. It embed 6 Modulo Kinetic Servers, 4 Christie Boxer 4K30 video projectors, and Graphist toolset for responsivity and on-site performance. The result was so great that we rapidly made a second one ! Conception While the main structure conception was done before I joined the crew, I had in charge the design and installation of the main broadcast system. I choosed Modulo Kinetic for the broadcast embedded system, due to it’s capability to handle multiple synchronised players, and it’s massive realtime tweakability, allowing any kind of interactivity and on-site performance. first road test first road test an inside view during the assembly On-site Direction On-site I worked as video-projectors and Modulo Kinetic operator, and when those jobs were done I usually made an user-friendly interface, so it could be manageable by non-expert users (for shows during multiple days). The Grand Palais, Paris The Louvre, Paris Bibliotheque François Mitterrand, Paris Upgrades and Maintenance When not on-site, my job was to make the trucks always ready to go, and upgrade the system (like putting the Internet for remote control, making the two trucks synchronised, etc) I’d like to greatfully thank the Athem compagny for putting trust in me and together making this incredible project happen.
Simple research with Houdini, strokes and Redshift …yep, I’m testing Redshift That’s all folks !
