The SideFX team launched a new version of Houdini 17.5 in Montreal, Canada. Houdini 17.5 is an important release that includes many key features. The H17.5 version code is PDG (Procedural Dependency Graph). This new technology is available in the upcoming Houdini 17.5 as a new Houdini operational context (called TOPs, Task Operator) and a standalone application called PilotPDG. Whether you're a movie VFX artist, a game developer or a business studio, Houdini 17.5 brings you new enhancements to meet your most demanding production needs. In addition, Houdini 17.5 has a variety of feature enhancements that you can learn about H17.5 new feature videos and release demo videos.In addition, there are many other improvements in 17.5, including a large upgrade of the view display (GPU accelerated real-time display Volume/Fireworks, standard material preview view and rendering height consistent), and special effects simulation part upgrade (drawing directly in view) RBD constraints, Vellum support different points for each Friction, etc.), upgrade of the modeling part (Measure measurement node 2.0, Terrarian terrain Erosion function speed increase of 70%, terrain support Alpha Cutouts / floating islands become extremely simple Wait). Vellum also acquired a new "fiber" constraint that functions like an internal bracket in an object, determining how it deforms. The orientation of the fibers can be manually adjusted using a modified version of Houdini's existing hair grooming toolset. Other changes to the simulation toolset include a new set of interactive RBD constraints that allow users to manipulate dynamic simulations directly in the viewport without having to edit parameter values. New gpu-based smoke shader, improved Principled shaderHoudini 17.5 also improved the display of volume effects in the window. The update introduces a new gpu-accelerated smoke shader that is "three times faster" than the previous shading system when using regional light sources. The new shader should also provide a more accurate preview of the interaction between scene lighting and smoke, including support for shadows and spotlights. Workflow: Override key SOPS, new multi-output display optionsWorkflow changes include "rewriting" of Measure SOP, adding options for calculating surface curvature and gradient as well as area or volume. Values can be visually displayed through viewport color coding, including built-in histogram display. Below is the conference video.
