A complete reimagining of the 2D compositing and texturing context, driven by modern GPU acceleration.

A dedicated SOP to convert car geometry into a dynamic rig with suspension and motor constraints. SideFX Houdini 20.5.278

Now features non-destructive animation layers and improved rigging tools, making it easier to keyframe character motion and manage complex rigs. Vulkan Viewport: A complete reimagining of the 2D compositing and

Improved update speeds when cooking complex layer operations in deep scene hierarchies. Vulkan Viewport: Improved update speeds when cooking complex

New workflows enable artists to work with non-destructive animation layers, making it easier to tweak motion capture or keyframed data without destroying the underlying rig or animation.

Vector Expression (VEX) code executes faster across high-core-count processors (such as AMD Threadripper and Intel Xeon).

: Features an advanced MPM solver for highly complex simulations. Masterclasses released with this build focus on production-ready solutions for granular materials and customized setups. Startup Performance : The initial startup time for build 278 is approximately 1:00 to 1:15 minutes
