About SideFX Houdini

SideFX Houdini, developed by Side Effects Software Inc. since 1987, is the industry-standard procedural 3D software for visual effects, simulation, and dynamic animation in film and television. Houdini 20.5 represents the latest evolution of the platform, introducing Copernicus for GPU-accelerated 2D/3D compositing, enhanced MPM multiphysics solver for realistic simulations, and sophisticated character rigging through APEX Script interface. With its node-based procedural workflow, Houdini enables artists to create complex, reusable, and editable visual effects faster than traditional modeling approaches, making it the preferred choice for major studios creating blockbuster films and cutting-edge visual effects.

Frequently Asked Questions

What's the difference between Houdini Core and Houdini FX?

Houdini Core ($1995) includes modeling, animation, rigging, lighting, and rendering for modelers and animators. Houdini FX ($4495) adds complete simulation tools including Vellum, Pyro, FLIP fluids, and advanced dynamics for VFX artists.

Can I use Houdini on Linux?

Yes, Houdini 20.5 fully supports Linux including Ubuntu, CentOS, RHEL, and Debian. Performance is comparable to Windows with full GPU acceleration support for NVIDIA and AMD graphics cards.

Is there a free version of Houdini?

Yes, Houdini Apprentice is free for non-commercial use. Apprentice has output watermarks and render resolution limits but includes full features for learning. Houdini Indie ($299/year) is also available for independent artists.

What rendering engines does Houdini support?

Houdini includes Mantra (CPU) and Karma XPU (GPU). Third-party renderers supported include RenderMan, Arnold, V-Ray, RealFlow, and others through standard rendering interfaces.

How does Houdini integrate with other software?

Houdini exports and imports standard formats like USD, Alembic, and FBX for seamless pipeline integration. Houdini Engine allows embedding Houdini in Maya, Unreal Engine, and other applications.

What graphics card do I need for GPU acceleration?

NVIDIA Maxwell series or newer (GeForce RTX, Quadro RTX) with 12GB VRAM minimum, or AMD Radeon Pro with latest drivers. Karma XPU supports multiple NVIDIA GPUs for distributed rendering.
