Houdini Solver for Frame Events Tracking

Say goodbye to tedious manual keyframing or guessing event timings.

StartFrame Solver for Houdini is a powerful procedural tool that automatically detects and computes start frames based on custom boolean conditions. Ideal for FX artists, technical directors, and animators, this tool helps you trigger events, optimize simulation caches, synchronize animations, and automate complex Houdini setups with precision. Take full control of your simulations and save hours of manual work with StartFrame Solver!

Detect Event Triggers

• Capture the exact frame when a point or primitive attribute reaches a condition.
• Detect when a point or primitive enters a group.

Built-in Visualizers

Instantly check computed attributes directly in your viewport for easy debugging and setup.

🧠 Use Cases

• Precise Event Syncing
  • Align simulations, FX, or animations perfectly with events or sound beats.
• Simulation Optimization
  • Trim heavy caches by eliminating unnecessary pre-roll frames.
• Automation in Complex Setups
  • Automate triggers across large, dynamic systems.
• Documentation & Debugging
  • Visualize and export start frames for clearer simulation behavior tracking.
