Heightfield advection is a powerful technique in Houdini for simulating complex terrain evolution and fluid-like effects.

Intrinsic UVs in Houdini are a powerful way to access geometric properties without extra attributes. Depending on the primitive type, they are interpreted differently.

Houdini Tokyo HIVE video is live:

I wanted to share a quick visual comparison between the SideFX recording of my Houdini HIVE Tokyo 2025 session “Adaptive Fracture Synthesis and Propagation in VEX using OpenSubdiv Limit Surface Derivatives” and my own local QHD capture.

The SideFX version is completely fine for watching the presentation, but my recording was captured directly from my display source with no compression loss, so it preserves a lot more clarity across the entire presentation. This includes all geometry details, colors, UI elements, and text. This is one of the main reasons I am preparing my own edited cuts.

The attached images show the difference between the two versions.

The full END-JPN cut will be posted next, followed later by the English-only version. These edited cuts will be available exclusively to paid members on Patreon [www.patreon.com].

Pragmatic VEX: Volume 1: Canonical Version Update

Over the past 3 months, I’ve completely rebuilt the course.

Every video has been re-edited for better flow, pacing, and clarity.
Explanations have been refined, key sections restructured, and the overall learning experience has been significantly improved.

This is now the canonical version of the course.
It replaces the previous version.

• All lessons reworked for tighter structure and better comprehension
• Redesigned concept visuals and supporting material for clearer presentation
• New annotations to reinforce important ideas
• Help pages redesigned with proper styling instead of raw captures
• Updated to align with current Houdini workflows

The goal was to reduce friction and improve understanding while keeping the full technical depth intact.

If you already own the course, this update is available to you.
If you were considering it before, this is the right time to start.

More content is already in progress and will be released this year.
