Here are all updates, patches, bug fixes, and build info.

1.1.132 (Beta)

• “Particle” is now the default white water source mode.
• All particle to grid operations can use the new weighted mode instead of just velocity.
• Project non divergent’s surface SDF now exposes a radius option. Increasing this can make the fluid-voxel occupancy more accurate and results in less volume loss especially with low target particle count simulations.
• Project non divergent’s collision pre-conditioner has been massively simplified and results in more accurate interactions with animated colliders.
• Collider SDF’s values now affect project non divergent directly resulting in smoother, less stepy, collision-fluid surfaces.
• New density projection particle separation force. This separates particles without affecting velocities. It causes far fewer “fireflies” compared to the pressure force. This is the new default but pressure is still available.
• Fixed a bug with the point rasterize node that caused it to fail when trying to create it from the TAB menu.
• Multi-threading safety improvements for license operations.
• Fixed the profiler UIs in Houdini 22.
• Supports Houdini 20.5.684, 21.0.671, 21.0.729, 21.0.792, 22.0.429, 22.0.459, & 22.0.466 on Windows, macOS, & Linux.
• Cuda Version 12.2, Linux Driver 525.60.13+, Windows Driver 525.41+
• Released 23 October 2026, expires on 23 November 2026
• Download 1.1.132

1.1.118 (Beta)

• Adding a weighted particle velocity mode to particle to grid sampling. This makes velocity transfers more accurate.
• Added a new SDF surface creation algorithm that is 8x faster than the existing algorithm.
• Added SDF based project non divergent that makes particle surfaces more accurate. This is off by default but can be enabled under Advanced > Project Non Divergent.
