Here are all updates, patches, bug fixes, and build info.
1.0.169 (Beta)
- Added drag & speed limit forces.
- You can now source into particle attributes such as velocity, temperature, color, and viscosity with a VDB or source shape. The field source parameters have been updated to have either a (Particle) or (Field) suffix so you know if these settings are affecting particle attributes or fields. Custom sources also support this new ability.
- The output sdf & gradient fields have been renamed to “Collision Surface” & “Collision Gradient” to make it clear it is not the fluid surface. There is now also an option for fluid surface to be output but it is not yet implemented.
- Supports Houdini 20.0.896, 20.5.684, 21.0.512, 21.0.559, & 21.0.596 on Windows, macOS, & Linux.
- Cuda Version 12.2, Linux Driver 525.60.13+, Windows Driver 525.41+
- Released 05 February 2026, expires on 05 March 2026
- Download 1.0.169
1.0.166 (Beta)
- You can now diffuse and dissipate the color and temperature particle attributes. Pay special attention to temperature diffusion’s “Air Conductivity” parameter. This lets you control how much temperature is lost / gained through the surrounding air and colliders.
- You can use the viscosity or temperature particle attributes to drive viscosity. Temperature is inverted so low temperature values have high viscosity and high temperature values have low viscosity.
- You can now source collision temperature. Good for melting or freezing liquids when using viscosity + temperature + temperature diffusion.
- Fixed a bug where Houdini would crash if you re-initialized with no particles in your sim.
- Supports Houdini 20.0.896, 20.5.684, 21.0.512, 21.0.559, & 21.0.596 on Windows, macOS, & Linux.
