HTB (Houdini to Blender Exporter) is a tool designed to import attributes from Houdini into Blender Geometry Nodes in an easy, quick, and efficient manner. It works with regular geometry and point clouds, but not volumes.

Key features:

  • Import Houdini Attributes: Seamlessly import attributes from Houdini into Blender Geometry Nodes.
  • Supported Attribute Types: Export integer, float, vector, color, and quaternion point attributes.
  • Efficient Data Handling: Utilizes vertex animation textures, saving attributes in an EXR image where each pixel contains data values of certain points.
  • High-Resolution Attribute Storage: Handles high-resolution data efficiently, for example, a vector attribute for a 10 million point mesh would be stored in an image around 1000 x 1000 pixels, and a float attribute in an image around 500 x 500 pixels.
