Adding to the list of products

modo 401 is a Digital Content Creation tool from Luxology. It has COLLADA support through the modo COLLADA plug-in.


The modo COLLADA plug-in requires modo 401 SP2 (build 32834) or later, running on either Mac OS X (Intel or PowerPC) or Windows (32-bit or 64-bit).


The modo COLLADA exporter can output geometry with normals and multiple UV texture coordinate sets, lights, cameras, materials, effects, and transform animations, all using a “common” technique that is compatible with a wide variety of third-party tools.

The exporter can also output a modo401 profile technique, that provides a human-readable form of many of modo’s items and their internal channels and animation envelopes. Users familiar with the COLLADA file format can also directly edit the exported files using a plain text or XML editing tool.

For additional compatibility with third-party tools, the exporter can also output profiles for a number of third-party DCC tools, such as Autodesk Maya and 3ds Max, that describe a number of elements that are not part of the standard COLLADA specification.

Highlights of Build 33836

11 December 2009

  • Node elements with multiple instance_geometry elements (SketchUp).
  • Mixed geometry mesh types per node during scene load (SketchUp).
  • Save and load pivot transforms and their inverses.
  • Scene load of transform for straw in styrofoam cup sample.
  • Fixes for transform sequence read/write order.
  • Recognition of post- vs standard-rotate transforms.

Known Issues

Sorted roughly by priority (as of build 33836):

  • Load and save vertex weight maps.
    • Completed for polylist mesh geometries (34789, 34800, 34811).
    • In process for triangles and polygons.
  • Load and save vertex color maps.
    • Completed for polylist mesh geometries (34833, 34832, 34826).
  • Load and save custom vertex normals (currently always saving geometric normals).
    • Fixed as of build 34598.
  • Polygons elements with holes (SketchUp).
    • Single inner loops in process for future build (33018, 33092, 33100).
  • Polygons and polylist elements with initial vertices at concave locations.
    • Fix in process for future build (33092).
  • Hole conversion in polygons elements with variable maximum index offsets (SketchUp).
    • Fix in process for future build (33141).
  • Deal with transform sequences for ambient light (create a locator).
  • PolyRender channel I/O.
  • Import up-axis.
  • Import units.
  • Render Camera target for Shade Tree Render item.
  • Add user value to export cfg for modo COLLADA build number in asset tag.
  • Polygon "face" or "subdiv" types: polylist/triangle extra param to note all polys of same type.
  • Item tags.
  • Add "item_name" to modo profile, for unfiltered name I/O.
  • Profile defs should sit in separate .h and .cpp files for each profile.
  • Use package API for light target channels (cameras already enabled for modo 401 SP2).
  • User channel saving and loading. (Needs more user channel APIs?)
  • Group list saving and loading. (Needs packages API?)
  • modo profile sub-type for locator vs group locator.
  • Fix distant relative image file path I/O.
  • Observe double-sided option in Google Earth/Sketchup profile.
  • If all transform axis keyframes have values at common times across all axes, then output scale, rotate, and translate animation channel elements as triplets instead of per-axis values.
  • Handle combined-triplet channel transforms on import as well.
  • Matrix animation subscript indexing (see sample 3ds Max files)
  • Profile params for rotate pivot and pivot compensation transform types.
  • Vertex color maps.
  • Resolve relative inter-file URLs in instance nodes during a scene load.
  • Polygon part tags.
  • Arbitrary polygon tags.
  • Fix remaining usages of "io" class variable.
  • Full shader tree I/O for materials.
  • Need full envelope I/O for render, materials, cameras, lights, and meshes.
  • Keyframe behavior mode.
  • Morph sets.
  • Loading and saving skin controllers. (Test with Spore models.)
  • Support for ZAE zip compression sub-format.

Previous Build 32654

31 August 2009

Changes in Build 32654

  • Valid scene file saved for scenes that only have ambient light.
  • Search more than one technique profile within a single extra element.

Previous Build 32619

28 August 2009

Changes in Build 32619

  • Recognize multiple instance nodes pointing at same node, and convert to modo instance.
  • Export geometry instances during scene save.
  • Filter out scale transforms for cameras during scene load.
  • Allow animation envelopes with missing interpolation inputs.
  • Better handling for isolated or post-rotate transform sequences.
  • Load polylines defined by the <lines> element.
  • Defer to global asset up-axis when visual scene does not have asset of its own.
