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 SP4 (build 34686) 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.

modo COLLADA 401 SP4 build 35392 released

Package Name: modo COLLADA 401 SP4 build 35392

Release: Build 35392

Release notes: modoCOLLADA_35392.pdf

Highlights of Build 35392

09 April 2010

  • Fixed SourceForge Bug #2889044, “Disabled meshes are not excluded from export”. Added the “Save Hidden Items” scene I/O preference option.
  • Fixed SourceForge Bug #2977343, “Triangles can’t export as triangles”. Added the “Save Triangles as Triangles” scene I/O preference option.
  • Fixed SourceForge Bug #2974893, “Images not found during scene load”. The test for an absolute path was incorrect on Mac OS X.
  • Fixed SourceForge Bug #2978904, “RGBA option for vertex color maps”. Instead of adding an RGBA option, the saver and loader now dynamically switch between the RGB and RGBA color map formats as needed.
  • Fixed SourceForge Bug #2977195, “Point-only geometry ignored”.

Previous Build 35071

19 March 2010

Changes in Build 35071

  • Improved transparency handling by adding support for the A_ONE and RGB_ZERO opaque modes for the transparent color element, and its interaction with the transparency element.
  • Fixed a bug which was preventing linkage of UV texcoord sets when the optional set attribute was missing. (Fixes linkage of the texcoord set for the “barrycuda” model from Spore.)
  • Fixed an inconsistency in how the default UV map name was set when a friendly name wasn’t available for polylist or triangle mesh geometries. In one case, it defaulted to the conventional “TEXn” naming scheme, and in the other case, it fell back to the texcoord source ID. Both geometry types now consistently use the texcoord source ID. (This was the second related bug that was preventing the “barrycuda” model from Spore from loading with its texcoord set already linked.)
  • Fixed a runtime error caused by an un-initialized result code for certain cases in the COLLADASceneLoader::LoadColors function.
  • Fixed SourceForge bug #2971652, “Model from 3D warehouse fails to load”. The loader was failing to find geometry normals, due to a bug in the VertexMapInputHub::GetNormalInputSourceID function that was introduced in build 34967.
  • Fixed SourceForge Bug #2940543, “Crash with area lights”.
  • Fixed a bug that was causing the offset attributes for geometry mesh inputs that followed a texcoord set (such as colors or weights) to incorrectly index into their index lists.

Previous Build 34967

12 March 2010

Changes in Build 34967

  • Loading and saving of vertex color maps and vertex weight maps, for all supported mesh geometries (polygon, polylist, triangle, and line).
  • Load and saving of asset metadata (author, copyright, keywords, revision, subject, and title), with per-scene overrides, which also persist in the native modo file format. (These settings now appear in the Properties panel when the scene item is selected in the Items list, as shown in the section, “Asset Descriptors”.)
  • Initial support for loading meshes via skin controllers in their initial T-pose. (TODO: Still needs vertex map deformer support.)
  • Fix for material transparency reversal during save and load.
  • Fix for loading and saving of custom vertex normal maps (previous vertex maps were saved with the default, automatically calculated geometric normals).
  • Fixed bug #20842, “Collada export incremental texture renaming”, by adding a map to associate material targets with their material names (when the user-friendly name is available). With this change, the material ID is only used when the name is not available.
