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.

Highlights of Build 35071
19 March 2010
- 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.
Sorted roughly by priority (as of build 35071):
- SourceForge bug #2974894, "Images not found during scene load" (Mac OS X).
- Fixed in build 35095. The test for an absolute path was incorrect on Mac OS X, such that images that weren't in the same directory as the scene file opened the search for image file dialog.
- SourceForge Bug #2889044, "disabled meshes are not excluded from export"
- Fix in process (builds 35099 and 35110).
- SourceForge Bug #2927090, "File loads with no polygons" (loads initial T-pose mesh, but still needs vertex deformers)
- SourceForge Bug #2909572, "Animation for some items not exported"
- SourceForge Bug #2889158, "baked textures not UV mapped properly"
- SourceForge Bug #2888147, "textures not exported properly"

- Triangulate scene saver option.
- 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.
- 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.
- Loading and saving skin controllers. (Test with Spore models.)
- Support for ZAE zip compression sub-format.
- Performance optimizations.
- Physics library.
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.
