Blender files and Library linking

  • Mixing "direct" and "indirect" data not well supported report

OpenCollada

Moving opencollada bugs to TODO has been done because our capacity for actually working on this module is very limited. this does not mean that collada has been forgotten. It is maintained but it progresses too slow for the Blender release cycles.

Plans

Short term goals (Blender 2.68)

  • Rework the Materials&Light section
  • Organize module testing. Please feel free to provide test cases and results on this page
    • COLLADA Conformance Test Suite has now basic Blender support integrated. We can now create a batch of files that we can drop into the test sets directory to create an easy way to test for regression and fixes.

Long term goals

  • Make Blender Collada feature complete
  • Improve interoperability with other 3D tools
  • Rewrite the Collada module for easier maintenance

Application Support

Here we collect which Apps Work, Which have issues. Currently the list is in relation to Blender revision 56419 (just before Blender 2.67 release)

Collada compatibility

Target System Static Meshes Armatures Animation Comment
Blender OK Error ? Needs to be fixed
Second Life OK OK n.a. in depth tests in progress
Maya 2012 OK partially OK ? Waiting for response from Tester

Tracker Reports

Here we collect the list of still unresolved reports which have been moved to the TODO list for various reasons.

This is the color code used in the following lists:

  • not colorised: The report has not yet been checked.
  • This report needs more information
  • This report is most probably resolved
  • This report is partialy resolved
  • This report definitely needs to be resolved

Reports which have been verified by the reporter as "resolved", will be removed from this list.
