Closed, ArchivedPublic


System Information

Blender Version
Broken: 2.10 19e627c
Worked: unknonw

Short description of error
Animation data for Material Alpha value is exported to DAE, but not imported by blender.

Exact steps for others to reproduce the error

  1. Start a new project (with cube).
  2. Switch to the cube material tab.
  3. Select "Transparency"
  4. Set Keyframe for "Alpha"
  5. Change Frame
  6. Set new value for "Transparency"
  7. Set new keyframe
  8. Export project to Collada-File (.dae) with default settings

(in the dae exported, the Alpha-Value-Animation is written)

  1. Start a new project and delete the automatically generated cube
  2. Import the dea-file created in step 8

--> No animation data is imported.

BTW: Thanks for the really great programm you created!

Gaia, I assign it to you, not sure whether you’d consider this as supported or unsupported part of Collada currently. If the later, feel free to mark as TODO and close.

We are sorry, but we currently have no maintainer for Collada area, and there is no point in keeping opened reports that no one will tackle any time soon.

We only intend to maintain basic support for SecondLife export, but it is very unlikely to get any more real work done here (even the OpenCollada library we use in Blender is a rather… quite project since some time now).

Bug tracker is for reports which are gonna to be tackled in a reasonable amount of time. Not sure how much Jesty is available for this, would be fine if he can tackle this but IMO it's more like a TODO
