Things that are fixed here:
|
|
|
|
----
|
|
|
|
3ds Max "file://" image URLs
|
|
|
|
Identifier: /COLLADA/asset/contributor/authoring_tool = "FBX COLLADA exporter"
|
|
|
|
Problem: /COLLADA/library_images/image/init_from = "file://" which crashes some versions of FCollada
|
|
|
|
Fix: Delete the whole library_images subtree, since we never use it anyway.
|
|
Then delete library_effects and library_materials too, to avoid broken references.
|
|

|
3ds Max broken material references
|
|
|
|
Identifier: /COLLADA/asset/contributor/authoring_tool = "FBX COLLADA exporter"
|
|
|
|
Problem: /COLLADA/library_visual_scenes/.../instance_material/@target sometimes
|
|
refers to non-existent material IDs.
|
|
|
|
Fix: Delete the whole bind_material subtree, since we never use it anyway.
