%%%I get weird strange deformation errors in the mesh when I import this animated avatar (which was exported from 3Ds max using OpenCOLLADA 1.25) into 2.56a:

http://www.katajs.com/res/exported-max-opencollada125.zip

Blend file is here:

http://www.katajs.com/res/avatar.blend

Looked good in t-pose when first imported but as soon as I play the animation I get the weird deformations.

This is the file re-exported to COLLADA just as an fyi:

http://www.katajs.com/res/re-exported-blender256a.zip

Additional fyi the model is CC BY licensed so if you need an animated model for demo purposes feel free to use it.%%%

%%%Nice test for nathan!%%%

%%%Nice test for nathan!%%%

%%%Got to thinking if it was related to animations so I found the .blend from http://www.blendswap.com/3D-models/vehicles/buggy/

Direct link to file here: http://www.katajs.com/res/buggy.blend

I exported this to COLLADA and got: http://www.katajs.com/res/buggy2.dae and when I reimported this file the geometry also looked whacky.

I did try and export to 3DS and reimport and the geometry looked fine.

This may be a separate issue but I thought I would leave it here as a comment first.

Ps forgot to leave my hardware stats:

Mac OS X v10.6.6 v NVIDIA GeForce 9400M
Model Name: MacBook Pro

Model Identifier:	MacBookPro5,5
Processor Name:	Intel Core 2 Duo
Processor Speed:	2.26 GHz

%%%I checked the buggy file from blendswap. This type of armature use is not yet supported, as per http://wiki.blender.org/index.php/Dev:2.5/Source/Architecture/COLLADA#Supported_COLLADA_features only single skin controller on one object works. Code to support the type as in the buggy has to be written still.

Marking as todo.%%%

%%%Nathan,

I inspected the file. It contains only one skin controller. To me, it doesn't contain anything we cannot support currently.

I get "cannot find bone" messages on the console. The reason seems to me either malformed DAE or import bug - needs investigation.

I'm reopening this bug because it is an existing feature bug.

The file looks like a good test case for future. :)%%%

%%%Collada bugs are not being handled well so far,

for this reason they are all being set as 'TODO' and linked from our wiki page.

http://wiki.blender.org/index.php/Dev:2.5/Source/Development/Todo/Import_Export#OpenCollada

This tracker item can still be updated with useful info and closed (removed from the page above) when fixed.%%%
