In particular, the case when the "instance_geometry" element has no "bind_material" sub-element. This is valid, according to the official collada 1.4.1 specification."
Add check in RigTransformSoftware if bones are null
Indent TimelineAnimationManager
Add check for NaN in UpdateCallback.cpp

Fix Computation of bounding box for RigGeometry
There is a small bug with your change and SubloadCallback, the texture object is destroy at each call of Texture2D::apply because the modified count is never updated when using SubloadCallback.
I have made a small fix to avoid that, see attachement."
From Robert Osfield, added an if (_image.valid()) before the getModified() that Fabien added to avoid problems when no _image is assigned but an subload callback is.
> loader to un-premultiply the alpha (now in the codebase).
Applying the code brightens the semi-transparent portion, but the black edges are still there (same on both osgviewer and FlightGear).
Therefore I believe that the alpha channel is completely ignored (on png, gif, tiff, etc...). I tweaked and tweaked and finally got a workaround.
Please commit the enclosed file to fix these issues.
My workaround is a bit tricky (and some lines are even weird for me), but it resolves the black edges.
These workarounds also work on GIF, TIFF, TGA, and PSD as long as I've tested so far.
Please read this for more info on this issue:

I'm very happy if some of you guys find a better means of solving the black edges.

"Here is our freshly baked 3DS reader/writer (named 'v0.5' to differentiate from previous one). Changes are against trunk rev. 10819.
Short changelog (from rev 10819):
- Added 3DS writer
- Sync'd with latest lib3DS
- Added options, especially "flattenMatrixTransforms" to get the "old" behaviour (else the reader correctly maps to OSG the transforms from the 3DS file).
What should be done:
- Check with pivot points, with and without "flattenMatrixTransforms" option.
- We ran tests on it, but we can never be 100% sure there is no bug. Testing from the community would of course be helpful."
