System Information
Windows 10, GTX970

Blender Version
Broken: 2.78c

Short description of error
Collada exporter assigns the same texture to all objects (with the same material) after export, even though each object has a separate texture assigned to its mesh surface and uv map, and everything is displayed correctly in the Blender textured viewport.
This bug disables to export larger scenes including baked textures, where multiple objects use the same material (e.g the same stone wall, etc).

Exact steps for others to reproduce the error

Multiple objects in the scene (same material used).
Each object has a separate AO texture assigned to its mesh surface uv map. Blender textured viewport displays it correctly as expected.
Collada Export (Export textures assigned to the object UV maps is enabled)
Problem: After Collada export, all objects has the same texture assigned to it surface.

Finally, I've created my own python based Collada exporter that fixes both issues https:*developer.blender.org/T51288 and https:*developer.blender.org/T51259

It enables me to export static mesh objects from Blender including all baked textures assigned to the active UV layers, exactly how they are visible in Blender textured viewport. And then, I can upload my build directly to Second Life without the need to apply textures manually, which is a nice time saver. Only drawback is the need for pycollada module that is not a part of official Blender, so must be installed into Blender's folder (eg. Blender/2.78/scripts/modules)

I put my script here: https://github.com/meshlogic/blender-addons/tree/master/collada-exporter-sl
