Actual Behavior

When uploading mesh with custom LODs, containing an object with the same object name in two LODs, the following error message appears: "Error: Material of model is not a subset of reference model." (It makes no difference whether there are materials defined or not)

Steps to Reproduce

test.dae contains two objects: Cube3 and Sphere3.
test_LOD2.dae contains two objects: Cube3 and Sphere2.
When uploading this, the error message is thrown.

Expected Behavior

It should be able to handle such LODs with same object names.

Other information

Oddity 1:
When both files contain only Cube3, there is no error message.

Oddity 2:
According to the SecondLife.log, all objects within the LODs get renamed to have unique names, as soon the .dae-files got selected from the upload window.

Background:
When modeling complex buildings with several dozen of objects, it is very helpful to organize them with Layers or Groups (for example in Blender). One can assign an object to multiple Layers/Groups, if it is used unchanged in all of them. This reduces the possibility of mistakes and the working time drastically. But as a result after exporting, one has some object names in multiple use.

Most of my mesh project files (+100) are broken now. Of course I could work-around by creating copies with unique names of all those objects used for multiple LODs, but that would cause so much work, that it makes no sense.
