Hi, I'm trying to convert from the exported file in Sweet Home (obj) to Collada file .dae , but in process I've founded some problems:

Using this online tool , I upoload both .obj and .mtl files, and the .dae file is generated but without color.

Using meshlab, he gives the follow error:
Error encountered while loading file:
habitacion.obj
Error details: Identical vertex indices found in the same faces -- faces ignored

Then the obj is loaded, but when I try to export as .dae then the color is lost.

Using Maya, he gives the follor error:
Error: line 0: OBJ file line 616: index out of range for face creation.
Error: line 0: Error reading file.

and stops the import.

can somebody help me with this problem? the file is in this link
