exported collada texture mesh not loading

[Sayeed khan]

i have generated a 3d model of a building and exported the texture mesh in collada format , the dae and png ("img1" - attached file )both files were loading on the web viewer
later --
when i apply certain mesh filters like hole-filling etc and regenerate the texture mesh from the cloned previous mesh and export it in collada format the dae and png ("img2 - attached file )both files NOT were loading on the web viewer
i have noticed a difference in the png files of both the exported texture mesh
the problem is when i get uv mapping of the mesh like ("img1-uv"-attached file) the model is loading on the web
and when i get uv mapping of the mesh like ("img2-uv"-attached file )the model is not loading on the web
is there any setting to set or to make sure any particular limit in properties , so that i get the texture mesh like ("img1" - attached file )

Hi -

The layout of the UV islands should not have an impact on compatibility, but naming conventions and other things might! It's also a bit strange that the UV map looks like that - Which web viewer are you using and is the 3D model being imported/exported out of any other 3D software?

Can you please share the two models (working and not working) so we can have a look and see if there are any obvious reasons this might be happening? You can send file download links to support@3dflow.net
