Exported Collada file crashes Blender and Sketchup

Exported Collada file crashes Blender and Sketchup

Problem can be seen even with example in documentation: https://threejs.org/examples/?q=collada#misc_exporter_collada

I tried several different 3d programs and Modo, Max, Maya and Archicad handles exported file just fine, Blender and Sketchup crashes and SweetHome3d just refuses to import the model. I worked around it by adding profile="" to technique in extra in generated file and Blender and Sketchup imports it fine now.

        <extra>
          <technique>
            <double_sided sid="double_sided" type="int">1</double_sided>
          </technique>
        </extra>

I don’t know if that’s not breaking something elsewhere, but from what I’ve seen it’s fine. SweetHome3d still doesn’t import it, but I don’t know how to debug it as nothing comes up in console.

@marekjedrzejewski Can SweetHome3d load the file if the profile field is set to a non-empty string?

Unfortunately not, I think it’s not connected to technique tag. I also tried to remove whole extra before, which loaded fine in blender and sketchup too, but sweethome3d also didn’t work with this. I will try with some really simple models tommorow, cause collada exported from blender works. If I’ll use something simple, then it would be easy to see differences berween the one from blender and one from threejs.

Maybe we should just export “THREEJS”?

As far as I understand the spec, the value can be arbitrary. So THREEJS sounds good to me.
