Wrong transformation? #13

Closed laraduarte closed 1 year ago

laraduarte commented 1 year ago

Hi,

I'm having issues rendering a model after exporting IFC file to 3dtiles. In the Cesium the tileset is correct.

The issue seems to be when I export by type instead of by group but then I have no colours on the model.

What can I do to fix this?

Hi Lara,

What application are you referring to when you say you export by group or type?

I see.

Please understand I cannot give free consultancy for a product that competes with mine.

Sincerely,

Hello again,

Sure I'm not asking you to do it, just give awareness that models like the one I attached (zip file) do not load properly with your plugin :)

If this is something you want to investigate or not it's up to you :)

The problem is perhaps with the gltf decoder. I use the gltf decoder from threejs while cesium uses their own.

However, threejs might argue the problem is with the tiles themselves. To fix this you'd need to extract the gltf from a tile and look inside to see what py3dtilers produces.
