I downloaded the 3D model and opened it in Blender. Then, as I usually do, I exported it for the ThreeJS scene (in GBL format). However, it, with the usual addition, as I did on other scenes with other 3d models, is not visible on the scene. Although I tried to scale the scene (zoom in, zoom out, change position).
If I use this resource (Model Editor), then it displays both the model and its animation.
I also added a cube and a sphere for testing. These two items appear on both my scene and that site’s scene.
As I understand it, perhaps there are some parameters that are difficult to guess that need to be changed. For example, I tried to change the size to 0.001 and to 0.5. The two items next to the main model that I added for testing are visible. But the model itself is not.
I also tried various options for exporting the model, with different parameters. This also didn’t work.
Model is here:
but I didn’t understand how to add the static folder there (so that the files from it are available in relative links)
