A recent change has broken our exporting tool (Earth Volumetric Studio).
It appears you dropped one of the environments - the "studio_02" environment (UUID "efd4ef0fc18a4ec0a1313d782fade965" ) is no longer available on new models.
Our exporter automatically set this environment, as it was the only one that looked reasonable with our scientific models. With this environment unavailable, the API returns an error when existing users try to export to Sketchfab.
Can you please make this environment available again? It looks far superior to the main "studio" environment (the best of the current list) with our style of models, and is better than all of the other models.
In addition, it would be nice if the API wasn't "all or nothing" - right now, since the environment tag in the JSON fails, nothing is updated. If it would do the other updates except the one that isn't valid now, it would at least get people most of the way there. Without this, the model that gets uploaded looks very poor by default.
