I created a model using Altizure, and I am wanting to upload it to Sketchfab. The file comes in a .Zip and a .kmz file. I have tried uploading both and keep getting an error 20, and one time I got an error 60. Is it possible to get this model uploading to sketchfab? It is a good quality model and should be able to covert over to the website. If not, is there anyway that I can transfer it to some other software that will convert it over to sketchfab? Thank you.
