Hello,
I've never exported a file of this type and have no idea how to do it. I tried a few times but only received an error 13. Here's a link to one that uploaded but I cannot view it in my browser ( https://sketchfab.com/3d-models/sculpting-basics-d6335562f8964715a41f06a2039f5da5 ). Any help would be appreciated. Here's a screenshot of my shark though...
