Please note that this is an animation of the model, not the model itself. In order to upload these high-resolution, animated, dense models, more SketchFab space is needed. This means a Pro account, which is £180/year. Before you say, wait...why don't we just use Unity? Unity Pro is $2,310. The cheapest route is passive animation. So this may make our decision between passive animation or a lightly interactive offering for us.
