Website Update: What’s new on Sketchfab this week?

Back to overview

This week we’re releasing some behind the scenes improvements. We’re taking a first step towards future improvements, and have added support for Kerbal Space Program parts!

Kerbal Space Program support

We have also added KSP’s *.MU file format to our list of supported files to make uploading of parts easier. And yes, before you ask, we’d also love to support uploading *.craft files – we’re looking to see if that’s possible!

Website performance

We’re currently attacking performance on two fronts:

  1. Data compression: we’re doing a much better job at compressing any geometry data we’re sending your way now. This will be most obvious with large models of course. Can you tell the difference?

  2. Website performance: we have taken a first step towards making the overall website faster as well. With this week’s release we have laid the groundwork for optimizations that we’ll be working on over the next couple of months to make Sketchfab even more enjoyable to use. As such, you won’t be seeing an immediate speed upgrade this week, but we’ll be adding more and more improvements soon.

Like I said: stay tuned, we’ll be putting a lot of effort into this over the next few weeks.


  • You can now rename folders.

  • Inserting HTML snippets could sometimes break comments, we fixed that.
