Sometimes, 3d models are hundreds of megabytes, even gigabytes. We now support many of those
Big files can be a pain in the neck, and that also goes for 3D files. But sometimes you have one, and sometimes you need to convert it.
With the recent release of Convert3D, you can now load and convert most formats well over a gigabyte, often more.
Since we do all our conversions in the browser for speed and privacy, we have to play within the rules of the browser. One such rule is that memory is a bit tightly managed. So to preserve memory, we don't show a preview if the model is larger than 100MB. We may change that limit in the future.
