High precision positions / transform (64-bit) for giant scenes
Some use-cases require extreme value ranges when it comes to node positions/transforms (think globe-, or universe-scale scenes)
While glTF's JSON is capable of representing high-range values in text form, Unity's transform system works with/is limited to 32-bit positions. This limitation might be solved natively someday or with a custom high-precision hierarchy-transform, but as long as this is not solved this feature request stays on hold.
For reference: conversation started in #175
The High-Precision Framework has been released recently. Investigation is outstanding.
