I think that ISO8601 is used so ubiquitously and is so well supported that it's justifiable to use it as a baseline. It's the "least ambiguous and most agreed-upon" way...

I think that this is already _somewhat_ anticipated in the thoughts from https://github.com/CesiumGS/3d-tiles/issues/102#issuecomment-3307045781 , as part of one aspect that I consider to be important: There has to be "top-level"...

Scio me nihil scire. That said: While certainly interesting (for nerds like me), I don't see how this is applicable (or should just be taken into account) for temporal tiles....

I'd like to point to the comments starting at https://github.com/CesiumGS/3d-tiles/issues/102#issuecomment-3084996001 which are already covering some of this. (Yes, they are long, but I think that it can be useful to...

@GatorScott If you have specific ideas about where and how these standards and reference systems come into play here, it might be worth adding your thoughts in https://github.com/CesiumGS/3d-tiles/issues/102 . (Note...

(I only read over that _once_, but will probably have to digest it and draw connections to other issues/discussions/considerations) A high-level point: It was _intentional_ to have the same structure...

An aside, as pointed out by @mzschwartz5 internally: It might be worth trying out whether the custom shader works when the `REPLACE_MATERIAL` mode is used (instead of the default `MODIY_MATERIAL`)....

This looks like a specific instance of https://github.com/CesiumGS/cesium/issues/11749#issuecomment-1950184016 It's OK to track this in a dedicated issue. The approach that is mentioned there (i.e. a regex-based search that allows _finding_...

There still are many details to be sorted out (and I certainly didn't read through all related issues, and even less the code). But I remember trying to use "billboards"...
