When rendering a gaussian splat (PLY or SOG format), applying any transform causes splat to disappear

[obolland]

As described here.

I can render a splat using the useSplat hook const { asset, loading, error } = useSplat('/assets/tile.sog');.
However applying any transform to either the camera or the splat causes the splat to disappear.
There's a minimal example component within the link above. Whether the transforms are applied declaratively or imperatively, the outcome is the same (splat is removed from the scene).

This appears to be a bug as I'm not trying to do anything especially strange or out of the ordinary, however this is the first time I'm using PlayCanvas (normally ThreeJS or BabylonJS) so if I'm missing something, would be great to know what it is!

Hi @obolland , I think this is related to #298, which I'm currently working on. The technical reason is that we unnecessarily reapply unchanged GSplat props to the underlying PlayCanvas GSplat Component. This causes side effects and unpredictable behaviour like the ones you have described.

I will have a fix for it ready next week, but right now the implementation is still WIP.
