CesiumGeoreference.ecefToLocalMatrix is one frame late

Hello

I am using CesiumGeoreference.ecefToLocalMatrix as a shader variable

However it seems to be one frame late which makes my rendered items seem to float when the camera moves (even if i take it in the lateupdate)

Is it normal ?

If needed I can provide a sample

Thanks and regards

Dumb question, It was a script execution order problem. The lateupdate of the wanted script has to run after CesiumOriginShift
