The Child package (bacon) is picking up the default texture from the parent (burgers) but not the recolour? Both mesh groups are set as recolourable. I must have made some error, but I just can't spot it.
Only the tray is repo'd, and not the bacon and burgers? Just clarifying.
You need the whole string for the "tsMaterialsMeshName" - with the "##0x1c050000!" but without anything at the end. The correct string for yours would be
##0x1c050000!sculpturetrayospheres-[aysarth-18.2.2021-b1b30]

Thank you! I knew I must have missed something obvious, but I just couldn't spot it.
