Hi, I am making a modular sofa that is repository linked to a custom base game chair. All is good except for the single sofa section. Its not recolouring, its just grey and green. When it is joined together it recolours fine. I have attached the package.

Try this version. Like I mentioned in chat, it's only a "mostly" fix. Any time you join up pieces of the modular sofa they'll revert to their original colours, but you can change them/reset them by going into design mode afterwards and setting them correctly.

As far as I can remember, the only things which are changed are the materials text list (where I added in the "##0x1C050000!" part to the start of the string) and to the CT - Design Mode BHAV, which I commented out (it was previously erroring and resetting the object on placement).

Hopefully this version works?

Yup, works like a charm, thank you Echo.
