1) Find the original object (the pile of clothes). Clone it without changing anything (untick all in the object workshop except default colors) and make a default replacement SHPE and a default replacement GMND for it with the recolorable block set up AND a materials mesh link for the repo in the GMND. Materials link to what? To your next object. See 2.
2) CLONE the pile of clothes, give it a new guid, and make it so it doesnt show in the catalog (untick everything in the catalog tab thing in OBJD). This thing needs to be recolourable etc etc.
3) Go back to object1, link up the materials meshname GMND block and SHPE to object2 and in theory - et voila.
See attached. I actually edited the clothing tool to point at your repo'd pile of clothes. Which I gave a new guid and repo'd and made not default.
Look in the text strings of the clothingtool. See where the (no longer) pileClothes points to now?
YOUR TASK: Make the merola thing work the same way. You need to change that text string to be the same as the one in the attached clothing tool.
