I realise that this topic hasn't been used in a while, but it's relevant to the issue I'm experiencing. At least I think it is. I have read through the whole tutorial you mentioned, and as far as I can see it doesn't address what I'm struggling with. I may be missing something, but the issue I am having is that each segment I am using has itself a multi/sub-object mat assigned to it. So to create my RC material, I have a Parent multi sub mat with 8 slots, and each 'child' material slotted in is itself a multi sub material. (I am creating 8 different beauty product items...eg cologne and body lotion etc, that are being assigned to a RC library shelf using RC linear array).
So the problem is that when I render it seems like RC is getting confused re material IDs, as mat ID no. 1 is assigned to a few different things (not just one segment but for eg also the label on that segment and the spout on another segment)
I will post images to explain. The one render is the Railclone object with the material I described above assigned (image attached). Materials are all mixed up.
The other render with fewer bottles I just manually placed two instances of each bottle on a shelf for you to see how the materials SHOULD be rendering. Eg the eau de toilette bottle third from the right has a multi sub mat assigned to it consisting of 4 different materials.
I'm sure it's something quite obvious, but I just don't get it. I'm pretty sure I don't wire in a material operator as I don't want to randomise anything...just maintain the materials already assigned.
Thanks in advance,
