I could see it wasn't anything to do with the mesh as there's no intersection - and if there was, it would be visible in the Vue renders as well. I did see something about displacement being the problem, but I discarded that idea as I hadn't realised until PhilC said it again that the items that were giving me the problems all have large creases in the shoulders etc. that are done with displacement maps and not modelled in. In the Firefly renders all the low parts of the fold are looking pushed back into the figure. With the displacement off the render is fine. It only gives fairly minor pokethrough normally, but using Morphing Clothes makes it a right mess. Adding more displacement isn't going to help with that, unfortunately.

It's an Eon conspiracy! Every time I'm about to try rendering with Poser something happens to make me go back to use Vue instead! :scared: :laugh:
