Finished a model and moved it to Poser and some normals were inverted. Fine. Opened up the file (this was a single vertex object with several named polygon sets), flipped the errant normals. Back to Poser to find something in some other corner of the model had REVERSED ITSELF. This went on for a while. I got them all in the right direction eventually (was a bit like working a Rubic's Cube) but in the end spent more time than I had in modelling in the first place! Anyone else have similar experiences? An easier solution?
