Vilters, partial smoothing doesn't work on this model.

It's the running boards that bulge out when you use Firefly smoothing. (Among other things) And they are part of the body group.

Another problem is that the bodyparts are just split to keep the sharp creases without adding any polys by bevelling edges.

Makes it very hard to smooth adjacent bodypanels.

You really have to smooth everything manually and then stitch it back together.

It's a shame, really.

There are other Bugs out there that are smoother, but no one catches the shape of the original that accurately.
