Vanishing model?

#1

I’m having an issue with my model vanishing when I tab to apply SDS to it. Its just a simple rectangle shaped model. As soon as I push tab its gone from view and from render. Once I tab back its fine. The model is all quads.

Steps I did:

  1. Import model from silo as .obj file
  2. Scale the model in setup
  3. Switch to animate and tab to apply SDS

As an additional question I’ve also had models turn into spikey contorted shapes. The models were again all quads.

I’m sure there is a method to avoid this, any direction you can point me is much appreciated.

Are you 100% sure it´s all quads, because that´s the problem I get when I have a ngon in a model from Silo. My tip in Silo is to use the “select over 4 sided faces” then switch to wireframe mode to see if you got a hidden ngon somewhere in your model. Sometimes you don´t see them if you got shaded mode on.

I’ll double check. But I’m 99.9% sure. Thanks for the reply and suggestion.

There have to be NGons or it wouldn’t dissapear.

Wings has tools that help you find where they are. So does Lightwave. Don’t know beyond that.

Also check 1 and 2point polygons. I´m not quite sure (haven´t used LW for years), but I think that could cause problems, too.

#6

Well. No n-gons. I am not sure what is going on.

#7

Can you upload the file? I´d like to dissect it.

#8

There were no n-gons but there were overlapping faces. Once I fixed that is worked just fine. Odd.
