egg not fully rendering

Scripting Issues
1

Hi,
So i made my own egg file but Only 2 parts are shown in Pview and rendering, it only shows half of it.
Below is the egg file, any help is appreciated

<CoordinateSystem> { Z-Up }

<Comment> {
  "obj2egg room.obj -o room.egg"
}

Could you show us what it’s supposed to look like? I see a box of which the bottom face is flipped upside down.

Hi!
It is supposed to look like this!

That’s what it looks like to me, in pview. You just don’t see the interior faces (press b to enable backface culling) and there’s no lighting applied by default.

Using b for back face i now get this.
(top side)
(Bottom side)

the code i use to render the model is

from direct.directbase.DirectStart import *
from direct.showbase.ShowBase import ShowBase


terr = loader.loadModel('room.egg')
terr.setPos(5,5,0)
terr.reparentTo(render)


run()

i get

which is the other issue im having

To render an object double-sided, use setTwoSided(True).

Thanks but now instead of the being one part missing its like a box.

First, I note that you seem to be rendering without lighting (as rdb indicated), hence the flat white appearance, I believe; adding a (non-ambient) light should solve that. At the least it should make it rather easier to make sense of the image, and thus see where the problem lies!

That said, you might want to re-examine your object’s normals in your modelling program–they may be the wrong way around (in which case simply flipping them might help), or otherwise incorrect.
