Blender Import Issue (Building partially rendered)

[konjiki7]

I'm relatively new to blender but seemed simple enough to pick up.

My first mod has been creating a Geothermal Power plant as its major source of energy not included in the game I will be posting a like to [WIP Mod]

Here is how blender is rendering the building

Here is how the CS is rending it.

Notice some of the walls ceiling are missing unless you look at the inside of the building. Its almost as if the building is being rendered inside out....

Any thoughts on what could be causing this?

Looks like a problem with the normals. Try to recalculate them, then turn off the little (fax) normal markers and look if they point outside.

100% because your normals are all skewed.

Try selecting it all and ''recalculate'' under the UV tab on the left. If this still gives odd results, you've modelled it with odd angles, so manually click each side that is a darker shade, then recalculate face by face (press flip direction button under the same tab)

Okay that worked great for the brick building. For the cylinder smokestacks i used solidify which seemed to fix the missing face issue when rotating the building in game.

Solidify = Ctrl+F for those who may have this issue too.

Cool thing is this didn't mess up the texture map!

Solidify would work because it tells the anti-normal faces are within the solidified surface
