Airport scenery lighting and shading

[Helexius Ten]

hi, i'm developing an airport in tunisia for FS2004, everything goes well until i notice that some of the buildings in exported to the airport have inverted shading or lightened sides that are supposed to be shady and sticks out from the rest of the scenery i made, the blue arrow is the trouble area and the red is the normal, i used blender to make this scenery, any way i can fix this? and thank you in advance

It looks like a consequence of reversed faces. This happens very easily in Sketchup, with similar results. I do not use Blender so I can speak to the likeliness of the same situation here.

How can I fix reversed faces with sketchup?

I would inspect the normals first. You can load the object in ModelConverterX as well to see how they are stored in the MDL file.

All normals are flipped outward (they are visible) but the only issue is that their shading is reversed, so light is dark and dark is light, other than that everything is fine

Could it be you have an emissive colour set on the material then?

 

[Helexius Ten]

Could be, do you think I can send you the BGL files to take a look?

 

[arno]

Yes, I can have a look if you send the mdl or bgl.

here they are! and thanks ^_^

I had a quite look at the models, but I can't see anything weird in the material settings or so at first sight.

i'll try loading them up on sketchup and start fiddling around, if anything is noticed i'll be here ^^

Hello...

Question: Upon exporting in Blender,.. did you click so that the faces are to be double-sided? or no?

 

[Helexius Ten]

Every face had one side when I exported then, it turns out mirroring can cause this light inversion and I do remember using it at one point, then I used a mirrored mesh to make the rest of the buildings, not a wise choice on my part xD I had to rebuild the hanger from scratch and it works fine now, 5 more buildings to remake xD

Finally fixed the issue!! not sure how though hhhhhh, i had to rebuild two other buildings along with the hanger and then i joined the old objects with the new in blender, and voila!!!! the red are the old working models, green are the rebuilt and blue are the the old defected buildings now corrected!, thank you guys so much for the help i really appreciate it! ^^
