Models....

Hi, i got an problem with some models, when im on object mode they dont have problems but when i press P they looks like with normals flipped, i tried flip normals but X( doesnt worked, and now i cant add them to the game, thanks if someone helps

Try Ctrl-A keys, maybe?

tried and not wrked

Maybe you mirrored the mesh? try to mirror it again in edit mode. I think it was <m>.

dont worked too

send us the .blend if you cant solve by yourself, its hard to tell you what to do if we cant see what s happening

i think you have a problem with camera.
Camera collides your object or camera view start and end have problem

go to edit mode, press a and then press F9 and go to the mesh tools tab and press flip normals and it should work, thats how i fix mine.

you can try by going to uv face then select "twoside:

you can try by going to uv face then select “twoside” and then “ctrl”+“c” then active face mode!

tststs

two-side - a very lazy option.
It doubles the faces (performance!) and might produce illumination problems.

Show as a blend, that we can have a look at it.

try recalculating normals outside, i think it is beside the flip normals option
