SOLVED one-sided mesh

for some reason, the hood, trunk doors, everything! appears to be onesided, from one side, it is visible, but from the other, it is invisible

 

I believe that's expected behavior. If you want to have two-sided mesh, you can either duplicate and flip the existing mesh (dirty way) or use solidify to make a proper inner part.

 

Or you could add

Code:

"doubleSided":true,

to the material

 

I'm not a fan of this one as it is sometimes buggy (and it applies to every mesh using that material, adding unnecessary overhead), but yeah, that's an option too.

 

thanks a lot everyone!
