Mesh with some faces facing opposite direction?

Support Basics & Interface

Hey so I’m making a mesh for a game character and when I use the ‘f’ key to create a new face (which I wasn’t doing before) it makes the new faces with the light grey color, while the other ones are dark grey, indicating they are facing in opposite directions. Will this be a problem later on once the mesh is done? I don’t want to make a fatal mistake early on and pay the price.

Thanks,

you need to check all the face’s normal and flip the ones that needs too!
get use to this it happens very often!

Ok got it so I just select the face and ctrl n to flip normal.

for most faces should be ok
but still have to check out all faces to see if some are still flipped!
and manually change these!
