Hi. My mesh that I created is pitch black. Every bit of the mesh is. I think that my “normals” are upside down. But how do I change them? Thanks guys…
Select object : Right click it
Go into edit mode : Tab
Select all : A
Re-calc normals outside :ctrl n
In edit mode, press “A” to
select all vertices. Then press CTRL+N to flip normals.
Also, if this does not work, press the Double Sided button in the edit menu (F9).
 BAH!!! Beaten by Rob by mere seconds! 
if you mirrored the mesh, fliping normals wont work.
find: ------- VertCOL | make | <------------------------- button -------
hit make then it turns to delete. then hit delete. this should make mirrored mesh change to normal colours.
Ok yea I did mirror the mesh. I’ll try it. Thanks all of yall!
I got it! Thanks guys! I actually had to do a combination of everybody’s posts. LOL. Anyways, thanks again!
