Hello, I'm new to this so I'm sorry if I can't describe the issue as accurately as possible. I just did a tutorial based on Simsina's UV mapping and got to the stage where I have done the mapping and imported it into my mesh, and try to see it in game. However I noticed that I have some weird black lines on the table leg, a shadow on the table top and the bottom of the table legs are showing? Seems like the table is transparent or something Many thanks for any guidance!  image hoster |

Looks more like it has been meshed inside-out. Can happen if you extrude edges in the wrong direction.
If you still have the Blender file, do Normals/Flip direction, then export to S4Studio again, and see if that helps.

No idea how that happened - during scaling perhaps? When I'm playing with the axis.. did it flipped my mesh in the process? For those that may face same issue and happen to see this post - go Edit mode of the Mesh, make sure the affected face are selected (in my case everything), and press Space bar -> search for 'Flip Normals' |

Can happen during scaling if you scale it across the wrong axis. Keep to one side of the mesh when scaling, left or right doesn't seem to matter, but if you start on one side and go over to the other side of the mesh while scaling, it flips the mesh inside out. You can do one very long scale in one direction though (arrow goes over the screen several times, you can lift up the mouse, move it, continue the scale that way).
Holding in CTRL and/or Shift can help with more precise scaling (you can scale in incements). Ctrl seems to calm down the flipping a bit. Zooming out also helps a bit. And you can scale several times if you need to be precise.
In Blender, the polygons will turn a different shade if they're inside out (from slightly yellowish grey to slightly blueish, often with fully dark polys too, since the normals get flipped - at least it's this way in the 2+ versions, not sure if it's the same in the 3+/4+ versions, but likely), and the polys can be a bit harder to grab if you don't have the see-through mode on. It's not too easy to see the difference (probably something that can be changed in the settings, haven't looked too much into it), but after you've worked with Blender a bit, you'll likely start to notice the difference.
I'd say just have some fun testing things out with the Blender "startup cube". Can't ruin anything, and you quickly figure out how things work.

Thank you so much! It's helpful to know and certainly interesting to pick up!
