Hey DC3Apilot,
Cool! Yes, it is most important to start at level one, then go to two, and not 7 or 8, etc. What they teach in an early level, is used next in the next level, all intertwined in order. If you miss a level, you are lost on the next after that one.
When you complete the level, practice doing it by memory in Gmax, making fake parts and things. When you can do it by heart, finding the tools, making parts, then go to the next level.
I didnt do the terrain level. I thought it was useless. The animation thing with the robot I did, and it was helpful in showing me where things were.
When you are done with those, then I recommend another tutorial, called 'Stupid Idiots Guide to Gmax'. You'll need to google that. I think its traded sites a few times now. It shows you how to do a WWII prototype German jet, retractable gears animations, etc. Very very very good tutorial, but you should do this one first for knowing where the basic tools are and how to use them. This second tutorial is a masterpiece! Its so well done.
Just remember though, your primary tools are move, rotate, and scale, and they are on the top toolbar. With that, you can build a plane, (model the mesh that is).
Concerning background images which require Bitmaps. We have all changed to making background polygons (flat square planes) that we attach a texture to of a 3View. You can line them around the outer edges of a center, having left, right, top, bottom, front, and rear. They face inwards, and you look through them (back sides are transparent) and when in a view mode such as 'Left', you see the background plane or polygon perfect and can start making your model in the middle.
There are variations on this technique, such as making the planes in the center and building the plane inside them, which 'appears' easier.
But... all in all, the original 'Gmax' version background views are a big hinderance and take tons of RAM and they shift alot. Totally useless. Being able to use JPG's is much nicer. I'll see if I can find a 'how to create a view box' that will help you out when you get to that point.
By the way, the P-38 tutorial is flawed. They are having you build it backwards. FS requires the Gizmo cross hair to have Green forward, Red to Right, and Blue to sky.
I couldnt find the 'background planes' tutorials, but found these for now.
