Hi all,
nearly every time I work with background images in gmax, I get this prompt: "Background image will take more then X MB (usually 100MB-300MB), do you wish to continue?
the images I work with are no bigger then 70k, and they are all in grey scale. why do I get this prompt, and how do I get rid of it?
Thanks
Liran Bar, Israel
p.s.
Happy Shavo'ot every one!!!!!!! (well every one who is jewish ofcource)

By tossing the idea of using viewport background images and mapping the images to boxes/planes.

Make a four sided plane, map your backdrop image to it.. you move your plane to the correct position. so you can build your model against it... or am I missing something here?

You have missed understood me.... I am not talking about designing the whole plane with the image. I was only talking about the wing, as it is a very twisted and bent abject, so I thought it would be easier to manipulate it with the image in the background... am I wrong?

Whether FSDS or gmax, I'll build the wing with the image in the background. If you have a complex wing - you still have a "flat" background in all views, so you're still building against the background image.
In gmax, by having your scaled backdrop mapped to an object, in this case, the plane, you can move your plane back and forth as needed.
Remember, you would be mapping your backdrop images to at least three planes - top, side, front view....
I've seen modellers that using this method make "jigs" - reference planes at the different cross sections

read the John Mackay tutorial (link at
http://www.freeflightdesign.com
Tutorials Section on gmax backdrop image mapping to boxes.
Map your project's top, side and front views to the correctly scaled/sized box or plane, and build your wing with a non-moving "backdrop".
Alternatively - build a nice straight-winged, round bodied, fixed gear Arava, and don't worry about compicated shapes...

LOL......
I was trying once to build the Arava but abandoned it... (was too difficult for a beginner I guess)...
If you want I can show you what came out of it......
But anyway, somebody is already doing a beautiful Arava...
Liran is pretty new with these 3d programs, and he is already building a pretty weird and complicated (most of it) airplane... I don't think he want's me to tell what A/C.......

Erez - rumor has it that Liran went hunting abou tsome of the air bases for ideas and he's ended up making a OuragaMystereshKfir?

An Arava modified with the tail booms being two Magister rear fuselages and Vatour wings?

Well I'll give you one small clue...... It's not Israeli made or Israeli air force airplane (can you believe it???)
By the way Liran, I saw him today on TV.....
Well sooner or later Liran will have to tell the world what is he up to......

Back to liran_bar's original question- how to get rid of the message prompt.
If you're using the background image with lock/zoom and pan the only way to avoid this prompt is to never zoom in for a close-up of the mesh. Even though your original image is only 70k - the software is trying to maintain the aspect ratio of the image to the objects in the scene. So if you zoom in on a section and the view is now 300 percent bigger than the original view, the software trys to blow up the background image 3 times. That's part of the reason why it says it needs 300 MB of memory to create the new background image. There's also the problem of the image shifting around when you zoom in and out a few times. These are the two reasons why I recommend to other modellers to make textures using their background images and map the material onto boxes or planes, and then position the boxes beind the mesh as needed.

I've noticed that in gmax (and other modelling programs) mapping theimages to reference boxes/planes is more or less the "standard".
As to complex curved wings, the best example I can give you would be modelling an F4U Corsair's inverted gull wing.
I would either start out by modelling the wing "flat" against a top view background, then "pulling down" the cross-section/points at the point where the anhedral inner goes to dihedral... OR, model the inner and outer sections separate from each other.
There is no "right" way to model something.
