another 3DS question

[wasj2004]

Well im trying to figure out how to adapt some of these models i got. Ive learned alot from some of the posts on here! But im stuck on a texture problem. I got 1 model working by resizing the textures, and everything looks great, but there are like 3 or 4 tif images that im stuck on. from what ive read, tif doesent work in celestia, ive tryed to replace it with a jpg but i think its somewhere inside the 3ds file that tells what kind of image to go after. can this be changed? is there a way to make the model go after a jpg instead of the tif? Im so close! The model looks great except for the bright white spots on it where the tifs are missing!

wasj2004,

You'll have to modify the 3DS file to change the texture images' filetypes.

You can use either a 3D modelling program or a binary hex editor. I usually use Emacs.

Its materials and texture filenames usually are near the beginning of a 3DS file.

Don't forget that Celestia also can recognize wildcard texture image filetypes. I don't know if any of the modelling programs do, but I doubt it. In Celestia, an asterisk (*) means for it to use the first file type that it finds of PNG, JPG or DDS, in that order.

Thanks Seldon. Can you recomend a mpdeling program that will do this? Ive downloaded several i found on the net, but they either wont show textures or dont work on 3ds. I found quick 3D, it will display the models textures, but I dont think it will modify anything.

Like I wrote, I use Emacs. It's easy to find the filenames and change the filetype. So long as you just replace .TIF everwhere with .JPG, the file won't be damaged at all.

I usually use the modelling program Anim8or, but it doesn't understand .TIF either.

I did a search for the binary hex editor and found one on the first link in the search! That definately got me rolling again. Thanks! That got me down to a couple small details on the model that still arent textured, gonna search back through the model file and see if there are any textures i missed or that dident come with it. Alot closer now!

You find a lot of models made with 'Multi-SubObject' textures where more than one texture is applied to the same object these you can only fix by chopping the object up by textures so that each object has only one texture,Jestr

I noticed that sometimes there will be a texture, and somekind of shine texture that is suposed to go on top of it, and even dirt layer textures to make it look dirty all stacked together. This must be what you mean. Im gonna experiment with layering them together into one texture. Im sure it wont have quite the same effect, but its worth a try!
