@PocoRev:
DirectX files....
There are 3 types of DirectX files (more or less). You can save the DirectX as
1) DirectX ASCII (text based) Largest
2) DirectX Binary (binary) Medium
3) DirectX Compressed (compressed binary) Smallest
With DirectX ASCII, you can actually open the DirextX file in notepad and edit it.
Now, as you move down the list (from largest in filesize to smallest in filesize) more and more programs that use the DirectX files start showing issues.
Example:
99% of Programs that can read DirectX files are fine with DirectX ASCII
50% Programs that can read DirectX files are fine with DirectX Binary
10% Programs that can read DirectX files are fine with DirectX Compressed
All this had to do is because DirectX is not really a "standard", and they keep adding properties to their DirectX format. Therefore, when a modeler program reads in a DirectX file using, lets say DirectX 8.1, they are looking for certain properties. In the text file, they parse (search) through the file looking for like "TextureMap" or something. In a binary, it is all based on positions. Well, if the format changes, then the positions are off. This becomes more of an issue when it's compressed. So now you can see why some programs can read DirectX files and some cannot.
I have only tried DirectX ASCII with FPSC so I don't know about the others. Also, beware using "Free" plugins because sometimes they put extra "stuff" in the DirectX file (like 30 frames of Animation when all you built was a box) which of course will increase the size of the file.
I personally use 3D Max and a product called Deep Exploration for all my modeling needs. You can convert anything to anything. I absolutly love the program.
Hope this helps you understand.
