Here it goes: I have 2 3ds files; one has a structe as follows: MAIN3DS{unsigned short ID, Unsigned int Size} EDIT3DS{unsigned short ID, Unsigned int Size} EDIT_OBJECT{unsigned short ID, Unsigned int Size, ASCIIZ String} bla bla bla....everythings is ok The second file has structure: MAIN3DS{unsigned short ID, Unsigned int Size} :someting I don''t know: :someting I don''t know: What chunks could those :someting I don''t know: be? I''ve tried to figure it out already for a few days...unsuccessfully

I recommend you to get lib3ds http://sourceforge.net/projects/lib3ds/
if you want to get your model loaded correctly.
If you are just being curious at these chunks, you can learn how thw library manages them reading its source.

Thanks for advice, Azdo...I''ll check that out
