ok. i just make my first aproach to load object with texture in simple way.
what i discover.
in .3ds works better than .obj, i don't know why.
is important to use short name for textures, because large name are cut, i don't know why that too.
This method works for me now, i use the chafari post to know commands for make this small code.
in the future, i go to try to load more textures, mor properties like color, alpha and make a function to simulate blitz3d Loadmesh - loadanimesh function.
i tested whit a hangar for tora tora tora, a 3dsmax 3 objects, whit 3 materiales
i clean the scenes material 2 times to have a clean file.
file$ = "menu_hangar.3ds"
path$ = "\objects\menu\"
menu_obj = loadobject(path$ + file$,1)
childs = GetObjectNumMeshes(menu_obj)
for i = 1 to childs
textura$=GetObjectTextureName(menu_obj,i)
textura$ = path$ + textura$
menu_tex = loadimage(textura$)
setobjectmeshimage(menu_obj,i,menu_tex,1)
next i
