Objects exported in reverse order

[micheus]

oort, I don't think the wings_export.erl must be changed. It's working as it is - in this case. As each exporter has its particularities I believe that is our responsibility as programmer work around this kind of "problem".

I took a look at the code again (I couldn't change it and test), but - in accord with you've answered me - I believe that the meshlights are being exported in this part of the code:

Code:

section(F, "Objects"),
    foreach(fun (#e3d_object{name=Name,obj=Mesh}) ->
            export_object(F, "w_"++format(Name), Mesh, MatsGb),
            println(F)
        end, Objs),

foreach just call the function passing each item in its order in the list.

If you've changed the result order when changed wings_export file, it seems that you will need only to use an other "integrator" in this code above.
Try to change the code to this one:

Code:

section(F, "Objects"),
    foldr(fun (#e3d_object{name=Name,obj=Mesh}, _) ->
            export_object(F, "w_"++format(Name), Mesh, MatsGb),
            println(F)
        end, [], Objs),

or you can use that one already existent, but reverting the list of objects before use it:

Code:

section(F, "Objects"),
    foreach(fun (#e3d_object{name=Name,obj=Mesh}) ->
            export_object(F, "w_"++format(Name), Mesh, MatsGb),
            println(F)
        end, reverse(Objs)),

and if you still need to change the ID sequence, you can use my first suggestion with some small changes to the code:

Code:

section(F, "Objects"),
    foldr(fun (#e3d_object{name=Name,obj=Mesh}, Id) ->
            export_object(F, "w_"++format(Name), Mesh, MatsGb, Id),
            println(F),
            Id+1
        end, 0, Objs),

and then you need to add the Id parameter to export_object function.
