Micheus,
I think the code I had for exporting Light Portals was wrong from the beginning. I have done some testing and think I have the fix.

lightportal ->
println(F," "),
println(F, "<light name=\"~s\">",[NameStr]),
println(F, "<type sval=\"bgPortalLight\"/>"),
println(F, "<power fval=\"~.10f\"/>",[Lightportal_Power]),
println(F, "<samples ival=\"~w\"/>",[Lightportal_Samples]),
println(F, "<object ival= \"~w\"/>",[Id]),
println(F, "<with_diffuse bval=\"~s\"/>",[Lightportal_Diffusephotons]),
println(F, "<with_caustic bval=\"~s\"/>",[Lightportal_Causticphotons]),
println(F, "<photon_only bval=\"~s\"/>",[Lightportal_Photon_Only]),
println(F, "</light>"),
println(F," ")

end,

println(F, "<mesh id=\"~w\" vertices=\"~w\" faces=\"~w\" has_uv=\"~s\" type=\"0\">",[Id,length(Vs),length(Fs),HasUV]),
export_vertices(F, Vs),

and then the following further down in the code...

case Object_Type of
mesh ->
println(F," "),
println(F, "</mesh>"),
println(F," ");

volume ->
println(F," "),
println(F, "</volumeregion>"),
println(F," ");

meshlight ->
println(F," "),
println(F, "</mesh>"),
println(F," ");

lightportal ->
println(F," "),
println(F, "</mesh>"),
println(F," ")

end,

Changes above are listed in bold font.
An example of exported code is as follows if I am not wrong...

<!--Object Name w_LightPortal, Object # 7-->

<light name="w_LightPortal">
<type sval="bgPortalLight"/>
<power fval="200.0000000000"/>

I need to do more testing but I think Light Portals are working with those simple changes. I have not had time to try compiling the suggested changes to make sure they work. I have only exported an xml file from Wings3D and manually edited it and then rendered the modified xml file. I will do more testing tomorrow but wanted to go ahead and post what I had found so far.
