I found a way to export a .obj file to .map

How to make or export blender dae to map
As the explanation in the above link has problems with .dae files, as of 2015, and don't know why, i found another way.

First make a Tetrahedron in Wings3D. Export it as a .obj file.
Import the .obj file with Inivis AC3D. Export it as a Quake Map.
Open Quake Map with Quark. You must switch to Quake, copy "Map structure". Switch to Quake 2 in Quark and paste it.

Or you can make something and export only with Inivis AC3D.

Wings3D
wings3d

AC3D
inivis

AC3D will run for 14 days.



It is posibile that some work will have broken poly in Quark.

Warning :

DON'T STEAL OTHER PEOPLE WORK !!! MODELS ETC.
