GZDB, and thusly GZDB-BF, [url=https://i.imgur.com/usyibXF.png]import/export[/url] wavefront obj files as Terrain.
From the [url=https://i.imgur.com/BZ5fDyK.png]Refmanual[/url]

For actors, such as weapons, monsters, various objects, etc, use MD3.

if i model in Blender,which Blender output format should I export to import into GZDoom Builder?
The possible output formats of Blender are:
.dae
.ABC
.3ds
.fbx
.ply
..obj
.x3d
..stl

.md2 and .md3. Quake formats. Gzdoombuilder and both gzdoom doesnt support .obj.

Hi,

I tried to import a .obj file into GZDoom builddoom er but it did not work!
So I intend to convert this object type file.
[b] In which other 3D format should I convert it to import to GZDoom Builder?[/b]

thanks
