Openscenegraph to Unreal Engine

Question

Is there a way to export an openscenegraph scene to unreal engine? So for instance perhaps export to a format supported by 3ds max or blender would be first step, if so , then how to achieve this?

Answer 1

As user Kaveh Rassoulzadegan says FBX is the native import format for Unreal and OpenSceneGraph can be compiled with support for both import and export of FBX files.

Another path can be to use osgconv export to Alias Wavefront OBJ format. Support for this format is built-in in OpenSceneGraph and do not require any external code:

osgconv infile.osgb outfile.obj

Then import the generated outfile into 3D studio Max and export to FBX.

The quality of the exported files may differ between which format you select on and it can be wise to evalute which format suits your initial model best.

Answer 2

If I am not mistaken, OpenSceneGraph appear to already propose a fair amount of file interchange plug-ins. Not sure how well they output osg scenes, but it would perhaps be worth testing them.

Have you inspected those extensions ?

As for exporting geometries toward Unreal Engine, I would recommend using a FBX exportation plugin. This should let you either export geometries directly to Unreal as well as most DCC tools such as 3DSMax or Maya.
