<div dir="ltr"><div>Hi Thomas,</div><div><br></div><div>I had others might provide some guidance as I don't have any experience with Blender to share. The best I can do is provide general tips.</div><div><br></div><div>The OSG file format contains all state and internal nodes of a feature rich scene graph, and the structure of the scene graph can be a deep hierarchy.</div><div><br></div><div>The .obj format is a very simple format and can't represent the majority of the OSG's scene graph, so exporting from OSG to OBJ will only work well for very limited scene graphs.</div><div><br></div><div>FBX might provide more capabilities, but again it won't represent much of the OSG's scene graph so again there will be limits about what you'll be able to export.</div><div><br></div><div>The OSG tends to be used for final graphics applications rather than for data exchange, so the data tends to go from FBX/OBJ etc. to OSG.<br></div><div><br></div><div>Robert.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 22 Sep 2020 at 13:05, OpenSceneGraph Users <<a href="mailto:osg-users@lists.openscenegraph.org">osg-users@lists.openscenegraph.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello,<div>I hope I can ask my questions here in this forum. If misplaced - sorry. Let me know if and where I can place them, if not here.</div><div><br><div>I tied to run the osgconv.exe with different parameters on a model I created with MATCH-3DX (see screenshot about data structure) to create a textured OBJ mesh. It doesn't need to be OBJ. It can also be FBX or some other format I can read with Blender. </div><div>Here some of my command lines I used:</div></div><div><br></div><div>osgconv DSM_Mesh.osgb DSM_Mesh.obj</div><div>osgconv -O OutputTextureFiles DSM_Mesh.osgb DSM_Mesh.obj</div><div><br></div><div>The result is a small blank OBJ file without any geometry and texture. The reason may be the data structure from the OSGB output, which is a LOD OSGB, storing the OSGB result in multiple tiles of different levels.</div><div>I used the osgviewer.exe which can read the result perfectly, therefore I hoped I can use it in the same way for the conversion.</div><div><br></div><div>I used OpenSceneGraph Library 3.6.5</div><div><br></div><div>Best regards,</div><div>Thomas</div><div><br></div>
