Hi John, Here I am back about Blender. When you said, don't forget Blender, I do not and have tried to do some work wit it. From Blender, there are several exporter: osg models, fbx, 3ds, collada. Which ones are the best exportes from Blender to OSG ?
I installed the plugin from Cedric Pinson, but I had troubles about the resulted exported file when viewing with osgViewer (missing parts, bad texturing, etc.) ? Which ones export animation/armature ?
