Well, to get to the point, last I checked the Lightwave file loader did a pretty sad job on my figure model "Aurora" (see my icon button for example) . Most of that was done using voxels (they call Hipper-Voxels). Maybe I need to revised this, but even some third party renders have been able to render lightwave's models (including the Hipper-voxels) and I don't think I have had any luck in OSG - mind the fact that I've mostly used 2.8.2 and not the development version much. Oh Yea! As for shaders, One of the things that came up in one of the BOF meetings at Siggreagh was that OSG didn't embrace shaders that well and with the advent of OGL 4.1 that it would be an issue - but for me it's not a big deal as least for work projects are concerned. ---------- D Glenn ------------------------ D Glenn (a.k.a David Glenn) - Moving Heaven and Earth! ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36707#36707 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
