Hi Sergey, I found the ive format to perform the best with combination of using S3TC textures. Try using this:
osgconv --compressed-dxt5 master.flt master.ive ... You will see big difference in loading and rendering time Cheers, Nick On Fri, Apr 5, 2013 at 10:44 AM, Sebastian Messerschmidt < sebastian.messerschm...@gmx.de> wrote: > Hello Sergey, > > Can you elaborate what you mean by fixed to flt?
