Boni: dont use the bumpmaps,I had a look in the folder with the dragontextures , the bummaps are about 40 mb. load your dragon, in the matsettings select every bodypart and set the bumpmaps to "None" save the scene as *.pz3 file.close poser ,open poser and load the saved pz3 file and you should have much more free memory. or open the dragon cr2 with a editor and replace every bummapcall with "NO_MAP" and save the cr2 with a different name.
