Hi,
That work was done by product team of the site from which I'm purchasing my 3d model. So I can tell you about the RAM only after I'll get reply from those guys. But yeah the size of .3ds model is 7mb. You can also have a look at the model here:
http://www.turbosquid.com/3d-models/...aurants/667443
They said, in .3ds file you will not get all materials and textures because .3ds is a old version so no one works on that. but the osg exporter exports only 3ds files and Vizard supports only .OSG files. So now I've surrounded with a lot of problems here.
So can suggest me any site where I can get 3d Model of a Shopping Mall in .3ds format directly without any loss of textures and it would be better I can get the .osgb file of the Shopping Mall directly.
Please reply at your earliest !!
