I've modeled this time machine in Rhino and have exported it as an obj file to be used in Poser, however, the file size is so large I'd never be able to do anything with it, let alone post the model so others could use. Can anyone tell me how I can reduce the file size?

You could export it as a 3ds file, that will cut down the file size a good amount.

Well, a lot of people tend to make models without thinking of the consequences in poser. So, maybe you use 50 or 100 sides for every cylinder to make them look nice and smooth. Or make boxes and cubes with 20 sides. Totally unneccessary. I'm not dissing you. I know, because I used to do it myself in max. Then I wised up and started measuring the releationship bewteen the model in max, and the model in poser. And it can be terrifying. The thing is, it doesn't look as though you've gone over the top. For instance, on the very bottom ring, I can see the sides, so it couldn't have more than 30 or 40. I'd check some of the smaller pieces and see if you can cut down the number of sides and segments. If they're abnormally high, you may have to bite the bullet and redo them. I know all about it. I've had to do it too. mac PS What exactly is 'so large'? I mean, what size is the obj file? You can also remove normals, which poser doesn't use. That'll cut maybe 20% off the file size.

You need to look at where the extra polys are Webdancer and work out where you can remove them..for example the cylinders that make up the spokes, because they are straight you only need one height segment and i would say 24 rotation segments..also make sure they have no caps on as you can't see them...the same kind of thing on the uprights except on the bottom curves you'll need a few polys to keep the nice curve....the 3 plates look about right in the rotation segments, you could maybe do with a few more though as i can just see edging on the right side, but you can maybe save polys if you have a lot of cap segments..i've posted a pic to show you what i mean but i guess the principle is when you model use only what you need to and no more, BUT if your unsure always go to the more poly side just incase..hope that helps, Steve

Right, steve. That's pretty much what I was saying, but I forgot to mention the usual suspects - height segs and caps. Thanks for amplifying. mac

Thanks everyone. I'll give it a shot. The size of the file is 92meg which is kind of big, at least to me. Takes quite a while just to open up. But I'll try redoing the pieces to see if it helps. I'm not sure, but I think I had caps on, so that will be the first place I'll start.

92 megs is .....er.... um..... slightly HUGE, to say the least. LOL. Let us know how you get on. mac

Oh we said the same Mac i was just long winded LOL...one other thing to note is if the cylinder ends are hidden you can get the rotation right down...the ones i've shown have only 12..reason being its the ends that give away the amount of polys...eg. the disc has 48 rotations yet you can still see some edging yet the cylinders only have 12 but look ok....hope that helps a bit more, oh and post a wire frame it'll help us spot the exact areas..Steve
