I'm trying to create a slate roof using railclone. I modelled 4 cupa slate tiles in 3DSmax and mudbox. They were 800K polygons imported, which probably was too heavy so I reduced them to 7000 polygons each. But when I try to render the scene (the roof of the smallest building, my lightcache takes FOREVER. Have I made an error in my style maybe? I've attached a few screenshots. As you can see I have 4 segments which I mirror each around a different axis I then put them in a randomizer. I also have the same segments but scaled 50% every other row, so I can get a stretcher bond, also mirrored, in 3 ways and randomized. Those 2 randomizers are in a Sequence that is connected together with the first randomizer in a conditional with an X counter equal to 1. I would have sent the file but for some obscure reason it's 2,2 GB big. Is that normal for a few splines, 4 slates of 28000 polygons in total and 30 railclone objects. I don't really have a way of calculating but I'm estimating the total shouldn't be more than 70 000 000 polygons. My test wasn't even more than 20 000 000.
Also the scene consists of 30 something RAILCLONE objects, for each roofsegment I have created a new style. Maybe this is what causes it? I have a dual XEON e5 2695v2, 64 GB ram, Nvdia quadro K4000. I don't think it's hardware related.
