I'm trying to create an auditorium scene  that has about 100 seats in10 rows.  (See the attached pic).  I've created one seat and tried the replicator, but it won't give me the orderly kind of copies that I need.  If I duplicate each one, Carrara goes a little goofy with memory problems. Any suggestions on how I can do this... or does some one out there know of a good Auditorium model? Thanks!

A fre eone maybe you can find in Sketchup library, but I think is a good chalenge to do it yourself. Try to keep the mesh as simple a spossible so you can put all seats without eat so much memory. I think you can arrahge a row, group them and duplicate to get what you want.

I think that's what I'll probably have to do.  I was looking at the mesh of my chair and it's way too detailed.  Too may polygons and such, so I'll rework it and see what I can come up with.
Thanks for the input!

If you are using C8 you can use Normal Maps for more details (its an advanced bump map), free softwares like XNormal can create the map for you based in the high mesh.

Have you tried making a distribution map from the UV map of the risers?

For the surface replicator?  Haven't tried that yet.  Never used the UV mapper, but maybe now's the time to learn.  ;)
