thanx for the reply clint the first 2 things you mentioned come with rds5.5..so Ill skip them the crashing thing..lol..rds does love to do that huh? I have a memory manager that is wonderful for Bryce..it cant do crap for rds..things still lock up if you dont shut it down (and I do have the patches) I forgot, does carrara have the four window modeller? I think it did, and that would most definately be a great improvement. how about camera memory options? you can of course save camera settings...is it easier in carrara than raydream? thanx BT
