I don't use Amapi anymore,but I can say that Amapi6 while still a little buggy,is ALOT more stable than both 4&5. I even found it more stable than the Amapi7 demo I tried,(please note that was the original demo..no updates,or patches). Plus Amapi6 was the first version to import/export obj files....a big plus for Poser use. For the price of the magazine,you just can't go wrong. SWAMP
