No, that is not so weird... I have met this when making a sailor skirt...the colar turn into a black hole... When making model in max..the terrible thing is 2 face model... But if i find out a way to elimiate this in max...The UVMapper u use in Poser...is a kind of Multi-Sub object Material in max...so, just apply it in Max and u will not encounter any problems in Poser..
