Okay, so i am using 3DS Max 2012, (a legal version if it matters) to make a pair of shoulder pads... only problem is, when i try to convert it, (using the 3DS/OBJ file converter from the hive) it kills half of it... Every other triangle is gone... and i have no clue why... Any ideas?

It goes from nice looking coral shoulders, to ugly chopped up pile of crap... i spend a LONG time on the VERY difficult UV mapping, i am not very good at it at all. and it isn't an easy model. so i don't want to see my hours of work destroyed....

Almost looks like it is using another texture that has an alpha channel on it.
Try manually changing the texture in model viewer.
