Actually, I'm trying to use nicoli_s's mdl imp/exp script. But, I'm still confusing. When I delete vertices and try to export it, it says "Unable to Convert: Undefined to type : MaxObject"
So, All I just wanna say is, it doesn't work now. and he said check more info to look out tut. Anyway i coudn't find the tut neither.
Can someone help me? |
