strange results when rendering object in BOP dataset

[ranze666]

i need to render objects in custom rotation. when i use the script you provided to render ycbv and hb dataset, i got normal results.
but i got strange results when rendering objects in several subset of BOP, For example:
lmo obj000008

icbin obj000001

itodd obj000008

Have you ever encounter a similar situation? or could you give some advice about what caused the problem? Thanks!
