ok... I converted it by myself, but there are alpha channel bugs... look at this:
If the chassis_hi have the glass, You must detach this and rename to "glass_hi" (example).
How to do in Zanoza:
create - objects - by material - split - ok
Unite back the chassis_hi without glass. The glass rename like in example. "_hi" indispensably.
If the side and rear glass - is the one part - detach everyone of them and call glass1_hi, glass2_hi and glassr_hi for example.
In hierarchy it must be placed in chassis_dummy.
I wish you success!
