How to export multiple UV channels from 3DS Max with empty inbetween channels?

[vyacheslav_zemlyanik]

I need to export to FBX with UV3 and UV0 mapped channels, because i need UV1 and UV2 channels to be empty.

However if I export to FBX or save, channels change their "position" from UV3 to first empty channel (i.e. UV3 becames UV1-UV2...)

Is there the way to export to the channel I need?

So I assume this as intended behaviour of FBX file format, will try .obj

Question, why you need the UV1 and UV2 empty?

having a copy of UV0 in UV1 and UV2 to keep your UV3 can work? in case the next step you do with your .fbx replaces 1 and 2 for another data
