Alright so another update for you.
Here to show off some models I'm currently working on. Remember, these are work in progress pictures. But you may also leave feedback if wanted to! : )
Picture 1 is Field Comm, 2 is Collapse Rescue 3, 3 is 2002 Seagrave rearmount ladder
A temporary solution for Blender users would be to export the model as 3ds or obj , and then import it in Zmodeler. Do some final touch ups, any bugfixes, center the axis, and scale the model down, then you can export it in Zmodeler as v3o.
