Creating Multiblock models

[LeastReality]

Hi, I just bought Cubik and was curious if maybe I was doing something wrong. I am trying to design larger multiblock models for minecraft(Similar to those seen in Immersive Engineering) and was wondering if this was a possibility to create java obj files. Right now, when I try to add elements that are outside the 3 by 3 by 3 grid they do not really render correctly in the program, they become sort of faded out(see below image).

Thanks!
