Hi ai_enabled, i'm going to try different models in Blender. I think that "maybe" the issue is related to the pivot point again... Although they are all at the perfect axis Z location, their pivot point in axis X and axis Y are different.
I had to learn to code a bit of Python in 3 days to make all of this work. The models are all exported by code, the XML files by code, the png's by code, the floor are decorations but the walls are turrets... Lol it was a lot of work but python is interesting for sure. It must've taken me 4-5 hours just to insert the XML nodes in code so that the xml files load in Void Expanse, but the nice thing is that it now works. I can use Python with models of Blender that I export from code and everything is done automatically for, in this case, over 100+ models.
I will try to align all of the pivot points so that they are aligned all with the same distance from each other if i can... Im not sure yet how to do this as manipulating pivot point from code in Python is not super user friendly, unless you know the API functions. I mean blender python code is scarce compared to unity c# and unity javascript.
