Hello how are you?
I love their warehouses, all of them, I work with 3D modeling, I use 3Ds Max, I make makets and etc. I'm not criticizing, right? just a tip to improve your work. Come on, the first point is that you do not optimize your modeling, they are formed by many unnecessary polygons, for example, it seems to me that you keep the polygons even where they will not appear, as in the woodwork of the internal structures, if you "delete" the parts that are embedded in the walls already reduce the good "weight" in the models. On walls, one faces outwards and the other inwards, with "internal" structures that will not be seen by anyone, this only creates an unnecessary weight on the whole. The walls can be made only with a "plane", this object is called, there is only one side of it, it is like a sheet of paper, this is the ideal object for modeling walls, it is super light in terms of megabytes. These models have an average of 190 megabytes, it would leave around 300 megabytes, at most, the internal woodwork could be replaced by a wall with the same reliefs as the external walls, making it with a "plane". When I started modeling I was 23 years old, I really modeled everything, details by detail when rendering was more than 35 hours rendering, then I learned to see more dynamically modeling today, building a model in realistic proportions with less than 100 megabytes simply deleting what will not be seen, deleting polygon faces that do not need to be in the scene, etc. Try it with the 120x225 Shop, I guarantee you that if it ends up with 60 megabytes, that's a lot. And congratulations on your creativity, they are beautiful structures. I was forgetting, I mentioned above that I was 23 years old, yes, exactly, today I am 65.
