Hello, I am attempting to model a large factory in UE4 and I am curious about the best way to go about it, before I get too far in.
The factory in question is millions of square feet in size, and consists of only two main buildings. The smaller of the two is millions of square feet on its own.
For the main structure of the buildings, like floor, walls, and columns: BSP or modeled geometry? It doesn’t need to be an extremely accurate representation of the factory, and things like baseboards, outlets, door trim and such are not likely to be included.
The ceiling is mostly a complex set of i-beams and semi-intricate structures to support the roof and various other things.
Air ducts, water and waste pipes, electrical conduit, junction boxes, power distribution, sprinklers and lighting will all be included, at least. Major manufacturing machinery will be included.
We monitor a great deal of things and want to visualize them in 3D. There are no tools available that currently meet our needs.
I know about geometry decimation and LODs (not as well as you lot, of course) and I am aware of things like replacing small metal meshes like chain-link fence with textures with transparency that looks like the wire mesh, for example, and there are a lot of other tricks that I do not know.
Does anyone have any general rules of thumb that I can absorb? I want to model the inside of these buildings, the outside, and some of the major landscaping.
