Impressively detailed model.
If you are using modifiers or references to the mesh components (not sure of the terminology in Maya), you have to either apply the modifiers (so that they are apart of a single model) or grab those components individual and do the repeating manually within Hifi.
I suggest usually applying all the references dealing with the base mesh (everything apart of the main structure), and any repeating objects not apart of the main structure (or which are just decorative and have no functionality ) can be separate objects.
I’ve noticed that for larger models, if you look away from the origin of the entity, and the model used by the entity happens to be huge, it may get culled by the rendering engine (because it assumes you don’t see it, example in
laboratory/-253.7,646.5,110.3 (just look around you ). I think it should also check if we are looking at the bounding box of the entity/zone CC: @sam
However I think also has to do with the coordinate system; getting the objects scale outside of the domain zone its best to start modeling in, forexample, 8000, 100, 8000 which would be around the center of a “domain”. (after all, you should have over 16km volume ( which… seriously should be enough ). The red boundary you are talking about is probably the X axis indicator at the edge of Y. You can see your current coordinates by going to View > Stats.
Not sure for maya (I use blender) but check the fbx export’s settings and make sure it is ratio is 1:1 to the settings in Maya. @Ozan might know more on that.
But again, welcome to the Hifi Alpha
Just remember that because it is alpha it is a tad bit buggy, but youll get used to them, and they will eventually get solved.
