What should be the dimensions of 3D models in Unity3d?

Question

Unity

I started making a 3D scene in Unity, downloading all sorts of .fbx models, but they are all different sizes (they were terribly huge). I know that you can increase / decrease them, but if I put a camera, what sizes will they be? How are the giants? :)
Advise the newbie how to be?)

Answer 1

In general, officially the unit advises to model taking into account the scale of the default cube, like 1 meter type. in the import settings there is a scale fad, so you can change it if necessary.
taking a scale corresponding to the size of the cube is necessary for the normal operation of physics. if physics is not needed, then you can do whatever you want. for the engine, no matter what size the model is, it matters how many polygons it has

Answer 2

Installing the camera will not affect the size in any way (poziki, nix, he installed the camera, everything quickly decreased!). The size is generally a relative thing, maybe you zoomed in very much :) You can compare it with the default cube. Well, when importing, you will have to set some kind of coefficient.
