Help with building a city on a slope?

Unity Engine
1

Hi all, posted this in the wrong place the first time around so if I have done it again can a moderator please move it for me :S

I have an idea of a city built on the side of a mountain (think 'Rohan" with snow) but before I start I would like to ask your advice. I am new to Unity so actually I have several questions but it’s alright if you can’t answer all of them because I am very demanding :smile:

  1. I will be building the models in Cinema 4D then import to Unity. What is the best file format for this? obj? Also will any textures I have applied still remain.

  2. Should I design the model to accomodate the slope, or should I do the model first and raise the terrain around it? This is very important to me because the buildings are held up by stilts that should be stuck into the mountain.

  3. What is the best approach to create winding roads up the mountain?

  4. How can I make snow in Unity3D?

  5. How can I make this snow accumulate on the roofs of my houses and fenceposts etc?

Advice and ideas would be much appreciated! Thanks in advance

1.) Probably best building models in Maya but as long as you can export to .fbx you should be ok…
2.) If your building are on stilts all should be ok… I suggest you make the stilts extra long in case you add a building to a very steep slope.
3.)There are a couple of excellent road building add-ons…

4.) There are particle effects for snow that ship with Unity or you can find these effects for free…
5.) That is a tough one as I expect physics will most likely be required and that could be very expensive… But I suppose you could animate the effect…

I am sure you will get more and or even better assistance as others respond…
I have been creating similar projects…
Take a look at my Whistler Project and the pics and vids on my web site…

Best of luck !
