Hi.

News & General Discussion

First off I just want to introduce myself.
My name is Cian Mc Grath and I’m an architectural visualizer and animator from Ireland.
I’ve been looking at Unity the past few days now and it looks like the right tool for me.

Just a few questions.

  1. I’m hoping to create a 3D model of my home town of Cork.
    I’ll be keeping the poly count as low as I can but it’s still a city.
    Would this be too large a poly count for a browser based game?

  2. Can you set up web links within Unity? Say you had a person standing outside a 3d model of a hotel or something where they were able to click on a link and that hotel’s home page popped up in a new browser?

Cheers.
Cian.

  1. Not at all, but you’ll need to make some draw-distance limits, etc… I’d be more concerned about how its all lit and textured… Models themselves don’t take much memory.

  2. Yes :slight_smile: Application.OpenURL(“http://www.google.com”)

  3. Oh there wasn’t a 3.

Yes, exactly, JT. Cian, you don’t want it to be to large or it’ll lag like crazy. Especially if it will be a web game. But I understand your uses for it. I think it will turn up great!

Thats not what JTBentley said.

You can very much make it extremely large, you just have to properly optimize it. For example, having hundreds of thousands of triangles on screen (assuming modern hardware) is not a problem, as long as there arent too many draw calls (each separate mesh and/or different material is a new draw call) and lights.

Thanks for the reply lads.
The detail is going to be in the photo textures I apply to the surfaces. Similar to google earth. I’ll extrude large surfaces like pillars but I won’t be extruding windows and doors.
I will also optimize the photos as much as posable in PS.

The web link thing was probably the most important thing for me. Thanks JT.

If I was lighting this in Cinema 4D I would simply use 1 directional light with a hard shadow for the sun and setup the photo textures to be self illuminating.

Is it similar in Unity?

I would also like to add traffic/ people / sound etc to give people a true sense of the city.

Thanks again.
Cian.

Whether it’s a web game or not doesn’t make a very big difference. It’s still Unity running whether you’re launching it from a web page or not. The main concern with web games is size, so it doesn’t take too long to download.

it might be worth breaking up your city into segments… for example if it is two hundred thou make each city block fifty thou… if my memory serves me correct its less memory intensive…feel free to correct me if i’m wrong community

Thanks for the info Oxygen.
Just bought the Unity Game Development Essentials book so hopefully that will give me a better understanding of Unity.

Cheers.
