Attached Link: Large CITY Flythrough

A WIP showing most of the East End of London (as proxies)  in a single Carrara file!

Only takes 1 min 20 secs to render on a single i7 machine per frame (I had to work hard to get the render time down).

Video covers some of the tactics I’ve used, but as this is a WIP I’ll do a full set of tutorials when I know It’s fully done.

Nice. I haven't had a good excuse to get City Engine yet but it's definitely on my list. I'll be interested to hear how Carrara does when you start replacing the proxies. Carrara has polygon reduction for objects further away from the camera, but only for products made by DAZ3d. 

I see more RAM in your future! :D

Ha ha - certainly for CityEngine 8GB is not enough for a city this size. Prob need to double it, but I've not been impressed with how Carrara copes with larger files (loading/saving/rendering/editor etc).

So I've deliberately aimed for small being beautiful. Of course that starts to fall apart when the proxies are replaced, but I'll fight it to the last.

Nice model and render.  Looks like it could produce some impressive images.

Wow! Very impressive. I wonder what's the size of your file. Even with minimized shaders it must be huge.

But I am also wondering about replicators: I see you are using some (judging by bounding boxes in fly through), but are the smaller models there in instances or are they also replicated all over? I wonder whether it would improve the time/storage/memory to use lots of distribution maps and replicators with few actual instances, or whether with really low poly models it's actually resource-cheaper to use them instead of the maps?

Kixum - thanks

Antaran - I'll cover this in more detail in a future set of presentations, but there are lots of considerations. One of the biggest is your time.

City engine will save masses of your time at the cost of instances (unless you have the budget for the advanced version which outputs FBX - but even that brings compatability problems).

For this you are stuck with models. However the models are bunched into "super models" i.e. lots of houses in one object - which is quite efficient.

I am using the surface replicator for the trees, but this is no good for the houses (not acurate enough).

More detail to come in a future vid.

Glad you are enjoying the show!

Thanks for that.  It looks like it will be great.  It is waaaaay above the abilities of my meager two core machine.

Yes that would push it for a 2 core, BUT would you believe just the houses alone (without poser characters in them) are very quick to render, so if you wanted to do a flythrough only it might be possible.
