Best practice to set up a large scene- lots of houses!

(1/2) > >>

Hi all

I am trying to work out the best practice for creating large scene files (large housing development, a lot of different house types and lots of instances of them) that does not slow your PC down to pretty much unusable.
Using 3ds max, Corona 8 and including features such as railclone for roofing tiles.

I have been exploring the use of xref objects but even with this method, the viewport is very sluggish to the point of unusable. Scene file size on disk is small which is great but not able to use the scene to build the landscaping around the houses.

Similar issue with xref scene in terms of slowing down but with the added problem of having to bind the xref to a dummy to be able to move it, mirror it etc.

Sure I used to use vray proxy many years ago, but converting railclone to corona proxy destroys the railclone, I'm not convinced this is the correct route to go down.

I am sure there must be a best practice for creating such a scene but struggling to find any good resources online.

The attachment shows a typical house we may build, simple poly modelling with a railclone roof.

Question is, whats the best way to populate a scene with lots of these. There would also typically be more house type variations and multiple copies of each

Also, to note, PC spec...
Ryzen 3950x
64GB RAM
GPU Nvidia GeForce GTX 1660 Ti

Many thanks in advance.

Why don't you simply collapse the Railclone object to mesh and convert the entire house to a corona proxy? Plus if it is a large scene and to be viewed from a distance, then maybe you could replace the roof geometry with texture.

Many thanks for your reply.
That is the method I have been using but collapsing railclone to a mesh creates two problems...
1. this increases the file size a lot as it is losing the functionality of the railclone
2. when the railclone tiles are collapsed, the embedded railclone material no longer works and you need to assign a new material, etc

I could use a texture and some are now very good (corona library and poliigon have some that work well) however along with street scenes and aerial views where you could get away with this we also need to produce individual house images, so closer to camera and the textures never look quite so good. It is perhaps something worth exploring a bit more though.

thanks again

X ref part of the scene, so buildings, landscaping, and cameras all seperte, could have a number of Buildig sets x refed.
Thats the only way I have found to handel lots of Polygones, and display them as boxes when refed in.
64GB of Ram , could be an issue, need to spend some money and bring it up. Makes a big difference.

davevc:
many thanks for your reply.
We have been using x-ref, you are right, it is definitely the right workflow, or seems to be.
Have been thinking about RAM, will perhaps have another look and see what costs involved.
thanks again
