I wonder what is this "instancing" iToo developers keep referencing, since so many actions break it.
Is it really bad if we break it, can we do it in some cases, in what cases this is not recommended, when must be avoided, when it is ok... etc
How can I test to see what what my style loses by not using instancing?
I tried this:
This is 100m x 100m plane with floor style applied and a teapot of course, scene would not be complete without a teapot.
Full Instancing at work:
scene file size: 0.5 M
render time 16s.
Full render: time from click to responsive max: 28s
Floor collapsed to editable poly:
Scene file size: 68.7MB
render time: 13s
Full render: time from click to responsive max: 18s
Floor collapsed to multiple editable poly via railclone tools:
No Items: 42190
Scene file size: 88.4 MB
render time: 18s
Full render: time from click to responsive max: 12m:48
My conclusions so far:
> Once collapsed,- you can't edit your parameters,- you must be happy with result. Fair enough, good enough.
> Viewport performance is lost- well i can use boxed mode, but i like Point-Cloud (mostly often for complex scenes) Though Point-Cloud too not always work on nested segments.
> FileSize increases, but i see no problem here. Xrefs are my best friends since long time ago.
> You lose texture mapping- so check that after collapsing.
> I did not monitor RAM usage, but seems it was constant throughout those 3 tests (not sure)
Any other aspect we should be aware of?
