Slow render with carpet

(1/2) > >>

alebul:
Hello. How to speed up render time in scene with carpet? Carpet created by Cscatter. In one object for instances - 7472 polys. Scatter count - 100000. Without carpet render time about 3 hours, with carpet - 7 hours. Is only one way - decrease geometry of carpet?

maru:
Optimizing the scattered objects is definitely a good idea. You may also try scattering proxies instead of original geometry. Aren't you running out of RAM?

Ondra:
The most helpful thing would be if you could post screenshot of the stats sidepanel in VFB for both versions of the scene

alebul:
This is scene without carpet.

with carpet

this is object for instances

and this is task manager

romullus:
It looks pretty much normal to me. Your carpet occupies almost half image area, so it is expected to have significant impact on render times. One thing you can try is to reduce polycont of carpet. Unless you plan to put a camera inside a carpet, you can simplify fibres model a lot, like a ten times and you still couldn't tell a difference.
