different result from preview windows

[tangxii]

Hey guys
yes I have reader the post------ Frequently Asked Questions ------
but,I followed the step,nothing changed.

the left is final render result,right is the preview image
as you see,there is big difference between then,especially the shadow detail.
Please,anyone know the reason?
thanks

Who could know without checking and testing your scene content? Propably you missed somethings like LV vs. PV aka Editor vs. Render.
Are you sure that you're using Geometry Control = "Auto detect" or "All movable" options in render settings?

I find the reason.
the trees outside the windows can't be recognized by Octane.
