Polys&Verts's number increase 5 times after starting render
THANKS IN ADVANCED FOR HELPIING

Hi. This is most likely caused by using displacement. Try to turn displacement off, and the numbers should stop changing.

Hope it helps

[mohamedmahmoud]

thanks for your kind answer, but the problem still there. :(

BTW, why is it a problem?

[romullus]

I don't see why this is a problem either, but you can check if some of your objects has "render time" modifiers, e.g. turbosmooth with render iterations set to different value than viewport iterations, or that same turbosmooth which is turned off in viewport, but active on render.

thanks for your answers Guys,
I am thinking it is going to steal more ram during the render process.
correct me if I am wrong, please.
thanks in advanced.

Well, it will use more RAM, but that's because it is doing something (like displacement modifier, one of the several smoothing options that have higher smoothing values at render than in viewport) etc. - in other words, it's adding detail needed at render time that it can skip in the viewport to keep the viewport running more smoothly. Not wasted RAM, and "saving" that RAM would mean losing something when you render (detail, smoothness, etc.)

As to what that is, displacement or smoothing are the likely causes :)

ok, now it's clear.
many thanks for the answers.
