Canceling the render takes so much time!!!

[yushi]

Hi everybody

 

I'm somehow new to vray and trying to get the hands on it.

I have a model of a building and the terrain and admit that it is BIG.

i have linked them from Autocad Architecture.

Why canceling the render takes around one minute for me?

the actual render is about 3 minutes.

Have you had this problem? or is it a problem at all?

It takes so long to cancel but it still has to load all of that objects in your file over the network. Since your geometry is linked into your file, it has to pull all of that information over your network or even locally every time you render.

 

Vray for me, takes a very small time to cancel provided I wait until AFTER Vray is done loading all of my texture maps in my scene. If I try to cancel while the textures are being loaded into the scene, I'll have a long wait until after the textures are loaded then my scene will cancel immediately.

 

I'm not sure if it's a bug with vray or not, but if you're during the load scene objects process and you try to cancel you'll be in for a wait. But, if you cancel during the rendering or light calc stages it should cancel fairly quickly.

 

I bet if you watch your render dialog progress you have about a 1 minute loading scene objects process before you get to the light calc or actual render process and that's your long cancel time.

I'm not sure if I understand you on the 'network' you're mentioning

 

but about the exact time of canceling, Actually whenever I cancel it takes a life time...

 

and i watched the vray message and here's some info on it:

-it warns of big scene bounding box

-total number of faces stored:1480241

-number of raycasts: 9468633

-max tree depth:38

 

and one other thing: during the start of render it takes long time for ' transforming vertics'

 

anything weired in statistics?

Like Elvis said-

 

Its taking so long because your computer has to buffer all the information to render the scene. Some ways to make this a lesser task for you computer would be:

 

-Instance EVERYTHING you can - thats a HUGE time saver

-User Proxy geometry wherever possible (trees and plants and cars.....)

-If you have an Nvidia Quaddro graphics card, get the MAXtreme drivers!!!

-Instance image maps whenever possible (less maps to load = faster load time)

-Use small image maps (1024x1024 px is usually more than you need)

-Clean geometry - Autocad geometry is very messy... Vray generally doesnt like it much.

 

These things, along with you computers specs, and many other factors will control how fast your scene loads and renders. Sadly, there will also be a bit of a hang on render times, but by making clean scenes, you can really minimize the wait time

thanks Mechadus

I will try all the items except Nvidia Quadro which I don't have.

about ' clean Geometry' do you mean in Autocad or is there a fast way in 3dsmax to do so?
