VProxy render 2 Time slower

[sedus]

Hi,
I just realize doing some test, that Vproxy render about 2 time slower than original Mesh.

I did try many parameters, but I can't figure out What is happening.
Try To change from default to static or dynamic, increase Dynamic memory, enable/disable Embree.... no change.
Proxy are not that heavy, Memory usage is very low in both case -+ 50 mo (Original mesh or Proxy) about 2.5 Go of memory

Any clues? It is king of annoying because I have to render a full animation, and it will take Twice the estimated time.

thanks for any infos

I don't think proxies are supposed to render faster; they are to save on memory. My projects, with proxies, always render slower.

Yes I do know they are supposed to save memory, and it works very well.
But, I never realise it take 2 time more slower to render the exact object.
I only assume it takes a little bit more time to load into memory. But in Static Mode, they are supposed to be loaded once.

Hi,

I think the case here is different here. Would it be possible to give me more information about this proxy object? How is it created?
Is it a Forest pack tree?

V-Ray 3.1 is somewhat better at this, but in general when you create the proxy, there is an option how many faces to put per voxel - you can increase it to f.e. 100000 or more (newer builds also have an option "One mesh per voxel") - this will make the proxy render faster later on. Additionally, V-Ray 3.0 does not use Embree for proxies (whereas V-Ray 3.1 does), and it is another source for difference.

When will V-Ray 3.1 be available?

With some luck, next week. For sedus' scene in particular, I got the following results:

No proxies: V-Ray 3.00.08 - 2m 40s, V-Ray 3.10.01 - 2m 3s
Proxies: V-Ray 3.00.08 - 6m 25s, V-Ray 3.10.01 - 2m 54s

The proxies are still slower, but not as much as in V-Ray 3.0

Wow! that is quite a difference!
