How to find out VRay's memory consumption?

[ojk]

Hey guys,

this may be a very basic question for you but after searching the help, this forum and the internet I can't find an answer to that.

I'm trying to find out how much memory VRay (3.10.01) needs to render a certain frame. I switched the verbosity level to "all messages" and looked through the output window, but couldn't find any information about the total memory consumption.
I found some memory information about the QND tree:

[2015/Nov/3|12:04:57] V-Ray: QND tree contains 4036 primitives.
[2015/Nov/3|12:04:57] V-Ray: QND tree takes 0.91 MB.

Can you just multiply the values (4036 * 0.91) to get the total memory consumption?

I looked into older log files from VRay (3.00.01) and found some information about the memory usage and the number of nodes etc.:

[12:47:46] OJK3000: [2015/Jul/14|18:04:06] V-Ray: Total number of faces stored: 5218095
[2015/Jul/14|18:04:06] V-Ray: Max tree depth: 63
[2015/Jul/14|18:04:06] V-Ray: Average tree depth: 30.0278
[2015/Jul/14|18:04:06] V-Ray: Number of tree nodes: 1825801
[2015/Jul/14|18:04:06] V-Ray: Number of tree faces: 14959583
[2015/Jul/14|18:04:06] V-Ray: Number of tree leafs: 792414
[2015/Jul/14|18:04:06] V-Ray: Average faces/leaf: 18.8785
[2015/Jul/14|18:04:06] V-Ray: Memory usage: 493.65 MB

But these kind of information I don't find in the output window and the render log (with VRay 3.10.01).

The other way I have right now is to observe the task manager... but thats a rather clumsy way
Do you know how to find out the memory usage for single frame rendering?

Best,

Except for the task manager, there's no other way right now. There are some messages about various components (like the QND tree, the SD tree etc) and they are in the 3.10 log (just checked), but there are other components that take up memory as well.

More detailed memory statistics are on the "to do" list.

Best regards,
Vlado

Ok, thanks! Good to know, that you have it on your to do list.
