(Fixed) [HOU-1792] memory tracking in vfh?

[LeoYfver]

do we have memory tracking in vfh?

Unfortunately, memory tracking is incompatible with the V-Ray Application SDK which is the base of VFH.

You could maybe export a .vrscene and render with V-Ray standalone, which should support the memory tracking.

Tried googling but didn't find any info on how to use it with VRay Standalone. Could someone point me in the right direction?

Hey, Erik,

this won't work with the vray executable shipping with V-Ray for Houdini. It will work with Standalone (and by Standalone, I mean V-Ray Standalone 4.0 that can be downloaded from the website or the nightlies section).
You could add the following to the Post Translate script so the required info is exported to the VRScene:

import vray

with vray.VRayRenderer() as renderer:
memtracker = renderer.classes.SettingsMemoryTracker.getInstance OrCreate()
memtracker.output_enabled=1
memtracker.scene_name='hipFile'
memtracker.output_directory='C:/Users/Gosho/Downloads/'
memtracker.output_file_prefix='out'

Here's what those do:

Parameters for plugin 'SettingsMemoryTracker'
output_enabled: bool = false, Enable memory report file output
scene_name: string = "", The scene name, needed for the file name
output_directory: string = "", The output directory, needed for the file path
output_file_prefix: string = "", the output file prefix, needed for the file name

Although I'm not sure how it would be useful. Please use the vray.exe that ships with V-Ray for Houdini - otherwise you may hit incompatibility issues due to changes not making it to Standalone, especially when those are made specifically with Houdini in mind.

Hope that helps!

Was thinking maybe it could help with getting some statistics to start from but if it wont work I won't spend any time on it.
Will there be memory tracking for VFH in the future? It's very useful when scenes start using more memory than you thought/planned.

Only for the next major V-Ray Core release.

Hey GoodbyeKansas ,

the Memory Tracker is now available in the V-Ray 5 builds. The thread is rather old but I decided to inform you anyway.

Best regards!
