Checking VRAM usage and texture optimization

[madssigurd]

Is there a place to check how much vram octane used during a render? I am currently trying to optimize a scene and checking if using the texture_image_rgb node uses more vram than the texture_image_greyscale, as is explained in this blogpost on octane for c4d: https://help.otoy.com/hc/en-us/articles ... t-Textures

The Solaris implementation of Octane seems a bit wonky to me, and I haven't messed with it in a long time. If you can't find the Octane>Settings>Devices>Device Settings, you can try exporting to ORBX and opening your scene/texture object in Octane Render Studio. You should be able to export ORBX from a Render Output Node. Once in Render Studio, the Devices info is in one of the main Preferences tabs.

The Devices info in Render Studio won't tell you about the other VRAM overhead from Houdini, but the texture usage info should be the same regardless of host program.

This is clearly just a workaround if nobody else can give you a more direct way of checking.

Thank you, that way of doing it works well! Of course not ideal in the long run, but for now it helped solve my problem.
