OTOY Forums

I'm using OctaneRender and having some problems with VRAM memory management. When working with complex scenes and lots of textures, I frequently receive errors related to insufficient VRAM. I tried reducing the texture resolution and optimizing the scene, but it wasn't enough. Can anyone share experience or tips on how to effectively manage VRAM in Octane? Is there any plugin or setting in Octane that can help me solve this problem.

Hi,
try to disable the RTX acceleration in Settings/Devices panel, to save some memory, if enabled, geometry takes more VRAM.

You can also reduce the Parallel Samples in the Kernel settings at 8 or 4 to save some VRAM, but also reducing the rendering speed.

ciao,
Beppe

There are no secrets. The data and scene have to be optimized until it inevitably reaches the hardware limit (both VRAM and RAM via OOC).

Nothing guarantees a proper optimization when stated that it has been done. Many are factually unaware of some of the best-practices and technical aspects (mis)leading them to think optimization has been effectively done when it wasn't (unless proven via scene data information in textual and/or print-screen form).

The website contains one page dedicated to sampling and optimizations that is worth looking into. Even the "best ones" can forget / overlook a detail, a method and whatnot.

Feel free to reply if it has been of any help or share any suggestion for further improvements (which are planned).

HA! This is still a significant part of my job; taking bloated assets from the creative side of the team and tracking down/cutting out the unnecessary stuff and optimizing what's left. Sure, sometimes brute-forcing it works fine when you've got plenty of time and resources, but when the deadline is looming it sure is nice to have some extra wiggle room. It wasn't that long ago that the 32 MB of VRAM on the first GeForce card was an incredible luxury that totally blew VooDoo2 out of the water.

Whether it’s through Out-of-Core (OOC) techniques to manage data that exceeds the system’s physical memory or employing Level of Detail (LOD) algorithms to adjust the complexity of 3D models based on their importance and distance from the viewer. Purchase AutoCAD LT 2017. There are many strategies to ensure that a scene runs smoothly without compromising too much on quality.
