Omniverse Automatic LODs vs Manual low poly generation

How does the new automatic Level of Detail (LOD) feature in NVIDIA Omniverse compare to traditional Low-Polygon Model Generation (Blender or Maya)? Specifically:

  1. How similar is Omniverse LOD to manually created low-poly models in terms of purpose and results?
  2. How much time does Omniverse Automatic LOD save compared to traditional low-poly generation, especially for complex scenes or assets?
  3. Which method is better for enhancing workflows in terms of scalability, efficiency, and overall productivity?

Thank you.

I appreciate your questions here. However, the Auto LOD is brand new, and I do not have any data or stats on this, at this time. My only advice is to enable it and try it. However, it is a deep memory management and performance optimization tool. It is really a hidden engineering featured that will automatically work when required. If you have enough GPU vram, you will not need to worry about this. In general, Omniverse is designed for full fidelity, full details models, all in realtime. LOD is only one possible fallback for low VRAM.

Thank you for your response and insights! I understand that Auto LOD is designed to manage memory and performance automatically, especially when GPU VRAM is limited. However, I still have a few questions to clarify the best approach for my project:

Efficiency and Time-Saving**: Considering I am working on a very large scene, would relying solely on Auto LOD be more time-efficient compared to manually setting up LODs? Or would manual LOD management still provide better optimization for performance in a large-scale scene?

Thank you again for your support!

I regularly load massive massive scenes with 40 millions polys into USD Composer, with no problem. I would just keep working on your large scene and do no LODs at all, and let the code automatically determine what you need. You can turn on FSD, Fabric Scene Delegate as well for really REALLY big scenes. Go to Preferences > Rendering and you will see the option right at the top. It may even be on by default. But no, I would not do anything with LODs manually. The whole point of Omniverse is you do not have to, unless there is some exceptional circumstance.
