Error loading LOD

🌵 Needle Engine

Hey guys,
Ive been getting this error and am looking to understand what is likely to have caused it. I cant seem to find out specifically what model it relates to.

Am I okay to delete the mesh_lod_ objects from the assets/ folder? I thought that removing the progressive loading settings object, adding it back, and having it regenerate lods would work but it hasnt done so.

Any advice appreciated as always.

Hi Nostalgicbear,

The “Error loading LOD” could be related to various issues when handling Levels of Detail (LOD) in your models. It might occur if there are missing or improperly configured LODs for your meshes. Here are a few considerations:

  1. Check the Mesh Configuration: Ensure that the models associated with LODs are correctly imported and configured. If you are not seeing which model relates to the error, it might be necessary to check all the mesh_lod_ objects to identify the problematic one.

  2. Removing mesh_lod_ Objects: You can delete the mesh_lod_ objects, but this may not be advisable as it might cause further issues. It’s better to regenerate the LODs through the progressive loading settings.

  3. Progressive Loading Settings: Removing and re-adding the progressive loading settings might sometimes not refresh the LODs entirely. It’s recommended to verify that the setting for generating LODs is enabled and correctly configured in the Inspector settings .

  4. Debugging LODs: You can also enable debug logging for LODs. This will provide insights into LOD changes and can help you identify whether the correct LOD levels are applied during rendering .

  5. Consider Context: Ensure that your environment supports the necessary features for loading LODs, including verifying your materials and texture settings.

If the issues persist after checking the above suggestions, please check for any additional console messages that might indicate further issues or context regarding the LODs.

Feel free to ask more specific questions if you need further detail on any topic!

Hey, that looks like progressive mesh generation fails to generate a specific LOD here – the hash 00000 looks suspicious (this should be a hash of what primitives a mesh has).

Which version are you on?
Would you be able to report a bug with that scene?

This project uses quite an old version (3.45.2) - Im a bit reluctant to update at this stage, but can do if it will resolve.

I will raise a bug report first thing in the morning. It doesnt actually appear to be breaking anything. I cant see anything noticeably wrong with any model even from various distances.

I see. Yeah if it doesn’t have a practical impact, I’d say “ignore it” if you don’t want to / can’t reasonably update that project. I don’t think there’s a high probability of us prioritizing such a bug on an older version if it doesn’t really break something.

Hello, let me know when you sent the bugreport. It’s also possible to try decoupling the optimization from the engine version by modifying the package.json scripts. If possible try updating to a newer version first (altough understandable that this might not be an option).

Mesh LODs can also be disabled for specific meshes in Unity if you’re using 2021 or 2022 versions using the mesh importer settings so this might be another approach to workaround the issue.
