Tools / Batch LOD Generator
One-Click Batch LOD Generator for Unity
LOD levels, one model at a time, is a special kind of tedium. Point this at your model library and generate LODs for everything in a single click — wired straight into Unity's LODGroup.
- Batch processing — LODs for dozens or hundreds of models in one pass.
- LODGroup-ready — output plugs directly into Unity's LOD system.
- Tunable quality — control reduction per LOD level to taste.
- Editor workflow — no runtime cost; the work happens at build time.

Why batch LOD generation?
Level of Detail is one of the highest-ROI optimizations in 3D games: distant objects render cheaply, near objects render fully. The catch has always been authoring time. Batch generation removes that cost entirely.
Who is it for?
Teams and solo devs with large model counts — open worlds, asset-heavy scenes, mobile games where every triangle counts at distance.
Why LODs are the highest-ROI optimization
Of all 3D optimizations, level of detail gives you the most frame time per minute of work. The logic is brutal and simple: a prop fifty meters away does not need the same triangles as a prop two meters away, but without LODs, Unity renders both at full detail. Multiply that waste across hundreds of props and you get the single most common cause of GPU-bound scenes. LODs fix it by swapping in cheaper versions of each model as distance grows — and once authored, they cost nothing at runtime beyond the swap itself.
The batch workflow
Authoring LODs by hand is exactly as tedious as it sounds, which is why most projects never do it for their full library. Batch LOD Generator removes the authoring cost: point it at your model library, and it generates LOD levels for everything in one click. Each model's levels are wired into Unity's LODGroup component automatically, so the engine handles the distance-based swapping with zero runtime code from you.
How LODGroup uses the levels
Unity's LODGroup swaps a model's rendered version based on how much screen space it occupies. Close up: full detail. Mid-distance: the first reduction. Far away: the cheapest version — or culled entirely. The thresholds are the standard LODGroup screen-size percentages, so the behavior is the same system Unity developers already know, just with the authoring done for them.
Generated vs. hand-authored LODs
Honest answer: for the vast majority of props and environment models, generated LODs are more than good enough — nobody inspects a background crate at LOD2. Reserve hand-authoring for hero assets where silhouette changes would be noticeable. That split — generated for the many, hand-made for the few — is how professional teams actually work, and it is the workflow this tool is built for.
LOD strategy for mobile and VR
On Quest and mobile, LODs are not optional polish — they are how you hit frame rate at all. A workable starting strategy: full detail only for objects within a few meters of the player, a first reduction kicking in as soon as objects leave interaction range, and aggressive cuts beyond that. Batch generation makes this strategy affordable because you apply it to the whole library at once instead of hand-tuning per asset. The projects that struggle are the ones with no LODs on 80% of props; the ones that ship smoothly are the ones where every prop has at least one cheaper version.
Automatic LOD generation for entire model libraries
LOD (Level of Detail) is how games stay fast: near objects render full detail, distant ones render cheap versions. The Batch LOD Generator builds those versions — LOD1, LOD2, LOD3 — for whole model libraries in one click and wires them into Unity's LODGroup automatically. If you have been searching for the best LOD generator for Unity or how to generate LODs without doing it model by model, this is the tool.
Does it replace manual LOD authoring?
For the vast majority of props and environment models, generated LODs are more than good enough — reserve hand-authoring for hero assets.
Unity version support?
Built for recent Unity LTS releases and the standard LODGroup workflow.
How many LOD levels does it generate?
Multiple stepped-down levels per model, so Unity has cheap versions ready at every distance band. Your source models stay untouched — the generated levels sit alongside them in the LODGroup.
Which Unity versions are supported?
The tool is built for recent Unity LTS releases and the standard LODGroup workflow, so it slots into the pipeline most projects already use.
Will generated LODs pop visibly?
Some transition is inherent to all LOD systems. Keeping reductions gradual across levels and tuning LODGroup screen-size thresholds for your art style keeps swaps subtle — standard practice for any LOD setup.
What is LOD in Unity?
Level of Detail: Unity's LODGroup swaps a model between high-detail and low-detail versions based on camera distance, so the GPU only renders what the player can actually see. It is the single biggest win for open scenes.
How do I generate LODs automatically in Unity?
Point the Batch LOD Generator at your model folder, choose how many levels and how aggressive each reduction is, and run it once — every model gets LOD1+ versions generated and assigned to LODGroups automatically.
What is the best LOD generator for Unity?
Unity has no built-in batch LOD generation — that is the gap this fills. Compared to doing it per-model in external tools, batch generation with direct LODGroup wiring is the fastest path from library to optimized scene.
Does it work with Unity's LODGroup?
Yes — generated levels are assigned directly to LODGroup components with sensible screen-size thresholds you can tune per project.
Can I generate LODs for an entire model library at once?
Yes — that is the point of the batch workflow: point it at a library and get LOD levels for every model, instead of processing meshes one by one.
Do generated LODs work with Unity's LODGroup?
Yes — generated levels are LODGroup-ready, so Unity swaps them by camera distance automatically.
