Getting Started
Automatic Runtime LOD provides a LOD system completely done at runtime. This can be useful for a variety of reasons:
- Hassle free way to apply LOD to static and skinned meshes
- LOD handling of procedurally generated meshes
- LOD handling of meshes that change during runtime
Setup
Setting up Automatic Runtime LOD is as easy as attaching the script to a GameObject that has MeshFilters or SkinnedMeshFilters or that has childs that have these components. The script will recursively search and keep track of them. Next a “Viewer” needs to be configured, this usually is the Main Camera of the scene. The viewer what we use to calculate when to switch the LODs.
That’s it! Enjoy using Automatic Runtime LOD and for any questions don’t hesitate to contact us at help@leastsquares.io
AutomaticLOD.cs:
This is the main script of the plugin, it takes care of detecting and calculating when a mesh should be simplified, it also batches requests and executes native code in order to achieve maximum performance. Attach this script to any GameObject that contains children or has skinned meshes or static meshes that you want to simplify.
AutomaticLOD.cs Script Reference
| Property | Type | Description | Default Value |
|---|---|---|---|
Viewer |
GameObject |
The GameObject we should keep track of. This is usually the Main Camera | None |
LOD levels |
int[] |
The different levels of detail to have. In other words, how many different simplified versions of the model to generate. More levels means a more smoother transition between LODs at the cost of performance. | [0.1, 0.4, 0.6, 0.8, 1.0] |
Max distance |
float |
The maximum distance from the viewer where the simplification happens. In other words, the point in which the most simplified version of the model is used. | 32 |
Max simplifications per frame |
uint |
How many objects will the system simplify per frame. A higher value means LOD changes faster but performance is penalized | 1000 |
Target error |
float |
The target error of the simplification process. A higher value means the algorithm will care less about topological features. | 0.05 |
Smooth |
bool |
A bool that represents if the script should smooth out the resulting mesh. | True |
FAQ
Cross-platform
This asset works on iOS, Android, Windows, Linux and Mac. In case you or your team runs into any issues please don’t hesitate to contact us at help@leastsquares.io
What type of meshes?
This asset works with skinned meshes as well as normal static meshes.
Meshes don’t show
Some mesh formats need to have the option “Read/Write” enabled for the plugin to work properly. This is the case with FBX. For more information check out Read/Write Enabled
