# AutoLOD
|
||
|
||
AutoLOD is a very simple tool that will generate a LOD group with any 3D
|
||
object from your scene. It will automatically compute simplified version of your
|
||
meshes using decimation.
|
||
|
||
## Setup
|
||
The whole package is contained in the AutoLOD folder resulting from the import.
|
||
You can move it wherever you want, but it is recommended to keep the same
|
||
folder structure.
|
||
## How to use
|
||
AutoLOD consists in an editor window. You can open it via Window->AutoLOD->MeshDecimator.
|
||
|
||
Put the object(s) to be processed into the ”targets” area. Please note that
|
||
a Renderer is required otherwise the object cannot be added.
|
||
By default, the same presets will be applied to every renderer in the list.
|
||
You can customize these presets in the Custom Settings section.
|
||
You can also customize per-object settings by folding out targets in the list.
|
||
|
||
Both settings panels are identical, meaning that each object is fully customizable independantly from others or from the common settings.
|
||
|
||
The LODGroup Settings foldout let you control the LODGroup setup as
|
||
it should be when created, but you can still change it manually when the
|
||
process is over. You cannot interact with the LODGroup widget (which is
|
||
NOT the actual widget, but just a representation), only the sliders LOD Levels,
|
||
Seamless/Performant and Size Culling will influence it.
|
||
|
||
You may want to save the decimated meshes to the assets. You just have to
|
||
check the Save meshes to Assets toggle and enter a path. If the path does
|
||
not exist, the program will automatically create it for you.
|
||
When you are ready, just click on the button Generate LOD.
|
||
|
||
## Features
|
||
• Minimalist interface and really easy to use
|
||
• Works in both edit and play mode
|
||
• Works on prefabs instances (no need to unpack them)
|
||
• Generated objects can manually be saved as prefabs as long as the toggle
|
||
Save meshes to Assets is checked with a valid path.
|
||
• Generates up to 8 LOD for a single object
|
||
• Decimates UVs (from uv1 to uv4) and bone weights too.
|
||
• Compatible with sub-meshes
|
||
• Creates colliders for simplified meshes (if the source has one)
|
||
• Can be used for simple distance culling too
|
||
• Fully compatible with any render pipeline
|
||
## Some tips
|
||
• A demo scene is provided in the Scene folder: click play and follow the
|
||
instructions. The provided material in the scene should appear pink in
|
||
LWRP/URP and HDRP. Feel free to upgrade the material to your render
|
||
pipeline, or use your own material.
|
||
• The toggle Optimize Source Mesh applies a Automatic Decimation to
|
||
the source mesh. It’s not recommended for detailed meshes, but it can
|
||
help for basic shapes, such as a cube subdivided in more vertices than it
|
||
should be.
|
||
• Setting 1 on LOD Levels will just apply a distance culling (and an automatic decimation if the toggle is enabled).
|
||
• You can apply changes to a prefab instance, as long as the decimated mesh
|
||
were saved to the Assets (otherwise the meshes will be missing, as they
|
||
are stored in the scene data).
|
||
• You can undo the whole AutoLOD process with Edit -> Undo
|
||
• You can put several objects in the drag and drop area. AutoLOD will just
|
||
add the valid ones to the list.
|
||
• You can add a MeshRenderer or SkinnedMeshRenderer from its context menu in the inspector
|
||
|
||
## Warning
|
||
• Generation can take several minutes for a whole scene. Unity will freeze
|
||
during the process but a progress bar will provide a visual estimation of
|
||
what is happening.
|
||
• If the processed object has specific components attached to it, they will
|
||
remain but make sure they still work properly. If they were using the
|
||
attached MeshFilter or Renderer, they will probably be broken, but it
|
||
should be easy to fix in most cases.
|
||
• Please check carefully which objects you put in AutoLOD and understand
|
||
that there are just too many cases that can end up with bugs, especially
|
||
with your MonoBehaviour scripts.
