Adaptive Decimate for Blender 4.0+

Alpha Version


Just like adaptive subdivision, adaptive decimate will decimate your object depending on how close it is to the camera.


Instructions for Use:

1.) Apply the Adaptive Decimate modifier to any object

2.) Max Range to 0 in the Decimate Settings

3.) Set Max Decimate depending on how you want your object to look at maximum range

4.) Set Min Range to how far your object has to be to start decimating

5.) Set Max Range to to how far your object can be before it stops decimating (Will appear as Max Decimate setting)

6.) Copy Active Camera's settings in the Camera Settings

7.) Set Culling in the Limit Settings (0 = Nothing | 1 = Set as Max Decimate | 2 = Delete Geometry)


Substep Setting

What are substeps?

Substeps are how many steps the decimate will take to transition from the Min Range to the Max Range. A higher substep count will lead to a smoother decimation rate.


How do I modify substeps?

Due to limitations, changing the substeps require a bit more steps to follow

1.) Change the Substep settings

2.) Make the Modifier a single user (To avoid messing with other Adaptive Decimate users)

3.) Go to the Geometry Nodes panel

4.) Copy the Red Node group depending on how many substeps you have. Add this to the geometry output (If you have 5, make sure to add 5)

Substeps Node Group

5.) Connect the correct nodes to the correct sockets

6.) Adjust the steps and values accordingly.

Settings for 5 Substeps

This part will be automated in future versions of the modifier.
