1. On the Menu Bar, click on RapidPipeline and choose Load Plug-in.
2. Select the model you want to optimize (if no selection is made, the whole scene will be processed).
3. Inside the Plugin window, choose the Action Decimate Mesh.
4. Press the Run button. :::note Please note that if a deviation target is set, it acts as a cap. If you want to reach the exact specified face target under any circumstances, Deviation Target must be set to 0. :::

• Use the 3ds Max Plugin
• Select a part
• Run an Action
• Examine the results

This tutorial shows how use the RapidPipeline Processor Plugin in 3ds Max to simplify the geometry of a model with the “Decimate Mesh” action. For more information see the 3ds Max Plugin Documentation. The Add-On runs on a powerful 3D data optimization and automation toolset, for more about this see the 3D Processor Reference.
