How to Decimate and Bake Atlas in Autodesk Maya

This guide is part of the RapidPipeline 3D Plugin Actions Knowledge Base. It shows how to Decimate and Bake Atlas on Autodesk Maya; if you'd like to know more about it, please check out the following links:

• Learn more about the Decimate and Bake Atlas

1. On the Menu Bar, click on DGG RapidPipeline and choose Show Plugin Window.
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 and Bake Atlas.
4. Press the Run button. :::tip Decimation actions by default use a deviation target. When the Deviation Percentage is more than zero, the Face Target will act as an upper limit for the face count, instead of acting as a forced target. Increasing the Deviation Percentage will allow the optimizer to go lower when possible. However if you simply want to reach an exact face target, the Deviation Percentage should be set to 0. :::

• Use the Maya Plugin
• Select a part
• Run "Decimate and Bake Atlas" Action
• Examine the results

This tutorial shows how use the RapidPipeline Processor Plugin in Maya to simplify the geometry of a model with decimation and bake the material and texture information into a new UV atlas. For more information see the Maya Plugin Documentation.

To fully check the topology optimization by enabling Wireframe on Shaded from the Viewport Shading drop-down menu, so you can see a wireframe view of your models.

Finally, you can compare the materials and texture count of input and output by opening the Hypershade window (Windows > Rendering Editors > Hypershade, or pressing the shortcut Shift + T). Make sure your object is selected and open the Material Viewer panel at the bottom, and click on the Graph Materials on Selected Objects option.
