Plugin Issues

Troubleshoot issues with the FastRender plugin installation and operation.

Plugin not appearing in Rhino

If FastRender doesn't appear after installation:

Check PlugInManager

1. Type PlugInManager in the Rhino command line
2. Look for "FastRender" in the list
3. If found, ensure the Enabled checkbox is checked

Filter plugins

In PlugInManager, click on Plugins that do not ship with Rhino to find third-party plugins like FastRender.

Verify installation location

Check if files exist in:

If the folder doesn't exist, the plugin may not have installed correctly. Try reinstalling.
