In the Document Properties (in Windows) or in Rhino menu > Settings… > Maxwell Render (in MacOS) you’ll find some general options in a specific section for Maxwell for Rhino:

User Interface

• Decimal Precision: this lets you set the number of decimals shown in the numerical options of the plugin.

• UI size: it will let you choose between two text sizes for the plugin options: Mini and Normal. As the plugin sometimes has to pack many options in small spaces, the default option is Mini, but you can make it bigger if you wish.

• Displayed Texture Size: here you can choose the resolution of the textures shown in the viewport. This won’t affect the render.

MXM Gallery

• Download to Out Folder: if this option is active, the materials downloaded from the MXM Gallery will be stored in the same folder as the render output files. This one can be set in the Rendering panel > Maxwell for Rhino section > Output tab > Folder box. When this option is active, “Alternative Folder” option is disabled.

• Alternative Folder: (this option is disabled if the previous one is active). Here you can set a folder to store all the materials downloaded from the MXM Gallery (in the case you want to keep them in a more controlled folder or create a local gallery based on your downloads).

• To sub-folder: if active, this option will store each material downloaded from the MXM Gallery in their own folder (including their textures); otherwise, all the MXM files will be stored in the same folder as well as their textures. Deactivating this option can be potentially dangerous as some textures could overwrite others.
