Material palettes is a useful feature that SimLab Composer provides, it can save your materials progress in a separate external file that can be re-applied easily.
From the material menu select Save Material Palette. Set the path and name for the file and click Save.
Reopen CAD Software and load the saved file, then from the extension menu, go to SimLab composer integration and select Link with SimLab Composer.
As you can see the materials and textures applied in SimLab Composer, are the same materials applied in CAD Software.
Retain Material Palette
This function allows user to keep applied materials in SimLab Composer to the design. Not having this option toggled will re-import the original materials from CAD Software to the design.
Select the palette file that you previously save, and set the mode to material name
