Magdalena Dadela was kind enough to upload a free Marmoset Toolbag 3 scene setup featuring her amazing Goblin. She is a true master of character art, so this is a great chance to learn something.
This is a Marmoset Toolbag 3 scene setup. You can open the scene and find out the material settings and lighting for yourself. The majority of textures are in 2k resolution.
Extract the ZIP file and double click on the scene file to open. All the textures should be linked and ready to roll.
