I want to learn how to make mod skins, but I don't know which application is right for my laptop. Intel uhd 600, Celeron n4000

You can give the following a try (these are just options, I'm not recommending any in particular): - 3dsmax (https://www.autodesk.co.uk/products/3ds-max/overview?term=1-YEAR&tab=subscription) - Blender (https://www.blender.org/) These are the ones I know.
