I want to make Grasleaves in Blender and use them in Unreal Engine 4. In the Engine there is an Option make a Matieral double-sided. In Blender, is there a way to have both sides of my mesh unwrapped in one UV-map? I know about the Doublesided option but haven't worked out what it does exactly. Also i've been searching for a soloution on the internet but haven't found anything, but all the info i came across seemed outdated. I can't imagine, that there's no way to do this, especially since alot of assets i bought online seem to work just like that. Thank you for your help.
