Hello,

How do megascans assets work ? Are they very good because of texture size, polygons number ?

I'm a bit lost here.

Thanks for the help !

Can you provide more context? What are you talking about? Google suggests that you might be referring to something from https://megascans.se/, but you need to be explicit.

Moreover, you are going to use specific assets for a specific purpose; you aren't likely to receive focused advice if you ask about a whole asset store or general technical aspects.
