Hello, I have briefly checked marketplace guidelines but could not find a similar topic around, so sorry if this kind of guideline for asset creators already exist.
I have a suggestion for the marketplace that maybe enable use of multiple assets acquired from different asset creators in a much better way. It is sometimes a hit or miss to match your favorite texture pack to your favorite character asset. Will it be helpful if designers and Epic create a set of different soft asset/design templates for different styles of graphics and games like color codes and material guidelines?
If content creators agree on such styles with marketplace integration: developers searching for a “low poly style by X Studio | Epic | User” asset in Unreal Marketplace may find and use multiple creators’ assets complying to those soft guidelines quickly. I love the variety the marketplace offers. These guidelines would never be a requirement but an extra channel for different creators to merge their assets much seamlessly in the same project.
This I think would be a win-win as it would create new opportunities for asset creators and enhance prototyping and overall game quality for developers.
