Hey, nice asset pack.
I noticed on import to Unreal that you are using multiple material slots for items.
Is there a reason you use this method instead of baking textures onto a single map?
Given the low poly nature of the assets I imagine for a lot of use cases the extra draw calls won't be a major issue.
However, it would help to reduce overhead in game-engines if there were fewer material slots being used.
I will test out a few scenes using your default texture set up and try to determine how big the performance hit is due to extra draw calls.
Just food for thought!
Overall I like the content and style of the pack and it should prove helpful when blocking out and performing first passes on levels!
Thanks for sharing a cool asset pack!
