It's been mentioned in the new patch that there's an "Option added to have local fields for lesser foreign races or force via showcase for G1 ('H'ome field)."

Anyone know how this is added to the Showcase files? Just eager to get started.

Cheers

Yep, I discussed this with Mark last week. Overseas races that are Group 2 or below should now contain only horses from their own country, unless you prep them to include other horses. When it comes to overseas Group 1 races, you can now add an "H" on the prize money line (for example, "100000,H" or "100000,F14,H") in the showcases file, which should restrict these races to only horses from their own country.

For those of us that are building worldwide schedules, it's a fantastic option to have.

Thanks for your help.

This is amazing, so if I make maiden races from all of the foreign countries, they will contain just horses from that country?

Yes, although if the game can't find enough suitable horses, UK horses can still appear in these races, so you need to make sure the overseas pools are all at the correct size.
