Posts from How do I modify maps from the campaign? Auto-translated

Could you please tell me how to modify individual maps from a campaign, for example, from Erathia (if this is possible)?

Well, first you need to extract the campaign from the game archive,

then extract the desired map using the in-game campaign editor, edit it with a map editor, and update the map in the campaign.
However, I can't help you with repacking the campaign back into the game archive. On the other hand, you can load the campaign as an add-on.

How to extract a campaign from the game archive?

Can you tell me how to modify individual maps from a campaign, for example, from the Erathia campaign (if this is possible)?

Why would you want to do that? Just play through it without making any changes; it's all perfectly playable as is!

yes, I've completed all the campaigns and RoE, and I just want to fix something.

Interesting idea, retrieving maps from the archive could be considered.

How do I extract a campaign from the game archive?

I already sent you the link. Open Resource Editor, select file/open resource file, then specify the path to the Heroes directory/data/h3bitmap.lod, select files with the .h3c extension, select the desired file, and extract it.

Thank you very much, everything works! And if possible, could you tell me how to use the other programs from this archive?
