I made a mod and can't proceed ...

[astral-entity]

I made a mod that includes graphical content of others. I can't get in contact with those people because the forum doesn't let me because I'm new here. And if I write a post in an existing thread, where I think a contact request for that related content fits the best, it is disapproved because it is off-topic.

How am I supposed to do anything here if I am not allowed to?

Are their ways to contact them outside of the forum? Like if it's from another mod, the "contact" field would be a good start.

Usually, you can contact the mod dev via the mod portal or the contact option. Maybe also via github or something.
If you can't contact the mod dev, you can treat it as a "No".
In case of doubt, don't use graphical content of others, if the license forbids.

You can use factory base game assets, though, if that helps.

Try to send them a private message again! It should work now because you have made an approved forum post.

Also if their graphics are already in a mod then you can often just depend on the other mod and then use the graphic by referencing the path in the other mod.
