Enhancement

Pretty sure Polymer has built-in support with WTHIT. Do you have it on the client?

Have it on the client, but it doesn't seems to work.

What version of Polymer do you use? Seems like the compatibility is only recently enabled for 1.20.6.

Patbox/polymer@0c47528

Using the latest 1.20.6 build, which was published on Modrinth.

Can I get your latest.log? Paste it on https://gist.github.com/.

I hope it's fine that I used pastebin.

I imagine it is caused by the barrier/structure void blocks being blacklisted. So they would need to be either removed or overriden (not sure if polymer can do that without mixins, as I'm not versed with the api)

Added API to remove things from the default blacklist. Also changed the the impl of the blacklist to be easily bypassed by plugins, I'll PR to Polymer soon.
