PolyFactory 0.7.2 has been released!
After quite a bit of work, PolyFactory has Smeltery and metal casting!

Tinkers style metal casting for PolyFactory
Non automatable, but accessible early game (excluding smeltery, as I haven't made early game version of it yet). For automation you would just use Mechanical Spout instead.

Server side as always ofc.

Speakers and Record Player (for PolyFactory)

A Minecraft screenshot containing a player base in a cherry biome. The image contains modded blocks, from decorative crates to rotational machines.

After a bit of a hiatus, a release of Polymania 0.3.0-beta.1 for Minecraft 1.21.4 is here!
It's a kitchen-sinky modpack, allowing for fully modded experience without installing a single mod on the client.

Read changelog / download it here!

Moving the camera is also not really feasible, since whatever things render depend on client player rendering position, not just camera position (aka it would cull things out too much). Also this mod needs to work in general survival context and with good compatibility with things.

Generally that would be tricky. Shaders are sadly a no-go, because mods client mods like Iris (and lesser extend Sodium) break it. While it's true that better block hitboxes could be done, they would only apply to collisions (not breaking) and would require quite lot of entities for singular block.

Any more faster rendering and better block hitboxes hah. Well, at least for now...

Testing rotating structures, fully server side ofc. Not sure if I will end up adding it to PolyFactory (through maybe as it's own mod? Will see). #mcdev #minecraft

Happy holidays from NucleoidMC! :)

Here's showcase of the display from the image. Cut the last part as bsky needed it to be under minute. Only thing cut out is me clearing the screen.

Showcase of new and changes done in this update. Conveyor on left connects to Item Packer with purple bundle. Which is connected to an Data Comparator via red cable. Data Comparator takes input from Text Input block via blue cable and outputs result via green cable. That cable connects to Redstone Output, on which Green Fixture Lamp is connected. In background you can see some gears connected randomly to each other, with slime and honey particles flying around it. Near it you can see floating text "PolyFactory 0.6.1" Rest of the bottom and right side of the image shows multiple colored Fixture Lamps, with some turned on and some off.

An 4 input + reset and clock controlled 8x8 lamp-based display. Connected with cables and gated cables.

PolyFactory just got an 0.6.1 update (for MC 1.21.4)!
Improves the data system by allowing it to pass through conditionally (showcase video in replies). Also adds nice way to pack items into bundles and shulkers! And more!

The main server has finally been updated to 1.21.4!
Most games are ported and should be playable, and we hope to get the rest onto the server soon™.

Have fun playing!

All my maintained mods available on 1.21.3 have been updated to 1.21.4!
If a mod wasn't updated to 1.21.4, but has a 1.21.2/3 version, the 1.21.2/3 version should just work. Through report if you find problems.

If you make Modrinth Modpacks and wanted to make a server jar/installer, I made a perfect tool just for that! mrpack4server can be used standalone for users and preconfigured for pack makers. Also provides public web api for jar creation, so you can just link to it.

All my (supported) mods are now on 1.21.3! Mostly direct ports.
Polymania modpack also released an 0.2.1 update, making it joinable from 1.21.3, through with some issues (as it's still on 1.21.1).
Polymer Ports will get an update once the upstream mod is available.

Hello BlueSky! 👋
We're Nucleoid, an open-source minigames server for modern versions of Minecraft.
Find out more at nucleoid.xyz !

Yep, Polymer. It's pretty flexible in what you can do with it, since it gives tools to create custom server side content (blocks, items, entities, etc)

On server, they are regular modded blocks (so they have own id and any mod/datapack sees them as a custom block). On client they do use display entities (for PolyFactory) with barrier or purely vanilla blocks (Brewery). State-based ones are also possible and some of them from Polymania are.
