Have you tried Lagless.gg? I saw an ad for free trials and after messing around a bit it seems nice

Trying to add Sculk Horde to Raspberry Flavored (java.lang.NoClassDefFoundError)

Hey there! I've been trying to add Sculk Horde to Raspberry Flavored. AzureLib works just fine minus Sculk Horde but whenever I add it I get the message:
"Sculk Horde (sculkhorde) has failed to load correctly
java.lang.NoClassDefFoundError: mod/azure/azurelib/animatable/GeoEntity"

Please let me know if there's anything I can do to troubleshoot! Or if it's not possible just gear me up to rip that bandaid off, thanks in advance!

Here's the pastebin for the latest crash:

[1.8] Any way to make vanilla dirt a falling block?

Wanted to add onto this for anyone else who finds it.

GameRegistry.addSubstitutionAlias works, but if you are replacing a block, you need to replace both the block and the block item.
// removed everything but the relevant code public static Block newBlock= new FallingBlockDirt(); // needs to extend Dirt Block... @EventHandler public void preInit(FMLPreInitializationEvent event ) { GameRegistry.addSubstitutionAlias( "block.id.to.replace", GameRegistry.Type.BLOCK, newBlock); GameRegistry.addSubstitutionAlias( "block.id.to.replace", GameRegistry.Type.ITEM, new ItemBlock(newBlock)); }In the case of the op, I think he was missing this second substitute alias. As the error he mentioned is similar to what I saw in that scenario.

He would need to make a class that extends Block Dirt ( what he's replacing ), but overwrite some methods with those of BlockFalling ( what gravel uses ).
If he tried to use the BlockFalling class, or a new class that extends that... that would also fail as it doesn't match 1-1 what the BlockDirt was expecting.

In my case, I was using 1.7.10, so there may be slight differences that I haven't noticed.

Edit: Forgot to mention. Don't register the new block. The addSubsitutionAlias is splicing the new one in for the old one, so it shouldn't have a new registry.

orbital strike cannon - mod or schematic for litematica

just found this thread, does the mk6.1 litematic actually fix the fishing rod issue or is it still bugged?

Struggling to understand how to write custom mod shaders

I've learned how to write basic JSON files that work with vanilla shader templates (like the spider eye or blur effects). However, I don't understand how to access uniform variables. For example, I want to create a blur that fades in smoothly over time. I'm also interested in how to stack or overlay shaders on top of each other — the way mods like Blur and Enchanted Visuals do it.
Could anyone explain the general approach or point me to relevant resources for Forge 1.20.1?
